SPA1120 Wrapped Wedge V-Belt (SPA1120 Wedge Belt)
The SPA1120 Wrapped Wedge V-Belt is a high-capacity, heavy-duty narrow wedge power transmission belt engineered to maximize drive performance and energy efficiency across industrial machinery. Featuring a high depth-to-width ratio wrapped in a durable, wear-resistant fabric jacket, the SPA1120 delivers up to three times greater horsepower transmission capability than standard classical V-belts of equivalent width, allowing for more compact drive configurations and reduced pulley overhang loads.
Key Features & Performance Benefits
- High Power Wedge Profile: Deeper cross-section provides superior wedge action into sheave grooves, supporting substantially higher torque and speed ratios.
- Durable Fabric-Wrapped Jacket: High-density, rubberized textile wrap shields internal components against oil, heat, ozone, industrial dust, and abrasive wear.
- High-Tensile Cord Reinforcement: Prestretched polyester tension members ensure minimal elongation, excellent shock-load absorption, and dependable tension retention over long operating cycles.
- Smooth & Quiet Operation: Engineered for minimal vibration and quiet performance across high-speed industrial electric motor drives.
- Standardized Interchangeability: Manufactured in strict accordance with DIN 7753 Part 1 / ISO 4184 / BS 3790 / RMA IP-22 dimensional specifications.
