Cardan Joints

The cardan cross is the central element of the cardan joint, allowing the transfer of torque and rotational movement between shafts at various angles. It consists of a cross body and four precision needle bearings, which are mounted on the arms of the cross and protected by high-quality seals. This construction ensures minimal friction and a high degree of rigidity in the transmission, which is crucial for stable operation of drive assemblies at high speeds and varying loads.

To ensure a long service life, cardan crosses are made of forged alloy steel with heat-treated running surfaces that are resistant to material fatigue. Most designs include integrated lubrication fittings that allow for regular maintenance and the expulsion of contaminants from the bearing space. Proper selection of the dimensions and performance of the cardan cross is essential to prevent vibrations, reduce noise, and protect the entire transmission system from excessive shock loads.
