The OPTIBELT TB SPA 71/3 Pulley is a premium V-belt pulley engineered for optimal power transmission and longevity in industrial applications. Crafted from high-grade grey cast iron, this 71mm diameter pulley features three precision-machined grooves (SPA profile) to ensure smooth and efficient operation with compatible 12.7mm wide V-belts. Its design adheres to strict ISO 4183 (DIN 2211) standards, guaranteeing reliability and consistent performance.

One of the standout features of the OPTIBELT TB SPA 71/3 is its compatibility with TB 1108 taper bushings. This innovative mounting system allows for quick, secure, and precise installation onto shafts, eliminating the need for specialized tools. The taper bushing provides both keyed fastening and axial locking, preventing displacement and ensuring a stable connection even under heavy loads.

Weighing approximately 0.800 kg without the bushing, this pulley is statically balanced to minimize vibrations, which not only enhances operational quietness but also significantly extends the service life of both the pulley and the V-belt. This makes it a cost-effective solution for long-term use.

Commonly found in a wide range of machinery, including compressors, blowers, and equipment in the paper and chemical industries, the OPTIBELT TB SPA 71/3 Pulley is a testament to Optibelt’s commitment to quality and performance. Its robust construction makes it suitable for demanding environments, providing dependable power transfer in critical drive systems. Invest in this pulley to ensure the smooth, efficient, and reliable operation of your industrial machinery.
