Shrink Disc RfN 4061-36 - Standard Series/split

RfN 4061-36 Shrink disc is the modern method for creating a mechanical shrink fit. RINGFEDER® Shrink Disc connections are suitable for securing all types of hubs onto shafts and axles.

• Standard series – this is the most popular shrink disc. High transmission values are possible and by varying the screw tightening torque the shrink disc can be adapted to the design specification.

• Maximum reliability – suitable for static, dynamic and impact loads.

• Easy mounting – no steps, keyways, splines are required, therefore hubs can be located and locked at any point or angle on the shaft. RINGFEDER® Shrink Discs use standard screws tightened with standard tools. No additional machining or fitting work is required.

• Easy replacement – the RINGFEDER® Shrink Disc is free from any form fit.

• Easy removal – after loosening the locking screws, the RINGFEDER® Shrink Disc will self release and the hub will move freely on the shaft.

• Simplified manufacture – only plain shaft and bore diameters with easily achieved surface finish and tolerances are required.

• Low susceptibility to contamination – when the locking screws are tightened the functional contact surfaces are pressed firmly together and prevent the ingress of dirt and moisture.
