  • Designed for C and CX belts with 12 in pitch diameter

  • Three grooves distribute load across multiple belts
  • Cast iron construction resists wear in power transmission
  • 40 in outside diameter suits standard drive layouts

Quick-Detachable 3-Groove Pulley

The Tb Wood'S 1203C is a cast-iron V-belt pulley with a 12.40-inch outside diameter and three grooves for C and CX belt sections. It uses a quick-detachable bushed bore that accepts shaft sizes from 7/8 inch to 3-1/2 inch. The grey finish suits industrial power-transmission drives.

Replaces Fixed-Bore Pulleys

Swapping a fixed-bore pulley for this bushed model removes the need to match the bore to a specific shaft diameter. The change is worth it when shafts differ across equipment or when faster pulley changes reduce downtime during maintenance.

Fits C and CX Belt Drives

The pulley mounts on a standard quick-detachable bushing, so the same hub can serve multiple shaft sizes within the stated range. It frees the designer from stocking separate pulleys for each shaft diameter in a C-section drive line.
