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
  


---------------------------------------------BEAM COUPLINGS---------------------------------------------

Upto 38mm dia and 22Nm torque

Upto 19mm bore size

6 beam & 3 beam

Aluminium alloy, carbon steel and stainless steel 

Setscrew or clamp fixing

 

6 Beam aluminium couplings usually stocked. Contact Office for larger sizes.

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. 

 

----------------------------------------------JAW COUPLINGS----------------------------------------------

Upto 30mm dia and 25Nm torque

Upto 14mm bore size

Good shock resistance

Easy disassembly 

Setscrew fixing

 
This coupling consists of two aluminium hubs with jaws and a hard polyurethane polymer insert that fits between the jaws. This allows both angular and parallel misalignment and if the insert fails it can be replaced.

Couplings can be supplied with custom bores or small diameter pilot bores at each end enabling easy boring in a lathe.

-------------------------------------------OLDHAM COUPLINGS-------------------------------------------

Upto 30mm dia and 25Nm torque

Upto 14mm bore size

Good shock resistance

Easy dissasembly 

Setscrew fixing

 
This coupling consists of two aluminium hubs with jaws and a polyacetyl polymer insert that fits between the jaws. This allows both angular and parallel misalignment and if the insert fails it can be replaced.

Couplings can be supplied with custom bores or small diameter pilot bores at each end enabling easy boring in a lathe.

--------------------------------------------SILICON COUPLINGS--------------------------------------------

Upto 32mm dia and 8Nm torque

Upto 19mm bore size

Good shock resistance

Designed for low vibtration transmission

Setscrew and clamp fixing


This coupling consists of two aluminium hubs with jaws and a silicon polymer that is cast between the jaws. This allows both angular and parallel misalignment. These are designed to reduce the transmission of vibration.
