Periflex 11-3 / 19-3
Periflex Coupling Element
Rubber tyre element for Periflex-type highly flexible shaft couplings, in sizes 11-3 and 19-3. It transmits torque between the two hubs, compensates axial, radial and angular shaft misalignment and dampens torsional vibration and shock loads in the drive. Replacement element produced from our own tooling, available in series.

Typical applications
01
Pumps & compressors
Electric motor to pump or compressor drives where misalignment and start-up shocks must be absorbed.
02
Fans & blowers
Industrial ventilation and HVAC drives requiring torsional vibration damping and quiet running.
03
Conveyors & material handling
Belt and screw conveyor drives in quarries, cement plants, silos and agricultural facilities.
04
Maintenance & spare parts
Replacement tyres for existing Periflex-type couplings. The element is changed without moving the hubs.
