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.

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.
