FOR SHAFT MISALIGNMENT COMPENSATION |
 BEAM COUPLINGS Zero backlash Angular & parallel misalignment One piece construction High flexibility No wearing parts Constant velocity No lubrication required |
 JAW COUPLINGS Angular, parallel & axial misalignment Good shock resistance Constant velocity Easy disassembly No lubrication required High torsional stiffness |
 OLDHAM COUPLINGS Good shock resistance Constant velocity Easy disassembly No lubrication required High torsional stiffness Low backlash |
 SILICON COUPLINGS Designed for anti-vibration Good shock resistance |
| When installing stepper or servo motors, gearboxes and encoders in machines, care must be taken to ensure all devices are co-axial, i.e. no angular or parallel misalignment. Failure to do so may place excessive loads on bearings and reduce life of the components. Using flexible couplings with some angular and parallel compliance will ensure this while maintaining constant velocity and low or zero backlash. | Ideal
for: stepper motors & servomotors, shaft encoders, ballscrews, gearboxes, tachogenerators, potentiometers, transducers, linear drives, friction clutches, resolvers |

The coupling consists of several helical slots cut into a solid cylindrical section forming beams. Because the couplings are machined from a single section, they have constant velocity and do not contribute to backlash in position control systems. Both 6 beam and 3 beam couplings are available. Six beam couplings have greater flexibility and 3 beam couplings are better where space is limited. The multibeam couplings are available in aluminium alloy, carbon steel and stainless steel. Both setscrew and clamp shaft fixings are available. The clamp style is more expensive but have better shaft locking ability in high torque applications. Couplings can be supplied with custom bores or small diameter pilot bores at each end enabling easy boring in a lathe. |
