Heavy-Duty Gear Couplings for Torque Transmission

Crowned and conventional gear-coupling families for torque transmission where the selected design permits relative shaft displacement. Compare torque, speed, bore, lubrication, tooth treatment and installation space before selecting a series.

Gear coupling FAQ

Questions About Gear Coupling Selection

Use these answers to compare gear-coupling structures and prepare the data needed for a preliminary review.

What is a gear coupling used for?

A gear coupling transmits torque between connected shafts while its tooth geometry accommodates the angular displacement permitted by the selected design. Confirm torque, speed, bore, shaft-end distance, lubrication and installation space for the actual duty.

How should a gear coupling be selected?

Start with nominal and peak torque, operating speed, bore and shaft arrangement. Then check displacement, shaft-end distance, environment, lubrication and the dimensional drawing for the specific model.

Do gear couplings require lubrication?

Many gear-coupling designs use specified lubrication, but the lubricant type, quantity and maintenance interval are model-dependent. Follow the applicable product documentation rather than assuming one lubricant for every series.

What information should I send for a gear coupling quotation?

Provide the driving and driven equipment, torque, speed, shaft diameters, bore and keyway details, shaft-end distance, installation envelope, operating environment and required quantity.

Need help with a model?

Send torque, speed, shaft and installation data for a preliminary review.
