This model features a large number of sprags controlled by two concentric cages.The transmitted torque is high compared to the required space.
Sprags are synchronised by the double cage design, and individually energized by a special spring.
In addition to the DC series offered in this catalogue, the CSK, GFK, and RSBW ranges use a similar principle.
