Video Transcript for Yates Rubber Boat Trailer Parts - Roller and Bunk Parts - YR450B-400B Review

Today we are going to be taking a look at a Bow Roller Assembly, this bow roller assembly replaces the bow roller, end bells, shaft and hardware on your boat trailer. It eases loading and unloading of your boat, and it's going to support the front of the boat as it sits on your trailer. It's also going to help absorb road shock while the boat is being towed. The end bell's, which are these components right here, these insure that the boat does not scrape along bolts or roller brackets. The roller bracket would sit right here at the edge of the roller on each side, it would detach using that center shaft or center bolt. The material is a thermal plasticized rubber construction that's TPR. It's a non-marking, non-scratching material, it's stronger and more durable then traditional rubber, and it's softer and more pliant then polyurethane.

This is blue in color all the hardware is a nice sturdy construction that's going to be a zinc shaft, and hardware with yellow zinc finishes, highly corrosion resistant, great for water applications. The products are made in the USA. This is designed to work a 4 inch wide bracket, again it would sit in these grooves here, and attach using that center shaft. The shaft dimensions, so the dimensions of that bolt from the bottom of the bolt head to the end of the threaded portion, that's going to measure about 6 inches long, and it's going to have a 1/2 inch diameter. When it comes to the dimensions of the roller, that's just this center piece here, it's going to be hard to tell but that's going to be 3 3/4 inches long and the diameter at the widest point is about 3 1/4 of an inch. The end bells, when it comes to the diameter of those at the widest point here on the edge, that's going to be about 5 1/4 of an inch.

The diameter at the attachment point, which would be right here edge to edge, is going to be about 3 1/2 inches. It's a complete assembly, again it's going to come with, the roller, two end bells, and it's going to come with the appropriate hardware. You are going to get that center shaft or bolt, you're going to get a flat washer, you are also going to get another flat washer, and then a nylon lock nut. That's going to do it for today's look at the Bow Roller Assembly.

I am very pleased with the product, although I have not yet installed it. I'm sure it will fit my trailer since it is the same brand, size and profile as the black rubber roller it will replace. The two outside "bell" rollers are actually larger than the originals which is a plus and this material will not leave marks on the hull like black rubber. 672979

Do you have a question about this Boat Trailer Part?


  • 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...

  • Replacement Bow Roller with Bell Ends for a 2011 Skeeter SX200 Boat Trailer

This assembly will be a nice upgrade for your trailer as the thermal-plasticized rubber will help to absorb shock without marking the boat up and the included bell ends will ensure there is no contact with the mounting bracket.

  • Replacement Bow Roller for 5/8 inch Shaft
  • I have a few different options for you. The Rubber Endcap # YR134-5 that you mentioned can be used with keel rollers, spool rollers, or bow rollers. If you are wanting to stick with a bow roller, We do have a Bow Roller Assembly # YR450B-400B available that comes with a 1/2 inch shaft. This will eliminate the need to find a bow roller with a bigger shaft hole. I did go out to the warehouse to see with it was possibly that a 5/8 inch shank could fit in a bow roller that has a 1/2 inch...
