Industrial Power Transmission Pulley

The Tb Wood'S 5V553 is a quick detachable bushed bore V-belt pulley designed for industrial machinery and machine shop applications. It accepts bores from 1/2 in to 1-15/16 in and features three grooves for 5V and 5VX belt sections. This component suits maintenance engineers and plant operators who need reliable power transmission in heavy-duty equipment.

Sustained Load Performance

The 5.5 in pitch diameter maintains consistent belt engagement during continuous operation across 5V and 5VX profiles. Three grooves distribute the load evenly, reducing slippage when the drive runs at full capacity for extended periods. The quick detachable bushing allows the pulley to stay seated without fretting under constant torque.

Thermal Noise And Power Draw

Mechanical power transmission produces no electrical noise and draws no current of its own. The steel construction dissipates frictional heat through the hub and belt contact surfaces during normal use. No active cooling is required and the unit adds negligible thermal load to the drive system.

Questions about this item

How much heat does the 5V553 pulley generate when running all day?

The pulley itself produces negligible heat; any temperature rise comes from belt friction and the driven load, not from the 5.5 in pitch diameter sheave.

What shaft and bushing must I already have to mount this 3-groove pulley?

You need a shaft between 1/2 in and 1-15/16 in and a compatible Quick Detachable bushing that matches the pulley's bore specification.

Will the 5V553 work with older A or B section belts I keep in stock?

No, the 5.5 in pitch diameter is cut for 5V and 5VX belts only; A, B, 3V and other profiles are listed as not applicable.
