Clutch performance requirements: Complete separation, joint soft, moment of inertia of the driven part as possible, and heat dissipation.

Clutch bearing conditions: High-speed, high temperature, to withstand shock loads, low noise.

Separate bearing structure: Angular contact thrust ball or ball bearings can withstand greater structural type of axial load, a reliable sealing structure of high temperature grease to protect the clutch fill the demand conditions, and the unit automatically aligning diverse components of type for user selection.

Specific structure type: By separation into flat contact surface (TZ, TM) type, arc (RTZ, RTM) type, separated by aligning bearing unit is divided into non-aligning (WT, NT, NL type) and aligning (CTY, RCT, RCL type).
