Oldham couplings for conveyor systems
Oldham couplings from Ruland are zero-backlash, have a balanced design, accommodate large parallel misalignment, and are highly versatile, making them an ideal fit for precise positioning and general industrial conveyor systems. They also facilitate easy disassembly of rollers to allow for cleaning, replacement and general maintenance.
Ruland oldham couplings are comprised of two anodised aluminium hubs and a torque transmitting center disk. This allows a single coupling to combine clamp and set screw hubs with inch, metric, keyed and keyless bores. Ruland uses a proprietary hub machining process that leaves a smoother surface for interaction between the hub and disk, resulting in long life and reduced downtime. Oldham couplings from Ruland have a balanced design for reduced vibration at high speeds. Modular conveyor systems benefit from a standard coupling that can be installed on different motor, shaft and roller configurations.
Oldham couplings accommodate all forms of misalignment, and are best suited for parallel misalignment. They operate with low bearing loads protecting system components such as bearings. The disk is available in acetal for high torsional stiffness, PEEK for high temperature and low outgassing, and nylon for shock absorption and noise reduction.
