Shrink Discs
External shaft hub locking for high torque drive connections where friction fit, concentricity and repeatable mounting sequence are central to the design review.
- 14-480 mm shaft checks
- Nm torque table review
- ISO 286 fit discussion
Products
Ringfeder product families for shaft locking and coupling selection
Use this catalog hub to compare shrink discs, locking assemblies, rigid shaft couplings and flexible coupling lines by bore range, torque demand and installation access.
Locking Assemblies
Keyless shaft hub connections for pulleys, gears, sprockets and levers where backlash control and simplified shaft preparation reduce drawing complexity.
- Hub wall verification
- Surface pressure data
- Mounting screw sequence
Rigid Couplings
Compact couplings for accurately aligned shafts, test rigs and equipment modules requiring torsionally stiff power transfer and low maintenance inspection points.
- Concentric clamp design
- High torsional stiffness
- Low backlash fit
Tschan Flexible Couplings
Flexible coupling options help accommodate misalignment, shock loads and service access in pumps, conveyors, compressors and process machinery.
- Misalignment tolerance
- Element replacement paths
- Application duty notes
