DOUBLE JOINT CARDAN COUPLING HD TYPE DJ-HDN-20X42 (3HD) KEYWAY

Universal joint couplings type DJ-HDN-20x42 (3HD) keyway (Cardan couplings) 

Universal joint couplings type DJ-HDN-20x42 (3HD) keyway (Cardan couplings) suitable for every application in the range of general engineering up to a maximum speed of 4000 rpm. Cardan couplings type HD precison double joint. Maximum articulation angle 90° for each joint. Bearings designed as plain bearings.

Our precision joints consist of a joint centre piece and two hubs that are interlinked by straps.
Bearing of the joint heads is made by plain bearings with precision joints type HD. The plain bearings type HD limit the maximum permissible speed to 4,000 rpm. The maximum diffraction angle of our cardan shafts per joint is 90°.

This bearing allows cardan shafts compared to other coupling types to compensate for significantly larger angular shaft displacements. Double joints that have two bearings are able to offset radial displacement in addition.

Precision joints in various Universal joint couplings DJ-HDN-20x42 (3HD) keyway

Precision joints consist of a joint centre piece and two hubs that are interlinked by straps.
Bearing of the joint heads is made by plain or needle bearing selected based on the kind of application.

This bearing allows the precision joints (single joints) to compensate for significantly larger angular displacements compared to other coupling types. Double joints that have two bearings are able to offset radial displacement in addition.

Precision joints / cardan shafts in an extendable version are able to offset axial displacement in addition to angular and radial displacement.

Precision joint HD: standard type as double cardan shaft / joint with plain bearings for speeds up to 4,000 rpm.
