Determining the Bolt Pattern

The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.


Bolt Pattern - Even

On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: 8 on 6-1/2 means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)


Bolt Pattern - Odd

To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: 5 on 4-1/2 means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)


Bolt Pattern - Side

Measuring the distance (D) from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

  • How Full Should Boat Trailer Hubs be Filled with Grease
    Hey Duane, Once the bearings are packed with grease and the hub is on the spindle you'll need to slowly pump grease into the spindle until you see it start to seep out of the outer bearing. Be sure to use a manual grease gun so the grease doesn't fill the spindle too quick and blow out the seal. This will be the same process for both your standard trailer and your boat trailer. I'm attaching a helpful article on replacing bearings that goes over this as well.

  • Replacement Axle Tube for a Habor Freight Model 90154 Trailer
    In order to determine if we have a new axle beam that will work for you, we would first need to do some measuring. The measurements that will need to be taken are from the center of each spring seat on the axle you have now as well as the distance between the two hub faces. I have attached a photo of this for you as well. The most important measurement that you need to verify is the hub face as the spring seats can be moved. For example, if you have a hub face of 60" you can then use...

  • Replacement Boat Trailer Idler Hub with 4-1/4" Depth and 1-1/16" Spindle
    Hey Larry, The Trailer Hub Assembly # AH15450ECOMP you're looking at is for a tapered spindle and won't fit your boat trailer, but I have the Trailer Idler Hub Assembly # AKIHUB-440-2-G-2K that looks to fit your specs a bit better. This hub is rated for 2,000 lbs and has a 4 on 4" bolt pattern so as long as that matches what you have then you'll be good to go!

  • Depth Measurement For Hubs That Fit A 1" Straight Spindle
    We do have hubs available for a 1" straight spindle in part # AKIHUB-440-2-EZ-1K. This hub measures 4-1/4" deep so it will run a bit longer than the hub you are looking for. There are a total of 4 hubs that we carry for a 1" straight spindle and all 4 would be identical as far as depth. A lot of these older boat trailers use hubs that are trailer specific, and it may prove very difficult to find. We do carry replacement spindles like part # TRU59FR, if you want to change it out for a more...

  • Recommended Hub for a Boat Trailer w/ L44649 Inner and Outer Bearings
    The bearings that go on a 1.06" spindle are item # L44649. These are found in this configuration on 2,000 lbs - 2,700 lbs axles. If you can find it there is typically an axle tag or engraving somewhere on the axle that'll have a serial number or even the capacity on it. To replace the hub you will need one of the following depending on your bolt pattern: 4 on 4 - Galvanized - item # AKIHUB-440-2-G-2K 5 on 4-1/2 - Galvanized - Item # CE13315 Feel free to email me back with any additional...

  • Trailer Idler Hub Assembly For a 1" Diameter Spindle That is 4-1/4" Long
    It sounds like you are needing the Trailer Idler Hub Assembly # AKIHUB-440-2-G-1K for your trailer. This hub fits the BT8 Spindle # TRU59FR which is 1" in diameter and has a length of 4-1/4" long from the inner bearing landing to the end of the threads. The Idler Hub Assembly # AKIHUB-440-2-G-2K you found fits a BTR Spindle # TRU44FR which has a diameter of 1.063" for the hub bearings.

  • Recommended Trailer Axle and Galvanized Hub Assemblies for 2,000 lb Capacity Trailer
    The Dexter Trailer Axle with Idler Hubs - 4 on 4 Bolt Pattern - 60" Long - 2,000 lbs # 20440I-ST-60 is powder coated, but not galvanized. The best we can do to make sure it wears well with all the salt water is to instead use the same Dexter Trailer Axle Beam with Standard Spindles - 60" Long - 2,000 lbs # T20BTR-6048 but change out the assemblies. You will want the Trailer Idler Hub Assembly for 2,000-lb Axles - 4 on 4 - Galvanized # AKIHUB-440-2-G-2K for that additional corrosion...

  • Replacement Hub With L44649 Bearings on Tracker Boat Trailer
    Appreciate that info and there are two hubs with inner and outer L44649 bearings, with the right one depending on your wheel bolt pattern (as we don't have any way of knowing specifically what hub is on an '87 Tracker trailer). Both are for 2,000 lb axles and have a grease seal that measures 1.50" inner diameter which I recommend ensuring you have. Here are the options: - 5 on 4-1/2" Bolt Pattern: Trailer Idler Hub Assembly for 2,000-lb Axles # AKIHUB-545-2-G-2K - 4 on 4" Bolt Pattern:...

For this size you will want the Trailer Idler Hub Assembly item # AKIHUB-440-2-G-2K. This hub is designed for 2,000 lbs axles with BTR spindles, has a 4 on 4 bolt pattern and accommodates wheels that are 8" to 12". The assembly comes with the required bearings, races and grease seal. These are sold individually and they are better. If you would like Bearing...

