Overview
The Martin 65V1130E QD sheave is a heavy-duty, six-groove quick disconnect pulley engineered for 5V belt systems. With a 11.3-inch outside diameter and E-series bushing interface, this sheave delivers reliable performance in industrial power transmission applications. Quick Disconnect mounting eliminates the need to slide the pulley on and off the shaft, reducing downtime during maintenance and belt changes.
Key Features
- Quick Disconnect (QD) Design: The removable tapered bushing locks the sheave to the shaft with cap screws, enabling rapid installation and removal without shaft manipulation.
- 6-Groove Configuration: Accommodates six 5V belts for load distribution and consistent drive performance in moderate to heavy-duty applications.
- 5V Belt Section: Optimized for narrow-wedge V-belt drives commonly found in pumps, compressors, fans, and machine tools.
- E-Series Bushing Compatibility: Accepts Martin E-series QD bushings with bore ranges from 1 inch to 2.875 inches, providing flexible shaft mounting options.
- Standard Industry Dimensions: 4-7/16-inch face width and 11.3-inch outside diameter ensure compatibility across common industrial equipment.

Typical Applications
This 65V1130E sheave is used in agricultural machinery, HVAC equipment, industrial fans, pump drives, air compressors, conveyor systems, and light-to-medium industrial power transmission. The 5V belt section is ideal for applications requiring efficient torque transmission without excessive belt tension.
Compatibility & Replacements
Compatible With
- Martin 5V belt drives and multi-belt systems
- Standard industrial shaft diameters 1″ to 2.875″
- Equipment using Martin E-series QD bushings
- Systems requiring 6-groove fixed-diameter sheaves
Replaces / Drop-In Replacement For
Martin sheaves are interchangeable with other manufacturers’ sheaves and bushings. Verify exact cross-reference compatibility with your distributor before ordering, as groove count and belt section must match your existing drive system.
Works With
- Martin QD bushings (E-series: SH, SK, SL, SM, SN, SP)
- Standard 5V V-belts (Gates, Continental, Bando, etc.)
- Conventional shaft key and keyway systems
- Static and dynamic balancing procedures
