Quick Detachable Bushed Bore

The Tb Wood'S 443B is a new cast iron v-belt pulley with three grooves and a 4.75" outside diameter. It accepts a Quick Detachable SH bushing covering a 1/2" to 1-5/8" bore range for fast installation or removal on power transmission shafts.

Belt Capacity and Pitch Diameters

The sheave handles 4L, 5L, A, AX, B and BX belt sections with corresponding pitch diameters of 4 in for A and AX types and 4.4 in for B and BX types. It does not support 3L, 3V, 3VX, 5V, 5VX, C or CX profiles, limiting its use to light and medium duty classical and narrow belt drives.

Bushing Interface Constraint

Mounting relies on the Quick Detachable SH bushing standard, so the shaft must be prepared for that specific taper and keyway configuration. Without a compatible SH bushing the pulley cannot be secured, and no other bushing series will fit the hub.

Questions about this item

Will this 4.75" OD pulley work with my existing SH bushing?

Yes, the 443B is designed for SH quick-detachable bushings, so it mounts directly onto any standard SH bushing you already use.

How can I verify the pulley is running true after installation?

Check for smooth rotation and minimal wobble at speed; the cast-iron construction and precision-machined grooves keep A, AX, B and BX belts tracking steadily at the listed pitch diameters.

Does the package include the SH bushing and mounting hardware?

Only the three-groove cast-iron sheave is supplied; the SH bushing, set screws and keys must be purchased separately.
