Custom Centrifugal Clutches

At BLM Automatic Clutch, we have been providing our customers with custom centrifugal clutches for over 80 years.

Regardless of application, our experienced team can provide the correct clutch configuration to meet your specific requirement. We offer various coupling, flywheel, universal shaft, pulley, and soft start combinations.

Coupling combination options include close shaft mounting, gap mounting, and gear coupling configurations. Flywheel mounting options include directly coupling, type FMU for use with universal shafts, and flexible element arrangement, which is particularly useful when dealing with torsional vibration issues.

Universal shaft combinations include Type E for use with a Spicer shaft in heavy duty applications, or Type HMU universal joint.

Multiple pulley styles including integral sheave, timing pulleys, step pulleys, single pulleys, double pulleys, and flywheel mounted pulley can be utilized, depending on the design requirements of the equipment. Soft start combinations include the double “C” flange designed for use between the motor and reducer, or its metric counterpart, the “D” flange.

Clutches can be designed to work with either gas or electric motors from 1 to 3,000 horsepower and can vary from 3 to 30 inches in diameter. Finished products can be either painted or plated per customer’s specifications. Our centrifugal clutches can be found in pumps, mortar mixers, augers, power trowels, compressors, saws, kilns, and more. We offer maintenance, repair, and warranties on all of our products.
