RINGFEDER - RFN 4051-380x585

Details

(THREAD = M20), The RINGFEDER 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. Lighter version for moderate transfer values – particularly suited for thin hubs and hollow shafts. Shrink discs are the modern method for creating a mechanical shrink fit. The shrink disc consists of either one or two thrust rings with tapered bores and a mating tapered inner ring. By tightening locking screws the thrust rings are drawn together compressing the inner ring and applying pressure to the outside of the hub clamping it to the shaft. Features are : Light design, Compensation of small tolerance errors, Maximum reliability, Slitted inner ring, Easy mounting, Low susceptibility to contamination.
