S Series

Stationary Cylinder for Precise Alignment

S Series

Typical S Series Clutch

 

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

S Series Image

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.

Logan Outperforms Electromagnetic Clutches

View of a modified standard Logan S 300 Series clutch (right) which replaced an Ortlinghaus style electromagnetic clutch (left). The clutch, drive cup and disc pack were modified on the Logan S300 to fit within the existing Electromagnetic clutch envelope.Logan has the design and manufacturing capability to replace existing and obsolete electromagnetic clutches with Logan technology.

 

Logan vs. Electromagnetic Clutches

  • Transmits more Torque and has higher RPM
    capabilities within the same envelope

  • Eliminates residual DC magnetism in disc packs
    and bearings-reduces downtime
  • Disc Pack, Bearing Kits and Seal Kits for LoganSide view showing identical axial length, and 3-Disc Pack configuration of the Logan S300 and Ortlinghaus Style Clutch.clutches are available from stock
