The MCNB-HS Series power-off spring applied brakes have oversized bores to allow wires to pass through the shaft’s hollow bore. They accommodate encoders, cables, hoses, shafts, and tools. The ratio of the brake’s field core diameter to outer diameter is leading the industry.
Internal designs allow for reduced backlash, high cycling, long life, optimized torque per size, thin profile, low weight, limited drag, low heat generation, and low power requirements. Reduced backlash is important for precision and accuracy. Special attention is made to supply stable performance and response during total life for high-cycle applications. Torque is optimized to provide a smaller package size and lower weight. The thin profiles give an advantage where space constraints are tight. Low power requirements reduce energy consumption and limit heat generation. MCNB-HS series is scalable and custom sizes can be available upon request.
