Tb Wood'S

Tb Wood'S 803C Quick Detachable 3 Groove V-Belt

SKU CH-AZYA-XWAQC

A quick-detachable, three-groove V-belt sheave with an 8 in C and CX pitch diameter

  • TypeSheaves & Pulleys
  • Quick-detachable bushing speeds up installation and removal
  • Three-groove design supports multiple C/CX belts for higher torque capacity
  • 8-inch C/CX pitch diameter matches standard drive requirements
  • Compatible with quick-detachable bushings for flexible bore sizing
  • New condition ensures full service life from first use

Industrial Power Transmission Component

The Tb Wood'S 803C is a three-groove V-belt pulley designed for use with C and CX belt sections in machinery drive systems. It features a quick-detachable bushed bore that accommodates shaft diameters from 7/8 in to 3-1/2 in for straightforward installation and removal. The cast construction suits heavy-duty industrial environments where reliable power transfer is essential.

Maintenance Teams and Plant Engineers

This pulley suits maintenance crews who need to replace worn sheaves on existing C-section belt drives without special tools. It is not for applications requiring A, B, 3V, 5V or other belt profiles, nor for setups that demand a finished bore or a different groove count. Operations using variable-speed or synchronous belts should select a different component.

C and CX Belt Compatibility

The single specification that determines fit is the belt trade size: this sheave accepts only C and CX V-belts with an 8 in pitch diameter. Using any other belt cross-section will prevent proper seating and torque transmission. Verify the belt markings on your drive before ordering to ensure the grooves match the belt profile exactly.

Questions about this item

Should I choose this 3-groove C/CX pulley or a single-groove version for my drive?

Choose the 3-groove 803C when the design calls for three C or CX belts side by side on an 8-inch pitch diameter; a single-groove sheave only accepts one belt and cannot share the load across multiple grooves.

What does the 8-inch C/CX pitch diameter mean once the pulley is mounted on a shaft?

The 8-inch pitch diameter is the effective diameter where C or CX belts ride, so it fixes the speed ratio and belt length calculation for the drive once the quick-detachable bushing locks the sheave to the shaft.

How does the quick-detachable bushing interface limit the bore range I can use?

The quick-detachable bushing system accepts standard QD bushings with bores from 7/8 inch to 3-1/2 inch, so the shaft diameter must fall within that range for the pulley to mount securely.
