A70 Classical V Belt

A70 Classical Wrapped V-Belt (A70 Classical V Belt)

The A70 Classical V-Belt is a premium, heavy-duty industrial power transmission belt engineered for reliable, continuous performance across high-torque machinery and industrial drive systems. Constructed with a heavy-duty fabric jacket enclosing high-tensile polyester tension cords and an oil-and-heat-resistant rubber core, the A70 ensures uniform power transfer, minimal stretch, and superior resistance to harsh environmental factors.

Key Features & Performance Benefits

• Durable Wrapped Construction: High-density, bias-cut rubberized fabric wrap protects the belt core from oil, dust, heat, ozone, and abrasion while providing smooth clutching and slip resistance.
• High-Tensile Tension Members: Helically wound, prestretched polyester cords deliver maximum tensile strength, shock-load absorption, and low-stretch characteristics.
• Optimized Wedge Friction: High-friction side contact with pulley grooves ensures maximum grip and high mechanical efficiency across varied operating speeds.
• Standardized Interchangeability: Conforms strictly to DIN 2215 / ISO 4184 / BS 3790 / RMA IP-20 international engineering and dimensional standards.
