Question:

Im looking for new wobble rollers for my boat trailer but have no idea on sizing. I took one off but nothing matches what you have. Its rubber and held on using a 1/2inch bolt with a sleeve inside the roller. The bolt screws directly into the arm which holds the rollers in position. The center of the roller is steel. Black rubber roller is 3inch wide by 4 3/8 inch diameter. Inside diameter hole is 7/8 Im certain this is no a repair job and trailer came with this arrangement using the sleeve.

We have a couple of wobble rollers that are 4-3/8 inch diameter and 3 inches wide. We have # YR343R-6P which fits on a 3/4 inch shaft or # YR343R-5P that fits a 5/8 inch shaft.

Roller # YR343R-6P is the best option since the center hole is slightly under 7/8 of an inch to fit a 3/4 inch shaft.

Roller # YR500YW-7P has a center hole slightly under 1 inch to fit a 7/8 inch shaft but the diameter is 5 inches. If the slightly larger diameter would work then this is a good option. Otherwise you would need to replace the 7/8 shaft with a 3/4 shaft (or bolt) and use # YR343R-6P.
