Key Features

Raw Edge Cut Construction

Raw edge cogged belts do not use textile wrapping on the outer surface. Instead, they are manufactured by slitting individual belts from a rubber sleeve, which is why they are also referred to as cut edge belts. This manufacturing method improves belt flexibility and power transmission efficiency.

Molded Cogged Underside

The belts feature molded cogs on the underside, which significantly reduce bending resistance. This allows the belt to operate efficiently on pulleys with approximately 20% smaller diameters compared with conventional wrapped belts.

Reduced Mechanical Losses

Lower bending resistance during operation reduces mechanical energy losses during belt flexing. This leads to improved transmission efficiency and lower operating temperatures.

Improved Heat Dissipation

Heat dissipation is enhanced due to the larger surface area between the belt and surrounding air. Additionally, air turbulence created around the cogs during operation further improves cooling performance.

High Speed Ratio Capability

These belts support speed ratios up to 1:12, which allows certain multi-stage drive systems to be simplified or eliminated, improving system efficiency and reducing mechanical complexity.

Durable Multi-Layer Construction

The belts are constructed using:

• Special top fabric layer for protection

• Tough tensile members for increased strength

• Polychloroprene cushion rubber compound

• Fiber-filled polychloroprene base compound

This combination provides excellent durability and reliable power transmission.

High Tension Capability

Raw edge cogged belts generally require higher operating tension compared to wrapped belts. This higher tension allows the belts to achieve greater power transmission capacity in demanding drive systems.

Reliable Performance in Harsh Conditions

The belts are designed to be antistatic, oil-resistant, and heat-resistant, ensuring reliable performance in industrial environments.

Operating temperature range: –18°C to +100°C
Maximum recommended belt speed: 30 m/s

Applications

Realshow Raw Edge Cogged V-Belts are widely used in industrial drive systems where higher efficiency and compact drive layouts are required.

Typical applications include:

• Industrial machinery

• High-speed mechanical drives

• Drives with small pulley diameters

• Systems operating at high ambient temperatures

• High power transmission equipment

• V-flat drive systems

• Machinery using reverse idlers

These belts are also commonly used as replacement belts in industrial drives where wrapped belts may not provide sufficient performance.
