Shrink discs, locking assemblies, rigid couplings

Ringfeder shaft locking assemblies indexed by DIN 6885 and ISO 286

For engineers matching shaft bore, transmissible torque and axial space, Ringfeder organizes shrink disc and coupling data into direct specification paths instead of broad catalog claims.

Specification groups for shaft locking review

Metric shaft references from 14 mm to 480 mm are reviewed against ISO 286 fit classes, surface pressure, hub wall thickness and bore preparation notes.

Selection notes compare transmissible torque, start stop frequency, reversing loads, shock factor and screw tightening sequence before a part number is released.

Datasheets, CAD references, tightening torque tables, mounting guidance and inspection intervals are packed for procurement and maintenance teams.

Minimal decision data

What engineers check before releasing a coupling drawing

01

Friction locking without keyway redesign

Ringfeder style shrink discs transmit torque through controlled surface pressure, helping teams update hubs without changing every shaft drawing.

02

Traceable tightening values

Assembly notes keep screw torque, lubrication condition and tightening sequence visible for shop floor repeatability.

03

Coupling family cross reference

Tschan flexible coupling and rigid coupling options are positioned by misalignment, shaft diameter and maintenance access.

04

Procurement friendly packets

Datasheet, CAD and compliance links are grouped so buyers can issue RFQs without chasing separate documents.
