The CBSF series couplings are robust, steel-body fluid couplings designed specifically for underground mining and heavy-duty industrial applications. These couplings offer shaft-to-shaft connection with a flexible coupling on one end and are optionally available with a Delay Fill Chamber (CBSF-DF) or Extended Delay Fill (CBSF-DX). Built to withstand harsh conditions, they deliver reliable torque control, reduced shock loads, and adjustable performance for complex start-up needs. These couplings are proven across mining, mineral processing, and other demanding operations.
