4071-320HT 320 RFN 4071HT SHRINK DISC KE
- Slit inner ring – low losses and pressure on the hub.
- Extension of the RINGFEDER® RfN 4061 series from an internal diameter of 220 mm up to the largest diameters. Cost-efficient solution with high capacity in the largest possible range of applications. The preload force can be set targeted to the relevant application.
- Unlimited range of applications – RINGFEDER® Shrink Disc connections are suitable for securing all types of hubs onto shafts and axles. Replacing traditional shrink fits, keys and polygon connections, splined shafts etc. So cog wheels and sprockets, levers, lifters, cam discs, pulleys or brake discs, balance wheels, couplings, slip on gear mechanisms, flanges, pulley wheels and rotors can be attached absolutely reliable.
- 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.
- Compensation of small tolerance errors – please contact our engineers.
- Maximum reliability – suitable for static, dynamic and impact loads.
- Slitted inner ring – low forces and pressures on hub and shaft.
- Simplified manufacture – only plain shaft and bore diameters with easily achieved surface finish and tolerances are required.
- Easy replacement – The RINGFEDER® shrink disc is free from any form fit.
- 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 removal – after loosening the locking screws, the RINGFEDER® Shrink Disc will self release and the hub will move freely on the shaft.
- 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.
