Overview

• Two part shrink heavy duty series – with additional guide mechanism for the inner ring. For the transmission of maximum torques.
• 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.
• Highest reliability – applicable for static, dynamic and impact loads.
• Simplified manufacture – only plain shaft and bore diameters with easily achieved surface finish and tolerances are required.
• Fully replaceable – The RINGFEDER® shrink discs work without any positive locking.
• Visual check of the tightening status – minimisation of faults during assembly.
• Easy mounting – RINGFEDER® Shrink Discs use standard screws and tightened using standard tools. No additional machining or fitting work is required.
• Short assembly times - cost savings particularly in series production.
• Low susceptibility to contamination – when the locking screws are tightened the contact (functional) surfaces are pressed firmly together and prevent the ingress of dirt and moisture.
• Easy adjustability – no stops, steps, key-ways, splines etc. are required therefore, hubs can be located and locked at any point or angle on the shaft.
