  • Copper disc design for high heat dissipation
  • Accurate control
The Wichita Kopper Kool airtube disc Clutches and Brakes are liquid cooled and consist of a series of alternating discs connecting an inner drive member to an outer drive member.

Engagement is achieved by pneumatic expansion of the airtube. This air-operated clutch contains copper discs for excellent heat dissipation and provides an accurately controlled continuous slip action for constant web tensioning. Tension levels are in direct proportion to air pressure applied.

Note

N/A Maximum water jacket inlet pressure is 60 PSI. Brakes with as great as 50 % higher torque capacity is available upon request.

For mounting, use socket head capscrews conforming to the ASTM-574-97a.
Current design is for intermittent duty applications. Such as, anchor, mooring, take-up and traction type winch applications.
