A customer in the mining industry needed an inline clutch to work within a limited space coal crusher application.
BLM was selected to develop a high-performance replacement for an OEM product that was exhibiting a high failure rate. Adapting a drawing from their portfolio of over 4000 drawings, the unit was constructed using gray iron and BLM’s advanced machining capabilities. This included engine lathes, Milling machines, and other machine shop tools and processes. The unit was turned and milled holding a tight ± 0.003″ tolerance.
The part was assembled and finished with a blue paint coating. Full dimensional inspections were carried out during production to ensure quality and integrity.
The resulting 18″ clutch featured a bushing on the driven side and bored to suit on the drive side, as specified for the 125 HP, 700 operating RPM application. Turnaround time for the centrifugal clutch was 12 weeks, and 2 were produced for shipment to the customer. BLM is prepared to work with customers to provide customized solutions to their demanding applications, with focus on high quality and cost effectiveness.

Project Scope
Project Scope
The customer required an inline clutch with space limitations. The previously installed clutch failed after 2 years use due to incorrect specification. BLM initially worked with the OEM but did not win the original order because our custom designed clutch took longer to produce than the off-the-shelf solution the OEM originally settled on. When this clutch failed the OEM contacted BLM to resolve the problem
