The Timken Company - SU-6 Type Complete Couplings - Inch (Imperial) Bores

Batch CAD Cart (0) ▾

The SU Type coupling has a single flex plane, and is comprised of a single disc pack kit with two hubs. It is suitable for angular and axial misalignment only. Two SU couplings are often combined with a shaft to make a floating shaft coupling. The shaft can be hollow for long light weight floating shaft couplings.
