This section will allow you to select hubs to be used individually or as part of an assembly. Ruland manufactures oldham couplings with a proprietary hub machining process that combined with the anodized finish improves lubricity and allows for the longest service life in the industry. Torque transmission is achieved by mating the slots on the center disk to the drive tenons on each hub. Oldham couplings can help protect expensive machine components by acting as a torque limiter during overload. The disc breaks cleanly and does not allow for any power transmission. Oldham couplings are also electrically isolating since disks are non-conductive
This section will allow you to select disks to be used individually or as part of an assembly. Ruland offers users the ability to tailor the performance of oldham couplings to match their application needs as disks are available in three materials, acetal for high torsional stiffness and zero-backlash, nylon for shock absorption and noise reduction, and PEEK for high temperature and low outgassing. The slots of the disk mate onto the tenons of the hub with a slight press fit to allow the coupling to operate with zero backlash. In the event of disk wear or failure, the disk can be easily replaced and the oldham coupling's original performance restored. Disks with a center hole are available upon request to allow full shaft penetration.
- Proprietary hub machining process leaves a smoother surface for interaction between hub and disk resulting in significantly longer life.
- Balanced design reduces vibration and allows for higher RPM.
- Accommodates a high amount of parallel misalignment (up to 10% of the outer diameter) with very light bearing loads.
- Three-piece design allows for ease of customization, installation, and blind assembly.
- Disks are available in nylon for dampening of impulse loads and noise reduction, acetal for high torque capacity and zero-backlash, and PEEK for high temperature and low outgassing.
- Stops transmission of power during overload conditions.
- Manufactured and stocked at our Marlborough, Massachusetts factory. Special designs are available.
- All Ruland oldham couplings are RoHS2 and REACH compliant.
