日本ウイチタ Product Lineup

The "Kopper Kool" we handle is a water-cooled brake that encapsulates cooling water within a water jacket. It is available in two operating options: "KK/SS" and "KK/SS/Dual Action." The KK/SS is suitable for mounting on end shafts or through shafts. The friction surface operates in dry running, and the copper plate quickly dissipates heat from the friction surface, achieving excellent control and long lifespan. 【Features】 ■ Encapsulates cooling water within the water jacket ■ Friction surface operates in dry running ■ The copper plate quickly dissipates heat from the friction surface, achieving excellent control and long lifespan *For more details, please refer to the PDF materials or feel free to contact us.

"AquaMakks" is a water-cooled clutch and brake designed to provide precise torque control for heavy-load tension applications. It is controlled by pneumatic or hydraulic means and is water-cooled. It consists of a series of friction discs and a water jacket arranged alternately. Torque is transmitted by applying axial force from pneumatic, hydraulic, or spring-set actuators. 【Features】 ■ Achieves top-class thermal capacity with a water channel that ensures balanced water flow ■ Long-lasting friction materials that minimize wear on the opposing copper ■ High thermal transfer capability due to copper alloy wear plates ■ Perfect alignment of rotating discs enabled by hub splines ■ Complete release guaranteed by a release spring ■ Easy wear adjustment by simply removing shims without disassembling the unit *For more details, please refer to the PDF document or feel free to contact us.

The "LI/SSB" is a low-inertia spring-set brake designed for periodic and general stopping and holding operations with a "fail-to-safety" design. It features an air-release brake with spring application and full-circle friction discs, designed for end shaft or through shaft mounting. Additionally, the start/stop parts have low inertia, which shortens deceleration time and increases the number of cycles per minute. 【Features】 ■ "Fail-to-safety" design ■ Air-release brake with spring application and full-circle friction discs ■ Available in designs with 1, 2, 3, or 4 plates, with three spring ratings to suit individual application requirements for torque, heat, space, etc. ■ The start/stop parts have low inertia, reducing heat generated during dynamic braking conditions. *For more details, please refer to the PDF materials or feel free to contact us.

The "LIB" is a low-interior clutch designed for end shaft or through shaft mounting. It features an air brake with a full circumference friction disk, and designs with 1, 2, 3, or 4 plates are available to meet torque and space requirements. Additionally, the start/stop parts have low inertia, which reduces deceleration time and increases the number of cycles per minute, while also reducing the heat generated during dynamic braking conditions. 【Features】 ■ Designed for end shaft or through shaft mounting ■ Air connection part is fixed ■ Air brake with a full circumference friction disk ■ Start/stop parts have low inertia, reducing heat generated during dynamic braking conditions *For more details, please refer to the PDF document or feel free to contact us.
