  • TypeSheaves & Pulleys
  • Fits 5V and 5VX belts at 12.5 in pitch diameter
  • Two grooves transmit higher torque on compatible drives
  • Quick-detachable bushing allows fast shaft mounting and removal
  • Cast-iron construction resists wear in industrial power-transmission
  • Bore range 1/2 in to 2-15/16 in suits many shaft sizes

12.5 in 2-Groove Quick Detachable Sheave

This cast iron sheave provides a 12.5 in pitch diameter for 5V and 5VX V-belts. It uses a Quick Detachable bushing system that accepts bore sizes from 1/2 in to 2-15/16 in. The two-groove design suits power transmission drives requiring dual belt tracking. Gray finish resists corrosion in industrial environments.

Quick Detachable Bushing Upgrade

Replaces fixed-bore sheaves that require exact shaft matching or press fits. The Quick Detachable hub allows rapid installation and removal without special tools, reducing downtime during belt changes or alignment checks. The jump is worth it when shafts vary across equipment or when frequent drive reconfiguration is needed. Cast iron construction handles standard shock loads in conveyor and fan drives.

Maintenance Teams Needing Fast Swaps

Suits maintenance crews who standardise on QD bushings to cover multiple shaft sizes with one sheave stock. Not for drives requiring more than two grooves or pitches other than 5V and 5VX. Buyers needing lighter weight or non-metallic materials should look at alternative sheave types. Single-groove applications are also outside this model's scope.

Highlights

  • Fits 5V and 5VX belts at 12.5 in pitch diameter
  • Two grooves transmit higher torque on compatible drives
  • Quick-detachable bushing allows fast shaft mounting and removal
  • Cast-iron construction resists wear in industrial power-transmission
  • Bore range 1/2 in to 2-15/16 in suits many shaft sizes
