Features

Oldham Couplings

Easy to install with large angular/lateral misalignment allowances characteristics.

Spacers designed to flex and slide to allow misalignments.
Larger misalignment allowance ranges compared to the other types, making for easy to adjust for installing.
High rigidity type has bronze spacer material instead of resin, and has torque capacity 2x of the conventional type.
Space-Saving Type up to 17% shorter in length contributing to space saving machine designs.

Cautions

Use Precautions

Make sure to keep misalignment within the allowed range and avoid excessive torque. Otherwise the coupling’s life will be shortened considerably due to plastic deformation.
For your safety, enclose the revolving parts of equipment with a protective cover.
If the coupling item generates abnormal metallic noises, immediately turn off the equipment and identify the cause. Such noises may be an indication of improper alignment, shaft interference or a loose screw.
For applications with a large load fluctuation, apply an adhesive agent on the coupling’s screws to prevent them from loosening. Alternatively, select a coupling of a larger size/load capability.
