Product Description
SWC65BH Universal Joint Coupling – Compact Lightweight Cardan Drive Shaft for Small Motor & Pump Transmission
The SWC65BH universal joint coupling is a compact, lightweight cardan drive shaft purpose-built for small-scale power transmission systems. Featuring a 65mm nominal bore and an exceptionally simple, space-saving structure, this small motor universal coupling delivers reliable torque transmission between misaligned shafts while maintaining minimal weight and footprint.
Engineered with metal flexible compensation, the SWC65BH cardan shaft absorbs angular misalignment without elastic elements, making it ideal for pump drives, small motors, compressors, and light industrial machinery where installation space is restricted and frequent maintenance access is required.
As a source factory manufacturer, Apexcoupling.com supplies the SWC65BH cross shaft coupling with full customization capability, abundant inventory, and fast global delivery.
