Sleeve bearings minimize friction between shafts and machinery parts. The sleeve bushings below are unflanged for tight spaces, and feature the renowned self-lubricating FrelonGOLD® liner that allows maintenance-free linear and rotational movement and vibration dampening. They excel in harsh, dirty, shock-loaded, or high-temperature environments (-400°F to +400°F). The part numbers in this unflanged category are PS (inch) and PSM (metric).
