SRD Series (Direct type )

Product photo
  • Economical model suitable for loads that have a flywheel effect, such as small power presses.
  • SR Clutches provide a single or integer revolution from the continually rotating outer race (drive side) to the inner race (load side) by simply pulling a lever.
  • SRD series is suitable for loads with a high moment of inertia like a press machine.
  • Torque range :24.5~147N・m

Features

  • ・Excellent responsiveness
    The mechanism provides outstanding responsiveness with a full cylindrical outer race inner face (drive side). The inner and outer races engage/disengage quickly when the lever is switched on or off.
  • ・Secure Engagement
    There is no slippage with the wedge-shaped rollers engaging between the inner and outer races.
  • ・Consistent stopping position
    The off (disengaged) position is always constant, so there are no cumulative stopping position errors.
  • ・Exceptional durability
    Long service life can be achieved as there are multiple rollers taking torque, less parts to wear between the components, and a high-precision finish.

Construction

SRD  Series
  • ・The SRD Series is mainly constructed of the following parts: inner and outer races, rollers, a trip cam cage, and a coil spring.
    (For SRD15, a spring pin is attached instead of a trapezoidal screw. )
  • ・When ordering, specify the inner race engagement rotation direction viewed from the arrow direction in the structural diagram. ※Right engagement (RH), Left engagement (LH)
