Description

GUMMI A-105 is a flexible coupling reference, within Power transmission. Request a quote for A-105 via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.

The GUMMI A-105 flexible coupling is a power transmission component that joins two shafts and absorbs misalignment and vibration through an elastic rubber center. It is used in equipment where continuous operation and protection against overloads are required. MR Accesorios Industriales carries this model with two standard hubs, a nominal torque of 3130 Nm and a maximum bore of 100 mm, for demanding industrial applications.

The GUMMI A-105 belongs to the Type A series and is configured with two standard hubs (CN). Its elastic rubber center has a diameter of 330 mm, while the total length of the assembly is 250 mm and the weight reaches 44 kg. The 40 mm pilot hole allows the bore to be machined up to a maximum of 100 mm according to the required shaft diameter. The nominal torque of 3130 Nm positions it for medium and high power transmissions.

This coupling is used in centrifugal pumps, industrial fans, screw compressors, conveyor belts and mills, among other equipment. Its rubber center design dampens torsional vibration and tolerates small angular, parallel and axial misalignments, which extends the service life of bearings and seals. It is a common solution in chemical, food and aggregate processing plants where reducing corrective maintenance is the goal.

To select the right coupling, verify the nominal torque of the drive and the diameter of the shafts to be joined. The maximum bore of 100 mm and the 40 mm pilot hole define the possible machining range. Take into account the permissible misalignment and the working environment: the rubber resists oils and moderate temperatures. Installation requires precisely aligning the hubs and checking the tightening of the fastening elements to avoid parasitic loads.

Frequently Asked Questions

What does the CN configuration mean on the GUMMI A-105 coupling?
CN indicates two standard hubs, meaning both ends of the coupling are standard hubs without special machining. This configuration is the most common for joining drive and driven shafts with an intermediate elastic rubber center.
Can I machine the bore of the GUMMI A-105 to a different size?
The coupling is supplied with a 40 mm pilot hole and accepts a maximum bore of 100 mm. Final machining must be done according to your shaft diameter, respecting the tolerances and balancing required for the operating speed.
How do I request an alternative if the A-105 does not fit my needs?
Write to us on WhatsApp with the current part number, your equipment torque and shaft diameters. At MR Accesorios Industriales we evaluate the Type A series or other flexible coupling options to give you a compatible solution promptly.
