DC Sprag Freewheels — Sizes & Specifications

The DC series is a sprag-type freewheel insert: a cage of precision sprags that fits between plain inner and outer races in your own housing design, giving indexing, backstopping or overrunning in a very compact space. DC inserts are used in conveyor drives, packaging machinery and agricultural equipment. BPK supplies the DC range listed here, factory-direct from Yandian, Shandong, for importers, distributors and OEM buyers.
