OPTIBELT Vee Belt Pulley Cast Iron 280 mm Pitch, 4 Tooth TB SPA 280/4

OPTIBELT TB SPA 280/4 Vee Belt Pulley is a high-quality mechanical power transmission component made from robust cast iron. It features a 280 mm pitch diameter and 4 teeth grooves suitable for the SPA 13 TB SPA 280/400ZA profile. The pulley is precisely balanced in one plane to minimize vibration, which is achieved by balancing without the key on a smooth mandrel. This ensures smooth operation when used with taper bushings in power transmission systems.

The pulley bore diameter is 55 mm, allowing proper shaft fitting with taper bushings. It is designed for industrial applications including manufacturing processes, machine assembly, and mechanical power transmission where durable and reliable belt engagement is required.

The cast iron construction provides resistance to wear and deformation, enhancing the pulley’s lifespan even under demanding operating conditions. This pulley is compatible with machines requiring balanced rotors and is ideal for installations that require a finished bore without key and no inserted spring for balanced rotor setups.

Typical use cases include industrial machinery, manufacturing plants, HVAC systems, and other equipment relying on belt-driven power transmission solutions. Its specific design facilitates efficient torque transfer and long-term operational reliability.

The pulley features a 280 mm datum diameter for compatibility with SPA profile V-belts. Constructed from durable cast iron material ensuring long service life. Equipped with 4 teeth grooves for optimal belt engagement and torque transfer.

Bore diameter of 55 mm enables secure shaft mounting with taper bushings. Balanced in one plane to reduce vibration and enhance machine stability. Designed for use in industrial, manufacturing, and mechanical power transmission systems.
