Keyless Locking Assemblies

A single taper design better equipped to handle the bending moment present in pulley applications.

The standard in keyless locking assemblies is the RBL, it is self-centering, and no pilot bushing is needed. The single taper design is better able to handle the bending moment present in pulley applications. For high-tension applications, Precision Pulley & Idler recommends the RBM and the RBH. The graphic shows the relative difference in size and bending moment for each series.
