High-Torque Sleeve Couplings
 |
With a steel sleeve and hubs, these transmit higher torque than other sleeve couplings. Lubricate to reduce friction between the teeth on the hubs and the grooves on the sleeve. For a complete coupling, select two hubs, one sleeve, and one seal kit. Choose components of the same trade size to ensure they'll fit together.
Hubs
 |
The metal body mounts onto shafts to transmit torque from one shaft to the other through the flexible center.
Steel—Best for dry environments, since moisture will cause these hubs to rust.
Press-Fit Shaft Mount—Apply heat to expand these hubs slightly and fit them onto the shaft. They shrink as they cool to form a tight grip on the shaft.
