Description
The Gates 4/B128 is a four-rib B-section Gripband V-belt engineered for demanding multi-belt drive applications in HVAC, industrial, and commercial equipment. With a 131-inch outside length, this banded belt keeps multiple ribs operating as a single unified unit, eliminating belt rollover, whipping, and turnover — common failure modes in high-torque or pulsating-load applications.
What Is a Gripband Belt?
Gripband belts feature a reinforced tie-band that joins multiple classical V-belt ribs together. This construction provides the combined pulling power of several individual belts while maintaining precise alignment across the full width of the sheave. The result is smoother power transmission, reduced vibration, and extended drive life compared to matched sets of individual V-belts.
Key Features
- Four-rib banded construction for superior stability and anti-rollover performance
- B-section profile for compatibility with standard B-groove sheaves and pulleys
- 131-inch outside length (4/B128 designation)
- High-strength tension cords for excellent load-carrying capacity
- Oil- and heat-resistant rubber compound for extended service life
- Engineered to replace matched sets of four individual B-section V-belts
- Reduces vibration and noise in multi-belt drive systems
- Suitable for HVAC blower drives, fans, compressors, and industrial equipment
Application Suitability
The 4/B128 Gripband belt is ideal for HVAC air handlers, rooftop units, centrifugal fans, and blower assemblies that require multi-belt drive configurations. It is also widely used in agricultural, industrial, and commercial equipment where belt stability under variable or shock loads is critical.
