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.
