UNMARKED SK 1V -QD BUSHING

Description:

The UNMARKED SK 1V QD Bushing is used in industrial power transmission systems to securely mount pulleys, sprockets, and sheaves onto rotating shafts. Commonly installed in conveyor systems, pumps, fans, compressors, and material handling equipment. Maintenance teams and system integrators use this part for repair, retrofit, or replacement of worn or damaged shaft mounting bushings in industrial machinery.

Applications:

The UNMARKED SK 1V QD Bushings are used in industrial equipment requiring a secure and removable shaft-to-hub connection. They are commonly found in conveyor drives, HVAC systems, pumps, fans, mixers, crushers, and packaging machinery where pulleys, sheaves, or sprockets must be mounted to rotating shafts. The SK series quick detachable design provides high torque transmission, simplified installation and removal, and reliable performance in demanding industrial environments. SK bushings are precision-machined tapered bushings that are fully split on one side, allowing easy mounting and removal while maintaining accurate shaft alignment and strong clamping force.
