PRODUCT

Oldham Coupling

Oldham Coupling - Set Screw Type



The OC Series has no shaft interference by penetrating the inside of the spacer. It is designed to relieve the pressure generated in the spacer, thereby reducing the frequency of coupling breakage. The OC Series spacer is a complete insulator, thus blocking electrical noise.

Ordering Instructions

  • Please specify the series, outer diameter, and bore size when placing your order.


  • If keyway machining (on the bore) is required, ensure to indicate this separately.


  • For assistance in selecting the right couplings, please contact our customer service center.

Standard Bore Diameter


※ Bore machining is available within the product’s minimum to maximum bore range beyond the standard bore sizes. (Refer to the figures on the right)
