Video Transcript for Review of Yates Rubber Boat Trailer Parts - Roller and Bunk Parts - YR450BLK-400BLK

Today, we're taking a look at a bow roller assembly with bells, for a four inch wide bracket. This bow roller assembly replaces the bow roller and bells, shaft and hardware, on your boat trailer. It eases loading and unloading of the boat, and supports the front of the boat as it sits on the trailer, to help absorb road shock while the boat is being towed. The end bells insure that your boat does not scrape along bolts or roller brackets.We're looking at a durable, thermal, plasticized rubber construction. It's a non-scratching material. It's stronger and more durable than traditional rubber, and softer, and more pliant than polyurethane.

It's black in color, and it does come with the zinc shaft and hardware, with yellow zinc finishes that are rust and corrosion resistant.Product's made in the USA. This is designed for a four inch wide bracket, which would install here, between the roller and the end bells. That shaft that it comes with, that bolt measures six inches long, from the bottom of the bolt head to the end of the threads, by a half inch diameter. It also comes with the locknut, and it comes with a flat washer, one for each end.Now, the roller itself, this portion here, measures three and three quarter inches long, and then it has a diameter at the widest point, by three and one quarter inches. The end bells have a diameter, at the widest point, of five and one quarter inches, and then the diameter here at the attachment point is three and a half inches.That's gonna do it for today's look at the bow roller assembly with bells, for a four inch wide bracket..

I was extremely happy with it after installation. I purchased it to replace an old one that was marking up my bow with black marks. This one is muck better than that old one, but I still get more faint black marks on the bow . Just wish I went with the more translucent yellowish one that most others have gone with. 544171

Considering the the original part on my trailer lasted 25 years before needing to be replaced, the wear so far on the replacement part is way more than it should be. The first one was made in the USA......no idea where the replace meant came from ...but I bet I could guess 582242

Although we bought this part as a spare and have not used it, it is exactly what we wanted. George from etrailer.com was excellent and kept us informed on the backorder and shipping of the bow roller. I would buy from him again because of the customer service alone. Thank you so much. Highly recommend! 421537

  • How to Prevent Metal Bow Roller Brackets from Contacting the Boat
  • Almost all bow roller assemblies have an industry standard hardness of 85a durometers. I was able to call my contact at Yates to confirm this. I do have a solution for you but we do not have any bow rollers with a hardness rating greater than 85a durometers at this time. However, I believe the problem you are experiencing can be eliminated using a wider roller as this would in turn dissipate the weight more evenly to minimize contact with the metal brackets. I recommend using the Bow...

  • Bow Roller Recommendation to Fit 4 inch Roller that is Too Long
  • Looks like you have the part # YR450BLK-400BLK installed and are needing the next size down which happens to be the part # YR300BLK-325BLK. This fits the same 1/2 inch diameter shaft but is 1 inch shorter than what you have. Your bell ends being deformed would not be a good sign.
