Overview
The ContiTech A42 classical V-belt is a proven power transmission component engineered for demanding agricultural and general industrial machinery applications. Built with a wrapped construction and reinforced polyester cord, this A-section belt delivers consistent friction grip and wedging action in sheave grooves. The A42 excels in compact drive systems operating at higher speeds over small-diameter pulleys and short center distances.
Key Features
- Wrapped Classical Construction: Suitable for demanding drives in all sectors of machine engineering, with robust durability for continuous operation.
- Temperature & Environmental Resistance: Temperature-resistant from -55°C to +70°C, moderately oil resistant, and suitable for tropical climates.
- Antistatic Properties: Antistatic in accordance with ISO 1813 for safe operation in sensitive environments.
- Dust-Proof Design: Dust-proof construction ensures reliability in outdoor and agricultural settings.
- Optimized V-Shape Geometry: Wedging action into the sheave groove multiplies the low tensioning force to increase friction on the pulley sidewalls, improving power transmission.
