Engine rooms and deck machinery in all types of vessels have benefited from Wichita and Industrial Clutch’s expertise and experience in marine clutches and brakes. Wichita marine clutches and brakes are both consistent and reliable with pneumatic control through the Wichita airtube providing the straight-line characteristics of torque versus pressure, allowing smooth accurate power take up with no effects from centrifugal force. The special ventilated design of Wichita marine clutches provides the ability to dissipate the high heat generated in maneuvers such as crash astern or holding on station.

Water-cooled brakes provide the ideal solution for high-energy dynamic braking duties.

Here are some of the reasons why:

• Large friction area provides good control even in arduous start up conditions
• Clutches and brakes are available in 1,2,3 or 4 plate designs to suit torque, heat,
  response and space requirements.
• Pressure engaged, spring engaged or dual acting brakes suit operational requirements/li>

The Wichita and Industrial Clutch family of oil immersed clutches and brakes are ideal for the marine market. Fully enclosed or designed for mounting internal to gearboxes these units are immune from environmental conditions. Since torque is created through hydro viscous shearing of the oil, clutch and brake plate life is almost infinite. Special grooving patterns and friction materials offer smooth engagements with excellent heat dissipation and can be used in a variety of oils including vegetable based and EP oils. Available in air or hydraulic actuation.

Wichita Clutch Marine Low Inerita Clutch Designed for marine propulsion applications, the Wichita Air-Tube Disc Clutch combines all the best features of the disc type clutch with all the advantages of the direct air engagement Units engage smoothly without noise, shock or imapct and release completely in a fraction of a second due to small volume of air required. Centrifugal blower design dissipates heat generated by controled slipping or high cycle rate operation Large friction area provides good control even in arduous start up conditions This air-applied clutch is available in 1,2,3 or 4 plate designs to suit torque, heat, response and space requirements Wichita Clutch Standard Vent Clutch Large friction area for high energy smooth controlled start-up Air applied clutch with full circle 1,2, 3 or 4 disc design to suit various shaft diameters speed and torque requirements Quick change ring design option provides: - easy maintenance - smooth controlled engagement Unaffected by centrifugal force, these Marine Clutch units are custom built to satisfy marine classification society requirements. Designed for high inertia loads such as main propulsion drives where smooth controlled starts are needed. The SV is suitable for through-shaft or in line shaft-to-shaft mounting. Best suited as a coupling clutch to connect two shafts Wichta Clutch Kopper Kool™ Brake The KK is designed for high-energy continuous slipping applications. It is suitable for end-shaft or through-shaft mounting Water-cooled brake with the cooling water contained within water jackets Copper plates quickly transfer the heat away from the friction surfaces to give good control and long life The friction surfaces are dry running Air applied brake with full circle friction discs Air and water connections are stationary Wichita Clutch AquaMakks Water Cooled Clutch/Brake Air, hydraulic, or spring set actuated and water cooled design, featuring copper wear plates optimized for heavy-duty continuous slip tension applications AquaMaKKs™ consist of a series of alternating friction discs and water jackets. Torque is transmitted by applying axial force from the pneumatic, hydraulic, or spring set actuator. Copper wear plates are used for excellent heat dissipation AquaMaKKs provides accurate torque control for constant tensioning and are perfectly suited for marine deck machinery applications Wichita Clutch Kopper Kool™ Spring Set Brake/Clutch For high-energy continuous slipping applications such as dynamic tensioning duties where 'fail to safety' is required. The KK/SS is suitable for end-shaft or through-shaft mounting Available in two actuation options: a) KK/SS - Spring applied / air released 'passive brake' for emergency engagement in the event of air supply failure b) KK/SS/Dual acting - A brake combining the advantages of excellent air applied 'active' control plus the added security of spring applied 'passive' holding and stopping action Water-cooled brake with the cooling water contained within water jackets Copper plates quickly transfer the heat away from the friction surfaces to give good control and long life The friction surfaces are dry running Air and water connections are stationary Industrial Clutch Heavy Duty Air Set LKM Clutch Designed for marine propulsion applications, the Industrial Clutch model LKM Clutch is a robust multi-plate design intended for use with reduction gearboxes Internal and external plate separation prevents drag of the plates during the disengaged mode The outboard quill bearing offers added support on reduction gearboxes Designed with an integral rotary air union and simple oring/piston actuation chamber Available in 2, 3 and 4 plate configurations Industrial Clutch Oil Immersed HBA Brake The model HBA Brake is an oil immersed, air or hydraulic actuated design intended to be mounted on a drive train shaft extension. Using hydro viscous shearing of the oil and forced oil lubrication the HBA offers outstanding life using the same oil as the gearbox equipment Special grooving patterns and materials in the plates allow for tremendous heat dissipation and smooth engagements. Vegetable based oils and EP additives can be used with out any detrimental effects to the brake friction material Fully enclosed, the HBA is protected from outside environmental concerns and is free from dust, sparks or moving components Industrial Clutch Oil Immersed HC Clutch The model HC clutch is an oil immersed, air or hydraulic actuated clutch designed for use internal to a customers gearbox Using hydro viscous shearing of the oil and forced oil lubrication the HC offers outstanding life using the same oil as the gearbox equipment. Hardened hubs and extra wide plates reduce spline stresses associated with multi plate designs Special grooving patterns and materials in the plates allow for tremendous heat dissipation and smooth engagements. Vegetable based oils and EP additives can be used with out any detrimental effects to the brake friction material Hydraulic actuated units incorporate a patented balance chamber design the eliminated centrifugal engagement and allows for smooth reliable release of the clutch Air actuated units are also available as well as dry running friction designs for custom applications Twiflex Limited Model VMS2 Caliper Disk Brake Spring-applied, hydraulically released modular disc brake can be used for aircraft platform lifts, ship deck equipment including hoists, winches and cranes Braking force is widely adjustable by means of shim packs which determine the total amount of spring compression.
