SPB Series Narrow Wedge Industrial V-Belts – High-Torque, Space-Efficient Power Transmission for Heavy Industrial Applications
SPB Series Narrow Wedge Industrial V-Belts are engineered to deliver exceptional power transmission performance in heavy-duty applications where high torque, reliability, and compact design are essential. As part of the metric narrow wedge belt family, SPB belts comply with DIN 7753 and ISO 4184 standards, making them fully compatible with European and international industrial machinery. Their optimized wedge geometry provides superior power density compared to classical V-belt designs.
High-Strength Construction for Demanding Drive Systems
With a 17 mm top width, 14 mm height, and a 40° included angle, SPB belts deliver robust torque transfer while supporting high-speed operation and compact pulley layouts. Manufactured from high-quality synthetic rubber and reinforced with durable polyester tensile cords, these belts offer excellent resistance to heat, oil, and wear. The SPB profile is available in both smooth and cogged versions, with cogged options providing improved flexibility and reduced heat buildup for enhanced performance on smaller pulleys.
The deeper wedge design ensures reliable pulley engagement, reduced slippage, and stable performance under continuous load—ideal for demanding industrial environments.
