Martin Blue-Flex Grid Couplings handle high torque levels and high RPM applications in a small package.
Unlike other metallic couplings, Martin Blue-Flex Grid Couplings have the ability to reduce vibration and cushion shockloads to driven and driving power transmitting equipment components.
Martin Blue-Flex Couplings are available in sizes 1020-1170 in vertical and horizontal configurations with a rough stock bore.
Same day/next day rebores are available upon request.
