Accessories for rotary encoders - Couplings, Wheels, Armss-1

Shaft COUPLINGS for encoders Series BSS – WA – SK - FK A flexible coupling mounted on the encoder shaft ensures a smooth connection to the drive system: compensating for possible misalignmens and dampening vibrations, it protects the bearings from damaging overloads and extends their life. A variety of couplings with different sizes and stiffness is available to suit to any application. SPECIFICATIONS Materials Max. torque Max. offset off shafts radial/axial angular Torsion spring stiffness Nm/rad Radial spring stiffness

Shaft COUPLINGS for encoders Series PF The peculiar design of double loop couplings, with their special plastic equalising element, makes them extremely shock- and vibration-damping, rigid on the one hand, but less torsionally stiff on the other. Doubleloop couplings can therefore compensate for very large radial, axial and angular misalignments. Thanks to their plastic loops they also offer excellent electrical decoupling and thermal insulation. They are available in two sizes, with different boring.
