Zero Backlash Couplings
 |
R+W Economy Bellows Couplings - BKL
With a single ISO 4762 radial clamping screw per hub.
Self opening clamp system optional: Loosening the clamping
screw applies force to the pin, which will force the
clamp into the open position for easy mounting and dismounting.
Specs:
- Torque: capacities up to 4425 in-lbs.
- Bore diameters: 4 - 62 mm or 0.1875 - 2.375 in.
- High torsional rigidity
- Low moment of inertia
- Misalignment compensation
- Economical price

R+W Miniature Bellows Couplings - MK
The R+W miniature metal bellows couplings featured
in the MK series were developed for coupling applications
with potentiometers, tachogenerators, angle encoders,
and small, highly dynamic servo drives. These high quality
compact couplings guarantee high precision, backlash-free
angular motion transmission, particularly in closed
loop situations.
Specs:
- Torque: capacities up to 88 in-lbs.
- Bore diameters: 1 - 28 mm or 0.047 - 1.0 in.
- High torsional rigidity
- Multiple connection options
- High-speed capacity
- Misalignment compensation

R+W Elastomer Insert Couplings - EK
EK series provides zero backlash, several clamping
styles and four different insert types providing varying
degrees of torsional rigidity. These couplings are ideal
for maintaining position control while absorbing shocks
and vibration. They are an economical solution where
the extra cost of bellows or disc designs are not warranted.
Specs:
- Torque: capacities up to 14,100 in-lbs.
- Bore diameters: 3 - 80 mm or 0.125 - 3.125 in.
- 3 rigidity options
- Vibration dampening
- Electrically insulting
- Multiple connection options
