SPZ Series Narrow Wedge Industrial V-Belts – Efficient, Space-Saving Power Transmission
SPZ Series Narrow Wedge Industrial V-Belts are specifically engineered to provide reliable, high-efficiency power transmission in compact industrial drive systems. Manufactured in compliance with DIN 7753 and ISO 4184 standards, these belts are part of the narrow wedge family designed to deliver greater torque and power density than traditional classical V-belts. Their reduced width and optimized geometry make SPZ belts ideal for applications where space is limited but performance cannot be compromised.
High-Efficiency Design for Compact Drives
SPZ belts feature a streamlined profile that enhances pulley engagement and reduces slip, resulting in improved energy efficiency and smoother power transfer. Built from oil- and heat-resistant rubber compounds and reinforced with durable polyester tension cords, SPZ belts offer excellent stability, minimal stretch, and consistent performance in demanding environments. Their design supports high-speed operation, short center distances, and multi-belt configurations, making them exceptionally versatile.
