Ultra-High-Torque Flexible Shaft Couplings
 |  |
(Each Component Sold Separately) |
With a rigid gear design, these steel couplings transmit more torque than other couplings of the same size. Lubrication is required. To install, heat the hubs to expand them slightly and fit them onto the shaft. When they cool, hubs shrink to fit the shaft tightly.
A complete coupling consists of two hubs, one sleeve, and one seal kit (each component sold separately).
