In-Line Slip Clutches feature low-backlash operation.

April 17, 2014

Featuring all-mechanical design, Slip-Ease® S98CA7 Multi-Plate Clutches are commonly used for overload protection to prevent injury and machine failure. Slip plates are layered with friction pads, and adjusting nut sets slip torque by squeezing plates together. Outer plates are tabbed to fit into output housing and inner plates are connected to input hub, so that ends disengage from one another upon slipping. Compared to standard clutches, Slip-Ease models offer reduced backlash of about 2°. Read More
