RINGFEDER® Shrink Discs Introduction Keyless shaft-hub locking devices have been the cornerstone of the RINGFEDER®. For over 90 years, our product offering of internal clamping and external clamping locking devices and global support has been unparalleled in the industry. Clearances considered for the calculation of the function values dw Surface finishes For shaft diameter dw: Ra ≤ 3,2 μm For hub bore: Ra ≤ 3,2 μm Any other tolerances can be chosen. As long as the stated max. clearance is not exceeded, there will be no variations of the functional characteristics. Characteristics Shrink...

Two-part shrink discs by RINGFEDER® are characterised by an extremely flat single cone and transfer the necessary torque in a similar way to a taper interference fit. The screws on the shrink discs can be tightened without using a torque wrench and therefore the discs can be mounted quickly and easily. The transferred torque is thus ensured via route-controlled assembly. Three-part RINGFEDER® shrink discs are characterised by a steep double cone and transfer the required torque in a similar way to a taper interference fit. In contrast to this, however, the RINGFEDER® shrink discs can be...

Shrink Discs RINGFEDER® RfN 4051 Further information on RINGFEDER® RfN 4051 on www.ringfeder.com Lighter version for moderate transfer values – particularly suited for thin hubs and hollow shafts Light design – suitable for medium transmissible values when space is limited. The RfN 4051 is a three-part shrink disc and serves to transfer low to moderate torque. The narrow pressure rings require only a very small space. The transferrable torque can be set in a targeted manner for the corresponding application by changing the screw tightening torque. Slit inner ring – low forces and pressures...

Shrink Discs RINGFEDER® RfN 4161 Further information on RINGFEDER® RfN 4161 on www.ringfeder.com Forged outer/pressure ring for the best stress distribution and thus ideal material use. Route controlled version with defined displacement path. Very good concentricity characteristics through contact by both rings in the clamped condition. The assembly can be carried out without a torque wrench. The clamping is thus independent of the screws’ friction system. The RINGFEDER® RfN 4161 series is replaced by the larger RINGFEDER® RfN 4181 from an internal diameter of 220 mm. Standard series for...
