Centrifugal Clutch for the Public Works Industry

BLM Automatic Clutch was contracted by an OEM customer in the public works industry to manufacture a custom clutch.

BLM was required to meet exacting standards while preserving customer price criteria, as they were stepping in to produce the part after a previous supplier could no longer maintain an acceptable price point.

A flywheel mounted clutch and pulley system was required for an industrial sweeper application, with a mandatory 5 grove, 5V, 10″ pulley. This was not a problem for BLM, who was able to convert drawings of an existing pulley style clutch system into the part meeting the customer’s parameters.

Composed of steel and precision machined using state-of-the-art CNC lathes and milling equipment, the unit was assembled and finished with a coating of blue paint. The finished 8″ clutch met the space, size, and configuration requirements in the 150 HP sweeper with an idle RPM of 800 and operating RPM of 3000. 30 units were constructed after a turnaround time of 8 weeks and shipped to the customer in Japan. All products were fully dimensionally inspected for quality and accuracy. BLM is fully prepared to replace customer components with more cost effective solutions
