Through bore slip ring

Product Type:Through Bore Slip Ring Product Model:PSR-T70
PSR-T70 is a commercial slip rings that with a 70mm through-bore and a 138mm outside diameter.Use fiber brush technology which offers several advantages over conventional slip ring contacts including multiple points of contact per brush bundle, low contact force per fiber and low contact wear rates. In addition fiber bush do not require lubrication and produce virtually no wear debris....

  Installation Guide:

1.Main shaft mouted units:
A.Position the slip ring in the desired location and tighten both set screws to the shaft.Maximum torque 25Ib-in(DO NOT OVER TORQUE)
B.Route the wiring and make the neccessary connections.Do not allow the wiring to restrict free rotation of the slip ring.Do not constrain wiring such that wire flexing occurs.Doing so will ultimately cause failure(breakage of the wiring)

2.Housing mouted units:
A.Anti-Rotation tap used for connecting the stator of slip ring with the stationary member of euipment
B.Route the wiring and make the neccessary connections.Do not allow the wiring to restrict free rotation of the slip ring.


Because of possible geometric mismatching between the customer's application and the slip ring,'hard mouting'of both ends of the slip ring(i.e.securing the rotor and stator such that there is no floating during operation) is not recommended and may cause premature failure.
