The SIT-LOCK® keyless locking devices produced by SIT S.p.A. for more than 30 years are ideal for any shaft-hub connection application.
Suitable for taper bores 1108, 1210, 1610, 2012, 2517 and 3020. With bore diameters from 12 to 70 mm.
SER-SIT® taper bushing is designed to give the following features.
Standard 3-piece version for high torques. Universal applications.
Extremely slim versions for universal applications.
Identical to the RfN 7012, but optimised for extreme loads.
Transmits high combined forces and moments. Very good centring capability.
Ideal for maximum torques, axial forces and radial forces; self-centring.
Slit version
Standard solid version
The RfN 7004 locking assembly is an extended version of the tried-and-tested RfN 7003 series.
Long 3-piece version for high torques, self-centring.
Ideal stress distribution and maximum corrosion resistance
Narrow locking assembly made of stainless steel.
Ultra-narrow 4-piece version. Due to the clamping cones, there is no axial displacement. Self-releasing.
Locking assembly with excellent radial run-out and a stainless steel flange, self-centring.
Identical to the RfN 7012, but suitable for high bending moments thanks to the optimised screws.
Short 3-piece version with flange, self-centring. Due to the flange, there is no axial displacement.
5-piece precision locking assembly, self-centring. No axial displacement of the hub and shaft.
RINGFEDER RfN 8006 locking elements can be used to establish compact, screwless, and wear-free shaft-hub connections
5-piece precision locking assembly, self-centring. No axial displacement of the hub and shaft.
Extended 3-piece version, self-centring. Suitable for bending moments and radial loads.
