The GUMMI A-70 flexible coupling connects two shafts while absorbing misalignment, vibration and load peaks. Its rubber flexible center supports smooth, quiet operation and helps protect the driven equipment. This makes it a practical choice for industrial drives where reliability and low maintenance matter. MR Industrial Accessories LLC supplies it as part of its power transmission line.

The A-70 belongs to the Type A series and comes configured with two standard hubs (CN). Key ratings include a nominal torque of 1170 Nm, a maximum bore of 65 mm and a pilot bore of 25 mm. The flexible center measures 224 mm in diameter, the coupling is 185 mm long overall, and it weighs 13.3 kg. Together these figures suit it to demanding power transmission duty.

Typical installations include centrifugal pumps, compressors, fans, conveyor belts and mills, along with other rotating equipment. The rubber center damps torsional vibration and compensates angular and radial misalignment, which helps reduce wear on bearings and seals. It is used in food, chemical, petrochemical and general process plants where uptime is important.

When selecting an A-70, check the torque the application requires, the rotation speed and the shaft diameters to be joined. The 65 mm maximum bore and 25 mm pilot bore allow the hubs to be machined to final size. Verifying alignment at assembly is essential to get the most from the flexible element and to avoid parasitic loads that could harm the equipment.

If you need a different configuration or size within the Type A series, ask about the alternatives. We supply GUMMI couplings and can help you choose the option that fits your system.
