Frequently Asked Questions

What is a MARTIN Chain Shaft Coupling Hub used for?

A MARTIN Chain Shaft Coupling Hub connects two rotating shafts in industrial power transmission systems, such as conveyors and pumps. It uses a roller chain to transmit torque while accommodating minor misalignment. This steel hub with a 2-7/16 in bore is designed for heavy-duty applications requiring reliable, low-maintenance coupling.

What are the specifications of the MARTIN 6018 x 1-7/8 coupling hub?

The MARTIN Chain Shaft Coupling Hub model 6018 x 1-7/8 has a steel construction, a round keyed bore diameter of 2-7/16 in, and a keyway size of 1/2 in x 1/4 in. It is size 60 and manufactured by MARTIN. This hub is designed for use with roller chain couplings in industrial drivetrains.

Where to buy MARTIN chain coupling hubs worldwide?

You can source MARTIN chain coupling hubs, including the 6018 x 1-7/8, through 3G Electric. As a global industrial equipment distributor since 1990, 3G Electric handles full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time.

How to select the correct MARTIN chain coupling hub?

To select the correct MARTIN chain coupling hub, match the bore diameter and keyway size to your shaft dimensions. For the 6018 x 1-7/8, the bore is 2-7/16 in with a 1/2 in x 1/4 in keyway. Also verify the hub size (60) and material (steel) suit your torque and environmental requirements. Consult MARTIN's catalog for chain pitch compatibility.
