The MC5 mini clutch from Ogura Industrial Corporation incorporates zero backlash curved armature springs. The curved armature spring design allows for force to be transmitted across the arc of the spring. This allows greater armature travel while keeping a smaller attachment diameter verses a straight leaf spring design. This smaller diameter allows customers to use smaller gears or pulleys in their application without having to go to an intermediate adaptor flange.
The MC5’s are available either with or without ball bearings depending upon application speed and vibration requirements. Clutches are available in two torque options of 4.5 in.-lbs and 9 in.-lbs. The ball bearing units can operate up to 3,600 rpm, but higher speed modifications are possible. Clutches come standard with lead wires that are UL/CSA certified and both sizes are RoHS compliant.
