This is the bearing we use in our glider rocker bearing kits 4181-0001A and 4181-0002A. It's a versatile bearing made in the USA that can be used for many different projects where a low speed bearing is all that's required. They are made of steel construction throughout. They have a light zinc finish and are lightly greased internally when assembled. The metal shield prevents dusts and contaminants from easily entering the bearing. The bore is smooth and fits a standard 3/8" bolt perfectly. This allows you to use any length bolt you need to build or repair your rocker. We have personally repaired several rockers with this bearing with great success and happy customers.
Please note we do not have brand specific data... we only know that this bearing fits many chairs. Please scroll down to the bottom of this page for specific measurements.
