OPTIBELT Vee Belt Pulley, Cast Iron 4 Tooth

The Optibelt TB SPC-375-4 V-belt pulley is a heavy-duty, cast-iron pulley designed for high-power and industrial drive systems. Featuring a 375 mm datum diameter and four grooves, this pulley is engineered for taper-lock bush mounting (e.g., TB 35/35 series) and meets ISO 4183 (DIN 2211) dynamic balance tolerances up to high peripheral speeds. Its durable cast iron construction and precision-machined design make it suitable for compressors, blowers, machine tools, and other demanding applications where a reliable belt-drive transmission and minimal vibration are critical.

Benefits of Using the OPTIBELT TB SPC-375-4 Vee Belt Pulley

By selecting the TB SPC-375-4 V-belt pulley, you gain a robust power-transmission component capable of handling high-load, high-speed environments. It reduces downtime due to pulley failure or misalignment. Its standardised taper-lock mounting simplifies maintenance and spare-part workflows, while its cast-iron build ensures durability, improved belt life and consistent drive efficiency.
