Browning 2454817 Cogged V-belt AX77 79.2 in Oil Heat Resistant

Product Description

The BROWNING 2454817 is a cogged V-belt designed for industrial and commercial drive applications where heat and oil exposure are common service conditions. Sold under the Gripnotch style designation and identified as belt number AX77, this belt features a rubber construction with a cogged (notched) underside that improves flexibility, reduces heat buildup, and increases efficiency on smaller-diameter sheaves. The AX section profile measures 1/2 inch in width with an outside length of 79.2 inches and a belt pitch of 78.3 inches. It is rated for operating temperatures from -60 degrees F to 250 degrees F, making it suitable for demanding mechanical environments.

This belt is a direct fit for AX-section drive systems found in HVAC equipment, agricultural machinery, industrial fans, compressors, and general power transmission setups. The Gripnotch cogged profile is particularly well suited for variable-speed drives and drives with smaller sheave diameters where a standard wrapped belt would generate excessive heat or flex fatigue. Technicians servicing rooftop units, belt-drive blowers, or light industrial equipment will recognize the AX77 designation as a common replacement size.

Key Features

• Cogged Gripnotch profile reduces bending resistance and heat buildup on small-diameter sheaves
• Rubber construction with oil-resistant and heat-resistant properties for demanding drive environments
• Operating temperature range of -60 degrees F to 250 degrees F
• Outside length of 79.2 inches with a belt pitch of 78.3 inches
• AX section, 1/2 inch belt width — standard sizing for broad sheave compatibility
• Manufactured to RMA standards for consistent sizing and performance

Compatibility

Designed as an OEM-style replacement for AX77-designated cogged V-belt drive systems using standard AX-section sheaves. Verify sheave groove profile and center distance before installation.

Installation Notes

Belt installation should be performed by a qualified mechanic or technician familiar with power transmission drive systems. Always de-energize and lock out the equipment before removing or installing any drive belt. Never pry a belt over sheave flanges — adjust center distance to allow slack installation. After installation, verify belt tension and alignment per the equipment manufacturer specifications before returning the drive to service.
