Ruland OST16-5-A, 5/16" Oldham Coupling Hub, Aluminum, Set Screw Style, 1.000" OD, 0.467" Length
PRODUCT SPECIFICATIONS
Ruland OST16-5-A is an oldham coupling hub with 5/16" bore, 1.000" OD, and 0.467" length. 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. Disks are available in acetal plastic for zero-backlash and high torsional stiffness, nylon for shock absorption and dampening, and PEEK for high temperature and cleanroom environments. OST16-5-A can accommodate all forms of misalignment and are especially useful in applications with high parallel misalignment (up to 10% of the OD). It operates with low bearing loads protecting sensitive system components such as bearings and has 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. OST16-5-A is machined from bar stock that is sourced exclusively from North American mills and is RoHS2 and REACH compliant. It is manufactured in our Marlborough, MA factory under strict controls using proprietary processes.

| Product Notes | |||
Note 1 |
Stainless steel hubs are available upon request. |
Note 2 |
Performance ratings are for guidance only. The user must determine suitability for a particular application. |
Note 3 |
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. |
