Ruland OD21/33-PEK, Oldham Coupling Disk, PEEK, 1.313" (33.3mm) OD
PRODUCT SPECIFICATIONS
Ruland OD21/33-PEK is an oldham coupling disk designed to fit hubs with an OD of 1.313" (33.3mm). It is a component of a three-piece design consisiting of two anodized aluminum hubs press fit onto a center disk. This three-piece design allows for a highly customizable coupling that easily combines clamp or set screw hubs with inch, metric, keyed, and keyless bores. OD21/33-PEK is made from PEEK for high temperature and cleanroom environments. Oldham couplings can accommodate all forms of misalignment and are especially usefule in applications with high parallel misalignment (up to 10% of the coupling OD). They operate with low bearing loads protecting sensitive system components such as bearings and have a balanced design for reduced vibration at speeds up to 6,000 RPM. Hardware is metric and tests beyond DIN 912 12.9 standards for maximum torque capabilities.

| Product Notes | |||
Note 1 |
Performance ratings are for guidance only. The user must determine suitability for a particular application. |
Note 2 |
Torque ratings for the couplings are based on the physical limitations/failure point of the torque disks. Under normal/typical conditions the hubs are capable of holding up to the rated torque of the disks. In some cases, especially when the smallest standard bores are used or where shafts are undersized, slippage on the shaft is possible below the rated torque of the disks. Keyways are available to provide additional torque capacity in the shaft/hub connection when required. Please consult technical support for more assistance. |