  • What is the Difference Between Trailer Hubs # AKIHUB-440-2-G-1K and # AKIHUB-440-2-G-2K
    The two hubs you mentioned, # AKIHUB-440-2-G-1K and # AKIHUB-440-2-G-2K fit different spindles. More specifically they use different bearings and seals. First, hub # AKIHUB-440-2-G-1K uses L44643, with a 1 inch inner diameter, as the inner and outer bearing, and the seal is a 34823, which has an inner diameter of 1.249 inches and outer diameter of 1.983 inches. Based on your information this sounds like the correct replacement. Check your old bearing numbers or you can take measurements...

  • Replacement 4-1/4 Long Idler Hub with 1 Bearings and 1.5 Grease Seal
    We do have a replacement for you with the Trailer Idler Hub Assembly # AKIHUB-440-2-G-2K. This uses inner and outer bearing # L44649 which has a 1.063" inner diameter and then a grease seal with a 1.50" inner diameter like you mentioned. From the 4 bolts in the background I'm guessing you have a 4 on 4" bolt pattern just like this hub has. The only difference is that it looks like you put bolts through your hub each time whereas this idler hub already has bolts installed. This means that...

  • Trailer Wheel Hub to Match 2,200 Pound Lippert Spindle

The hubs that fit come in either a 4 on 4 bolt pattern, like idler hub # AKIHUB-440-2-2K, or 5 on 4-1/2 bolt pattern, like part # AKIHUB-545-2-2K. We also have the same hubs galvanized; part # AKIHUB-440-2-G-2K for the 4 on 4 and part # AKIHUB-545-2-G-2K for the 5 on 4-1/2. There's also a hub and drum that fits if you need brakes...

  • Recommended Galvanized Hubs Assemblies With 4 Bolts For Boat Trailer
    Since you have the spindles with the zerk on the end, I recommend the EZ lube that you mentioned because it is designed to give you easy access to that zerk by removing the plug and not the entire cap. For this assembly, you will want the Trailer Idler Hub Assembly for 2,000-lb E-Z Lube Axles - 4 on 4 - Galvanized # AKIHUB-440-2-G-EZ-2K. If you really don't want the EZ lube access, you can use the AKIHUB-440-2-G-2K with the solid caps. We don't have any assemblies already grease packed...

  • How to Determine Correct Hub For Trailer
    I can tell you how to determine if a hub will fit your trailer, but we don't have any way of knowing if the one you asked about will fit a Right-On dolly trailer. First, you need to know the weight rating of your axle, and also what bearings your current hub has. You will need to take apart your current hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them. If you are unable to find them, you need to...

  • Determining BT8 or BTR Spindle on Trailer
    The easiest way will be to pull off a trailer wheel and hub and then use a caliper like # PTW80157 to measure the spindle diameter where the bearings ride. If the diameter is .99 then you have the BT8 spindle or if it's 1.06 you have the BTR. The trailer hub # AKIHUB-440-2-G-2K you referenced would be what you'd need if you have the BT8. If instead you have the BTR you'd want the part # AKIHUB-440-2-2K.

  • How to Choose Correct Replacement Hubs for Boat Trailer with 2,200 lb Axle
    To ensure that you get the correct replacement hub assembly you need to check the part numbers on your bearings and your grease seal. If you pull the hub you should find them stamped right on the bearings and seal themselves. Luckily trailer axles have become more standardized in the recent past so I can tell you that they should be # L44649 bearings and your seal should be a 10-9 (with an inner diameter of 1.50"). If this is the case then I recommend going with galvanized hubs as they...

  • Recommended Trailer Hubs with 4 on 4 Inch Bolt Pattern for CE Smith Trailer Axle Beam CE33201GA
    The correct trailer hub with 4 on 4" bolt pattern to use with the CE Smith Trailer Axle Beam part # CE33201GA is the Trailer Idler Hub Assembly part # AKIHUB-440-2-G-EZ-2K. The spring seats can then be moved in 1/4" on each side to match your 47" spring center spacing. The Trailer Idler Hub Assembly part # AKIHUB-440-2-G-2K will work but you would want to use the above E-Z Lube option instead as that is what the axle has.

Please note that the seals which come with these have an inner diameter of 1.500" so you will need to use part # 34823 for a grease seal instead as it...

  • How to Select Replacement Hubs for 1970s Dilly Trailer with 4-Lug Hubs
    The best way to select a new hub is to match it based on the bearing set used in the original part. New hubs must use the same bearings as your old ones in order for them to fit on your spindles, so if you can find the part numbers from your inner and outer bearings you'll be most of the way toward knowing the right replacement hubs. Please refer to the linked photo that shows the usual placement and appearance of bearing part numbers. With those part numbers you can directly search on...

    Unfortunately, we aren't able to look up the hubs used by a particular make and model trailer, although I sure wish would could as it would make life a lot easier! The good news is that it's pretty simple to determine which hubs you need. The easiest way to determine which replacement hubs would be needed would be to pull one of the hubs and get the reference number engraved/stamped/etched onto the side of the cages that hold the roller bearings.
