Product catalog summary

Overview: This document provides technical specifications and guidelines for Cage Freewheels SFB, which are used as backstops, overrunning clutches, and indexing freewheels. These components are designed to be installed between customer-supplied inner and outer rings and are suitable for various industrial applications.

Specifications: The Cage Freewheels SFB are sprag freewheels with nominal torques up to 2,070 Nm. They are available in various sizes, each with specific dimensions and torque capacities. The document lists several models, such as SFB 22-10 J, SFB 27-13.5 J, and SFB 103-16 J, along with their respective dimensions and weights.

Mounting Instructions: The lateral guidance of the Cage Freewheels can be achieved using a shoulder on the outer ring or guard rings/discs fixed in the outer ring. Torque transmission capacity can be increased by arranging multiple cages side by side, for which consultation with RINGSPANN is recommended.

Ordering Information: An example is provided for ordering a standard type freewheel, such as SFB 44-16 J. The document emphasizes the importance of ideal concentricity between the inner and outer rings for achieving the theoretical nominal torque.

Key Data from Tables: The tables provide detailed specifications for each model, including nominal torque, dimensions (J, D, B, K), and weight. For instance, the SFB 79-25.4 J model has a nominal torque of 2,070 Nm, dimensions of 79.698 mm (J), 96.363 mm (D), 25.4 mm (B), and weighs 0.20 kg.

Recommendations: The document advises consulting page 114 for technical points regarding sprag tracks and page 14 for determining selection torque. It also highlights that the maximum transmissible torque is twice the specified nominal torque.
