Product Overview: Complete Freewheels FA with lever arm are designed with sprags and grease lubrication, suitable for applications as backstops or indexing freewheels. They are maintenance-free due to grease lubrication and are available in a standard type and a RIDUVIT® type for extended service life.

Specifications: The freewheels offer nominal torques up to 2,500 Nm and bores up to 85 mm. Various standardized bore diameters are available with short delivery times. The maximum transmissible torque is twice the nominal torque.

Mounting Instructions: When used as a backstop, the lever arm supports the backdriving torque and must have 0.5 to 2 mm play in axial and radial directions. As an indexing freewheel, the lever arm acts as the indexing lever. The shaft tolerance must be ISO h6 or j6.
