Bearing of the joint heads is made by plain bearing with precision joint type GA and by needle bearing with precision joint type HA.The plain bearings of precision joint type GA limit the maximum permissible speed to 1,000 rpm, the needle bearings of precision joint type HA limit the maximum permissible speed to 4,000 rpm. The maximum diffraction angle per joint is 45°.
Cardan shafts / precision joints in an extendable version are able to offset axial displacement in addition to angular and radial displacement.
