The cardan coupling Crossflex
Axially rigid coupling combines the properties of a universal joint with those of an Oldham coupling
The Crossflex cardan coupling has the ability to withstand axial forces. This makes it ideal for applications with additional light tensile and compressive forces. Kinematically, the Crossflex combines the properties of an Oldham coupling with those of a universal joint. It consists of two aluminium hubs and a central stainless steel inner ring. In this inner ring there are steel pins arranged at an angle of 90° to each other.
Product features
- High angular displacement up to 5°
- Nominal torque range from 0.25 to 5 Nm
- Bore diameters from 4 to 15 mm
- Low restoring forces
- Compact, space-saving design
Angular misalignment up to 5°, corrosion-protected aluminium hubs
This centre section, which resembles a spider, can perform a simultaneous swivel and linear movement in the plain bearings when radial and angular misalignments occur. This enables the lightweight articulated coupling to compensate for angular misalignments of up to 5° and radial misalignments of up to 0.5 mm. The steel pins are also nickel-plated to optimise the friction coefficients and sliding properties. The pairing of the nickel-plated pins and the plain bearings is selected and adapted in such a way that restoring forces and backlash are minimised. The aluminium clamping hubs are additionally anodised for increased corrosion protection.
Different versions
In addition to the standard GCC series (clamping hub design), the Crossflex programme also offers compact versions for tight installation spaces in the form of the ZCC design.
