Banded SPC Series Narrow Wedge Industrial V-Belts – Maximum Power Transmission for Extreme Industrial Demands
Banded SPC Series Narrow Wedge Industrial V-Belts are engineered for maximum efficiency, durability, and stability in high-torque, heavy-duty power transmission systems. Designed to meet DIN 7753 and ISO 4184 standards, these belts combine the superior load-handling capability of the SPC wedge profile with the enhanced reliability of a banded construction. This makes them ideal for multi-groove industrial machinery where vibration control, synchronized belt tracking, and long service life are essential.
Engineered for Superior Strength and Stability
Each SPC rib features a 22 mm top width, 18 mm height, and a 40° included angle, delivering exceptional torque transmission and higher power density compared to classical V-belts. The narrow wedge geometry improves traction and reduces slippage, enabling more compact yet more powerful drive systems.
The banded design permanently joins multiple SPC belts into a unified structure with a flexible, reinforced band that prevents belt whip, eliminates side-tracking, and ensures even load distribution across all ribs. Built from oil-resistant, anti-static synthetic rubber and reinforced with high-tensile polyester or aramid cords, these belts deliver outstanding durability, heat resistance, and dimensional stability.
Available in cogged or raw-edge configurations, Banded SPC belts offer enhanced flexibility, smoother operation, and increased efficiency—especially valuable in high-speed or shock-loaded environments.
