The GUMMI A-140/140 flexible coupling is a power transmission component that joins two shafts and absorbs misalignment, vibration and torque peaks. Its elastic rubber center works in compression and allows smooth operation in equipment with variable loads. It is used in pumps, fans, conveyor belts and industrial machines where the transmission needs protection. MR Accesorios Industriales carries this brand with more than 80 years of experience in the field.

This coupling corresponds to the GUMMI Type A series, with a two standard hub (CN) configuration. The A-140/140 model accepts a nominal torque of 8500 Nm, a maximum bore of 140 mm and a pilot hole of 45 mm. The elastic center has a diameter of 403 mm, the total length is 380 mm and the weight reaches 94 kg. These dimensions allow it to be selected for large shafts in demanding transmissions.

Typical applications include centrifugal pumps, industrial fans, mills, mixers and conveyors. In all cases, the coupling compensates angular and radial misalignment, reduces vibration transmission and dampens overloads. It is a common solution in chemical, food and process plants, where operational continuity and simple maintenance are a priority.

For installation, verify that the shafts are aligned within the tolerances recommended by the manufacturer and that the hub bore matches the shaft diameter. The 45 mm pilot hole allows the final bore to be machined up to 140 mm as needed. Select the coupling based on nominal torque, speed and type of load. The elastic rubber center should be inspected periodically to detect wear or hardening.
