S Series

Stationary Cylinder for Precise Alignment

The actuating cylinder and piston in the S series design do not rotate. They are bearing sup-ported on the mounting hub and are held stationary by the external connection to the inlet port. This bearing allows the separator discs and hub, and the shaft on which it mounts, to rotate about the cylinder and piston. A thrust bearing permits relative motion between the stationary piston and rotating separator discs. Because both bearings require lubrication, it is important to utilize lube ports provided and/or direct an oil spray or splash at bearing surfaces.

Hydraulic / Pneumatic Clutch for Wet Operation

Operation: Pressurizing the cylinder with fluid or air forces the piston to clamp and lock the friction and separator discs, and release springs. Torque is transferred through the clutch to the drive cup. When pressure is removed, the release springs separate the separator and friction discs and maintain a running clearance between separator and friction disc surfaces. Torque ratings are based on wet operation.

Lubrication: S Series clutches and brakes are designed primarily for wet operation within gearboxes and transmissions. They can be partially submerged in an oil sump or an oil splash or spray can be directed at disc pack and bearing surfaces. Lube ports are also provided on some models.
