Tread & Core: Solid Cast Thermo Compound Bearing: Sleeve Bearing/ also known as a bushing  From our Caster Expert: "These casters use a bushing and are ungreased. They can be left that way, but they may build up rolling resistance over time. It's recommended to add high-temp grease to make the casters last longer and roll more smoothly. These casters come with a zerk axle for adding grease.
