Precision Polyimide Crowned Bearing for Cleanroom & Semiconductor Equipment

Precision Crowned PI Bearing for High-Performance Motion Systems

This miniature crowned outer ring bearing is manufactured from high-performance polyimide (PI) and equipped with zirconia ceramic balls. The crowned profile helps reduce edge stress, improves tracking performance, and compensates for slight misalignment during operation.

Designed for semiconductor equipment, cleanroom automation, precision positioning systems, and high-temperature applications, this bearing offers excellent wear resistance, electrical insulation, low particle generation, and long service life.
