Timken B143R Super II V-Belt, B Section, Nominal Length, Raw Edge EPDM B143R 143 in.

The Timken Super II B143R V-Belt is a B-section classical raw edge power transmission belt, engineered with EPDM for optimal performance. Its raw edge construction and central cord placement ensure flexibility, stability, and high efficiency, averaging 95% according to the U.S. Department of Energy. EPDM provides durability, resistance to oil, heat, hardening, and glazing, along with static conductivity, operating effectively from -50°F to +250°F. Designed to reduce belt whip and rollover in multi-belt drives, this belt extends service life and reduces maintenance. It is built to meet or exceed ARPM tolerances for a matched set.
