CSK One-Way Bearings — Sizes & Specifications
The CSK series is a one-way (freewheel) clutch bearing: it drives in one direction and freewheels in the other, in a unit the size of a standard ball bearing. The PP version adds a keyway on both rings for positive location. CSK clutches handle indexing, backstopping and overrunning duty in conveyors, packaging and printing machinery. BPK supplies CSK8 to CSK62, factory-direct from Yandian, Shandong, for importers, distributors and OEM buyers.
