Continental Contitech 20042857 Cogged V-belt 5L 52 in

Product Description

The CONTINENTAL CONTITECH 20042857 is a fractional horsepower cogged V-belt designed for light-duty power transmission applications in HVAC, agricultural, and general mechanical equipment. Manufactured from high traction rubber, this belt carries the designation 5L520, indicating a 5L cross-section with a 52-inch outside length and a 50.80-inch internal length. The cogged construction reduces heat buildup, increases flexibility, and improves grip on smaller-diameter sheaves. Licensed technicians and general mechanics install this belt as a direct service replacement on equipment requiring a standard 5L-section fractional horsepower belt.

This belt is suited for residential and light commercial HVAC blower assemblies, fan drives, pump drives, and general power transmission systems that specify a 5L-section V-belt. The 5L520 designation is widely used across belt-driven equipment where a fractional horsepower drive is standard. Its abrasion-resistant and ozone-resistant compound makes it appropriate for both indoor mechanical rooms and outdoor equipment installations. Consult the driven equipment nameplate or service manual to confirm the correct belt section and outside length before installation.

Key Features

• Cogged design improves flexibility and reduces heat buildup on small-diameter sheaves
• High traction rubber compound provides reliable grip under load
• Abrasion resistant and ozone resistant for extended service life in varied environments
• Wide operating temperature range: -40 degrees F minimum to 284 degrees F maximum (based on -40 C to 140 C rating)
• Belt number 5L520 — 5L section, 52-inch outside length, 50.80-inch internal length
• Fractional horsepower V-belt style for light-duty drive applications

Compatibility

Designed as a standard replacement for equipment specifying a 5L-section fractional horsepower cogged V-belt with a 52-inch outside length. Verify belt section, outside length, and internal length against the OEM drive specification before ordering.

Installation Notes

Mechanical technicians and HVAC service professionals install this belt as part of routine drive maintenance. Always de-energize and lock out the equipment before removing the old belt or installing the new one. Do not pry the belt over sheave flanges with tools that could damage the belt cords — use proper sheave alignment and tension adjustment to seat the belt correctly. Confirm sheave alignment and belt tension with a tension gauge or deflection method per the equipment manufacturer's specification after installation.
