BLM Automatic Clutch partnered with an engineering firm contracted by the U.S. Military to manufacture the 6", F60H clutch highlighted here. It was designed for use on a 21 horse power, 3600 RPM/1500 Idle chiller. BLM was responsible for all of the required work, which included the material sourcing and precision manufacturing. BLM's solution was chosen by this engineering firm as the best fit for their design as it exhibited maximum drive capability in a limited work space. State-of-the-art CNC lathes, milling machinery, and finishing equipment were utilized to mill and turn gray iron to the required profile, holding a tight ± 0.003" tolerance throughout. The unit was assembled, and subjected to a parkerizing phosphate plating process for corrosion and wear resistance, leaving the part with a black finish

800 units were produced in a 6 month period and shipped to the customer. BLM is a recognized leader in the manufacturing of centrifugal clutches for demanding applications, able to meet rigorous specifications. All products are fully dimensionally inspected and are held to the highest industry standards.

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.

An OEM manufacturer of compressors was in need of a solution for one of their products that had an issue starting in the cold weather. BLM was commissioned to manufacture a custom clutch to suit their demands, modifying a standard design to meet the specific needs of this customer. Utilizing advanced CNC milling and turning, a gray iron casting was used. A tolerance of ± 0.003" was maintained throughout and the unit was assembled and finished with a coating of blue paint. The produced 6" clutch would allow the engine to start and warm up before the compressor load was applied. Thorough dimensional inspection was implemented to ensure accuracy.

As requested, the compressor pulley was twice as large as the clutch pulley to facilitate the correct speed. The clutch is appropriate for the compressor's 18 HP engine, with an idle speed of 1600 RPM, and operating RPM of 3000. 30 units were produced in a turnaround time of 4 weeks, and shipped to the customer in Canada. This centrifugal clutch is suitable for multiple applications, and can be adapted to fit particular demands.

BLM Automatic Clutch was contracted to manufacture a custom centrifugal clutch for an OEM customer in the chemical industry. The client required an inline drive meeting specific alignment criteria in an industrial mixer application. The mixer was rated at a service factor of 3 due to its propensity to jam under load conditions. Taking all parameters into consideration, a stock coupling style design drawing was altered to meet the particular specifications outlined. Gray iron was precision machined using state-of-the-art CNC lathes, milling machinery, and other in house tools, which provided the precision necessary to achieve the required ± 0.003" tolerances. The unit was assembled and covered with a blue paint finish. The machined 6" clutch featured quick detachable bushings and is appropriate for use in applications up to 30HP and 1800 RPM.

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

BLM Automatic Clutch was contracted by an OEM customer in the City Waterworks industry to manufacture a custom clutch. Customer needed an alternate solution to the originally specified clutch. The OEM clutch required alignment to be maintained between the driven and drive side shafts. In use the clutch continually failed because of the inability to maintain alignment. BLM was able to offer a solution using a gear coupling which permits for misalignment and by modifying a design to fit the customer's space requirement.
