Video Transcript for Performance Tool Carbon Fiber Digital Caliper Review

Today we'll be looking at the Performance Tool four inch carbon fiber digital caliper. Part number PTW80157. This allows you to read from 0 to 4 inches or 0 to 100 millimeters. It moves in 100ths of an inch or 1/10ths of a millimeter. It has a nice LED screen. You hit the on button and it's easy to read.

You can switch between millimeters and inches. Right now it's in inches and now it's in millimeters. Just by the touch of a button. We also have our zero capability so when we move it down our measurement tool, if we want to measure something and see the difference between another measurement, we can hit the zero button and it shows us the difference. This is a negative distance or a positive distance.

Take it back to zero and hit the zero button again so we can start back from zero inches or zero millimeters. This allows us to measure the outside diameter or the inside dimensions with the other side. Now we can show you in action. On our trailer here, we pulled off our seal. Usually it's stamped with the measurements on it, but this one has worn off over time. WE can use our tool to find the inner dimension of our race.

2.18 inches. If we need to figure out the outside diameter, that'll be 3.35 inches. Other measurements that we might need to know. Come to our shaft. We've got the bearings that sit on our shaft so we might need to know the diameter of our shaft.

We can come up, be 1.24 inches and that'll be for our inner or our outside bearing. If we need to figure out our other, the larger bearing, the inside bearing, we do the same thing. 1.74 inches. Now if we need to know the difference between the two, we come up we get the inside bearing, we hit our zero button, that zeros it out, and we can come to our outside bearing and we see there's almost a half inch difference between the two bearing sizes. Same works if you want to figure out the dimensions here for our race because that's where it sits. This is where our race sits. If I want to do difference in that. I'll take our meter, I'll measure the inside diameter of our race, I'll hit the zero button, and then I can come and measure the outside distance of our race and see if there's any difference at all. Which, there's not, but if there was it would show us. There would be a negative difference or if I measure something bigger, it would show us a positive difference. That's it for a look at the Performance Tool 4 inch carbon fiber digital caliper. Part number PTW80157.Speaker 2: You can find this and everything else right here at etrailer.com What's up man.

4" Carbon Fiber Digital Caliper - PTW80157

Average Customer Rating:  4.9 out of 5 stars   (20 Customer Reviews)

Works as described.

Good product



by:

It works great and it's just plain fun. I bought it to measure bearing buddies and spindles. It works for that but it also has been great for measuring the diameter of carbon fiber tubes I'm using to build a sailboat mast and spars.

It gives instant metric to inch conversions - just push the in/mm button and the measurement in the display converts.

I've used it at least a couple of hundred times and it's still on the original battery.

Pro tip: Close it all the way before you turn it on.



by:

I have always wanted a digital caliper now I have one. I have always relied on my older read out types since this is the one etrailer uses I will be able to take the same measurements they do . My local bearing supplier has priced themselves out of the market so I use etrailer !

  • How to Measure for Replacement Trailer Hubs
    We do not have any trailer hubs that use a 1-3/8" diameter inner bearing and a 3/4" diameter outer bearing. Bearing diameters are measured to the thousandth of an inch using a digital caliper like part # PTW80157. I have attached a photo that shows the correct measurements that will need to be taken in order to find the replacement hubs. I will need the B, C, and D measurements from you. Once you can provide me with these measurements I would be happy to see if we have options for you.

  • How to Find Correct Wheel Bearings for 2008 Adams Horse Trailer
    In order to find the correct wheel bearings, you can take apart your 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 would need to use a digital caliper such as # PTW80157 and measure your spindle to the thousandths of an inch where the bearings ride. You can use the photo I've attached to see exactly where you need to measure. I've also added a link to a...

  • Replacement Oil Seal for Trailer Hub with Oil Bath System
    The diameter of the inside and outside of the seal is needed to give you the correct replacement. I unfortunately can't give you a fit based on VIN or manufacturer. I recommend using a digital caliper like # PTW80157 to get those measurements as they need to be precise. With a failed seal, I recommend measuring the inside of the hub and the outside of spindle to get the correct diameters.

  • Measuring Axle Diameter to Determine the Capacity
    When measuring an axle to determine the weight capacity you'll want to measure along the actual axle tube. Anywhere between the spring seats will work fine. I also recommend measuring with a digital caliper like # PTW80157 to get an accurate measurement. A digital caliper is a good tool to have when measuring for replacement bearings and other parts as well. Once you have the axle's diameter the typical capacity based on measurements are: - 1,000-lb - 2,000-lb Axles: 1-1/2 inch - 1-3/4...

  • Measuring For Correct Hub/Drum Assembly Replacements On 2007 Trailstar Tracker P-25 Pontoon Trailer
    On your Trailstar Tracker, I have no way to cross reference the axle, spindle, or hub or drum you have. The way for me to help you with all of this is to use a digital caliper like # PTW80157 and take some measurements of your spindle for me. If you are able to get the bearing numbers that are printed on the outside of the inner and outer bearing of each hub, I can also help from those numbers. Getting you the right bearing sizes is extremely important for your trailer to function properly....

  • Is a Small Difference in Wheel Pilot Hole and Hub on Hub Centric Axle Okay
    With hub-centric hubs like those on your trailer, it is important that the center pilot hole of a wheel is the same exact size as the hub bore. The hubs will center the wheels using the hub bore and the pilot hole of the wheel, so ideally this measurement should to be identical or it could potentially cause issues. Obviously, the difference between the 2.55 inch wheel pilot hole and your 2.5 inch hub is extremely small, but this tiny variance can still cause the hub to basically be secured...

  • Finding Bearing Numbers or Measuring Spindles for Hub Replacement Compatible with Trailer Axles
    Unfortunately, there is no way to tell if the hubs will fit without measuring the axle shaft or getting the bearing numbers, so disassembling one hub is required. Although this may sound a little difficult, it really is an easy process, but it will require getting your hands greasy. If you can let me know the bearing number on the face of the inner and outer bearing, I can see what hub will fit your spindle based on those numbers. Those numbers are normally printed on the larger side...

  • Replacement Grease Seal for Older Trailer Using Seal 41360
    I was not able to find any grease seal to cross-reference with part 41360 but we can still help you identify grease seals with the correct dimensions. You will want to use a precision digital or dial caliper like # PTW80157 to measure the rear hub bore diameter and the spindle diameter where the seal rides. If you refer to the linked diagram the point you'll need to measure to determine the correct inner diameter for a grease seal is noted as point B. This is where the seal's inner rubber...

  • How to Pick Out Grease Cap for Trailer Hub
    We have several grease caps that could potentially work for the hub on the axle you have on your enclosed trailer, see link to the right. To pick out the correct size one you will need to know the pilot hole diameter on your hub. To do this, remove the wheel and tire and remove the grease cap from the center of the hub. Usually it is a metal cap that is just lightly hammered into place. Use a screwdriver to pry off the cap. Clean the grease off and measure the opening with a dial caliper...

  • Trailer Hubs For a Spindle that is 1-1/4 Inches
    If the hubs you need are replacements, the easiest way to find new ones would be to check the inner and outer bearing numbers of your previous hub, which will be stamped right on the side of the bearings. If those are worn or otherwise unavailable, you could use a digital caliper such as # PTW80157 and measure your 1-1/4" spindle to three decimal places. You can use the photo I've attached as a reference for where to measure. You are also going to need to know your wheel bolt pattern to...
