The Ogura Clutch Company was founded in 1938. Since that time, it has grown tobe the largest manufacturer of electromagnetic clutches in the world. Ogura has technical and manufacturing representation worldwide.Oguras numerous quality awards reflect a desire for continuous improvementwhich we apply not only to our products; but, also to our personnel. We believe the cornerstone of quality begins with people. This is why our personnel are continually trained on the latest manufacturing techniques and design principles. Most of our plants currently conform to ISO9001 and QS9000...

Selection For flow chart selection, choose the function you require. (You need to knowthe amount of torque required for the clutch or brake. Torque is a result ofinertia and acceleration time. If you do not know your torque or inertia, please go to Section 6 for help.) ST AR T - Clutches used to start a rotational load ST OP - Brakes used to stop a rotational load ST AR T/ST OP - Combination clutch/brake in packages used to both startand stop a load. (Individual clutches and brakes can also be used for this function.) HOLDING - Brakes to either stop a rotational load when power isreleased...

Custom molded gears can be supplied to suit your specific application. Clutch has the capability to drive clockwise or counterclockwise. > The MIC-N assembly includes a custom designed gear pulley to your specifications. The entire assembly is delivered pre-assembled, so it simply slides onto the shaft. There are no adjustments to make and no air gaps to set. The armature incorporates a one piece spring that eliminates backlash. > Special bushings allow for millions of operating cycles for most applications. > Bore of the clutch is made to fit a D-cut shaft to simplify installation and...

Using the stationary field design, the clutch fieldis mounted to the rotor with ball bearings. This provides easy installation and reduces maintenance requirements. Elimination of splines provide faster response and high performance by overcoming friction in the armature and hub. > The AM series clutches perform relentlessly yearafter year even in heavy duty applications,thanks to their excellent heat dissipation. By mounting the armature to its hub by means of leaf springs, backlash is minimized and armature rattle is eliminated. > Variations in acceleration or deceleration times and slip...

ELECTROMAGNETICCLUTCH BRAKE[ZERO BACKLASH] > FAST RESPONSE COMPACT DESIGN > TM series clutches and brakes are dry typesingle disk units with no sliding parts. That means you can count on fast response time. The compact design of the TM series reduces mounting requirements and makes installation a snap. NO BACKLASH ARMATURE MOUNTING FLEXIBILITY > By mounting the armature to its hub by means of leaf springs, backlash is eliminated as well as armature rattle. The TM series can be provided with a flange mount or bearing mount design. LOW INERTIA > Fast response and low inertia are due to the TM...

The CT clutches and the B series brakesinclude a patented adjusting mechanism for the armature that not only gives a constant adjustment for wear, but also produces a constant air gap on return. This gives a constant armature engagement time over the life of the unit which is critical in some cycling applications. The design of flutes in the armature helps to dissipate the heat generated by friction on engagement. > Armature to hub connection is via heavy duty spline. > Stainless steel hubs break up stray (flux) at the hub, preventing the magnetism from being transmitted into the shaft....

The MMC series utilize a special plate spring thatresists engine vibration and shock. Rotation may be clockwise or counterclockwise. > Efficient heat dissipation allows long life even in heavy duty applications. Clutch surface is tempered to provide effective rust protection. Mounting is a snap on these stationary coil type clutches. The coil is supported by a ball bearing. Alignment and maintenance are not required. > The compact design of the MMC series requires minimal space while providing high torque.
