What type of bearing is needed for replacing a sleeve bearing?

When replacing a sleeve bearing, a friction bearing is the appropriate choice because a sleeve bearing itself is a type of friction bearing. Sleeve bearings consist of a cylindrical sleeve that allows rotation with minimal friction, typically relying on a lubricant film for smooth operation.

Using another friction bearing maintains the same operational principle, ensuring that the replacement component performs similarly to the original in terms of load support and motion. Other bearing types, such as ball bearings and roller bearings, operate on different principles involving rolling elements that reduce friction in other ways and are generally suited for different applications where load distribution and speed vary significantly.

Cylindrical bearings, while similar, refer to the shape of the bearing rather than its function as a friction or rolling bearing. In summary, choosing a friction bearing ensures compatibility and performance continuity when replacing a sleeve bearing.
