Product identity

The TB Woods 2BK40 is a quick-detachable bushed pulley designed for industrial power-transmission drives. It accepts a split-taper bushing with a 1/2 in to 1-1/2 in bore range and provides two grooves for compatible V-belts. Maintenance teams and machine builders use it to mount and remove belt drives without specialised tools.

Belt compatibility

This pulley supports 4L, 5L, A, AX, B and BX belt sections with pitch diameters of 3.2 in for the A-series sizes and 3.6 in for the B-series sizes. The 3L, 3V, 3VX, 5V, 5VX, C and CX sections are not applicable. Selecting a belt outside these trade sizes will prevent correct engagement.

Build integration

The split-taper bushing mounts the pulley securely on shafts within the stated bore range and allows rapid removal for service or ratio changes. Two grooves enable dual-belt drives for higher torque capacity while the quick-detach design frees up maintenance time. Shaft keyway dimensions and bushing hardware must match the installation requirements.
