RFLex COUPLINGS

RFLex Couplings are made with Disc Set and Steel Hubs for clamping. These Discs are bolted alternately to the Steel Hubs from both sides of Disc Sets. RFLex Coupling is made with the three- or five-pieces’ assembly of 2 no. Steel hubs or 2 no. Steel hubs and 1 No. Steel Spacer and 1 no. or 2 no. of Stainless-Steel Disc sets. These three or five parts are assembled with bolts with precision. This assembly becomes a Backlash Free and High Torsional Stiff, precise, long life RFLex Coupling. RFLex Coupling Couplings are more suitable for higher RPM, Temperature, uni-direction, or bi-directions.

Lamina details: Laminae sets come with the following details.

From 20 to 50, Square Shape and 4 Holes as standard. 6 Hole designs available on request.
From 60 to 135 Hexagonal and 6 Holes.
