INA Sprag Clutch Bearing 4 mm ID 8 mm OD 8 mm Race Width HFL0408-KF-A-L564

INA HFL0408-KF-A-L564 Sprag Clutch Bearing is a precision drawn cup roller clutch featuring a 4 mm inner diameter, 8 mm outer diameter, and 8 mm race width. This compact one-way clutch is designed to transmit high torques in one direction while maintaining a low radial profile, making it suitable for a variety of industrial applications including indexing, back-stopping, and overrunning clutches.

The bearing assembly includes a thin-walled drawn outer ring with internal ramps, plastic cages, pressure springs, and needle rollers. This combination provides precise indexing through individual spring-loading of the needle rollers, ensuring continuous contact and enabling high-frequency operation with minimal inertia.

Engineered for efficiency, the HFL series includes an integral plain or rolling bearing arrangement that supports both torques and radial forces. This reduces maintenance requirements, lowers heat generation, and minimizes operational noise, leading to overall lower operating costs.

Manufactured in Germany by INA, part of Schaeffler Group, the product underscores a reliable standard of quality in mechanical components. While this model does not carry specific formal certifications or approvals, it is widely applied in mechanical, fluid power, and tool assemblies requiring dependable rotary bearing solutions.

Key features include durability derived from robust materials and design optimized for industrial environments such as manufacturing, construction, and machinery maintenance. The sprag clutch bearing is especially beneficial where precise motion control and directional locking are necessary.
