Locking Assemblies RfN 7013.0 | RINGFEDER®

These Locking Assemblies are of single-taper design with a self-locking taper providing good self-centering action and concentricity, as well as increased torque capacity. A pre-centering hub section is not required. Integral push-off screws for disassembly are provided. This unit can be placed deep inside a bore due to it’s design. Available sizes: Metric series shafts from 20 mm to 150 mm dia. and Inch series for shafts from 1” to 4” diameter.

This series is also available in true inch sizes.

Product Characteristics

  • Excellent concentricity and very easy to dismantle – these Locking Assemblies provide particularly good concentricity between the clamped parts. The flange is reinforced at the critical point. This prevents a bending and lifting of the inner ring during installation and therefore a good dismantling is ensured.
  • High rotation speed – the Locking Assemblies remain true-to-form during assembly and so they are suitable in applications with higher rotational speeds.
  • High radial loads – the material strength of the RfN 7013 Locking Assemblies makes them especially suitable for applications with high radial loads.

 

Example applications

  • crane running wheels
  • couplings
  • gearwheels
  • flywheels
  • fan wheels

Mounting of Locking Assembly

The Locking Assemblies are supplied slightly oiled and ready-to-use. The values for T, Fax, pW and pN apply to Locking Assemblies in delivery condition.

Surface finishes

For shafts and hub bores Ra = 1,6 μm

Tolerances

We recommend the following mounting tolerances

Shaft: h8; Hub: H8


Change of screw tightening torques

A change of the TA-values given in the above table is not admissible.
