Overview CB clutch is an ideal match for clutch as well as brake applications in operations that are high speed and cyclical. They are also suitable for coupling and general transmission of power.The sidewalls of an adaptable neoprene and cord actuating tube are used for delivering torsional resilience through power transmission. This enables the units to

Core components include service calipers (BK-00-7B/BK-00-6D) and emergency calipers (BK-0-7B/BK-0-6D), paired with robust hydraulic control units for responsive operation. Designed to withstand harsh drilling environments, these brakes feature durable friction discs, corrosion-resistant steel
