How does the Performance of Sleeve Bearings and Ball Bearings Compare?

 Back to FAQ

When choosing between sleeve bearings (also called bushings or plain bearings) and ball bearings for a given application, one must consider several factors, including longevity, friction, noise, temperature, mounting, lubrication issues, cost and ease of installation and replacement. Each factor may be dependent on the quality of the machine in which the bearing type is used.

GGB sleeve bearings offer several advantages, including lower cost, less maintenance, greatly reduce noise at low speeds and easier installation. Sleeve bearing performance is also marked by a higher load capacity, specifically shock load resistance as a result of their greater contact zone. Assembly is simplified and longevity increased in sleeve bearings due to a straightforward press fit that eliminates bearing or housing damage. Sleeve bearings with a conformal liner also compensate for misalignment issues and vibration damping.

Additionally, low-friction plain bearings reduce housing dimensions and assembly weight and size by having a thinner profile.
