Banded SPB Series Narrow Wedge Industrial V-Belts – Heavy-Duty Stability and High-Torque Power Transmission
Banded SPB Series Narrow Wedge Industrial V-Belts are engineered for demanding industrial applications that require superior torque capacity, exceptional stability, and long service life. Designed in accordance with DIN 7753 and ISO 4184 standards, these belts combine the high-efficiency performance of narrow wedge profiles with the enhanced alignment and vibration control of a banded construction. This makes them ideal for multi-groove drives operating under severe loads, high speeds, or continuous-duty conditions.
Engineered for Strength, Stability, and Efficiency
Each SPB rib features a 17 mm top width, 14 mm height, and a 40° included angle, providing greater power density than classical V-belts. The narrow wedge profile increases pulley contact and torque transmission while enabling more compact system designs. Multiple SPB belts are permanently joined with a reinforced rubber or fabric band, eliminating belt whip, preventing rollover, and ensuring synchronized performance across all ribs.
Built from oil-resistant, anti-static synthetic rubber and reinforced with high-strength polyester or aramid tensile cords, these belts offer outstanding resistance to stretch, heat, and environmental wear. Their construction supports reliable performance in temperatures ranging from -30°C to +80°C, making them suitable for rugged indoor and outdoor applications.
