UNIVERSAL JOINT COUPLING KTR TYPE GA-HA (CARDAN COUPLINGS)

Universal joint couplings type GA & HA (Cardan couplings)

Universal joint couplings type GA & HA (Cardan couplings) precision double joint - extendable, maximum articulation angle 45° for each joint. Bridging of bigger shaft distances. Cardan couplings type GA (plain bearing) nmax. = 1000 rpm & Type HA(needle bearing) nmax. = 4000 rpm.

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 shaft / precision joint acc. to DIN 808

Cardan shafts / precision joints GA & HA KTR in an extendable version are able to offset axial displacement in addition to angular and radial displacement.
Precision joints in various versions acc. to DIN 808
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 GA & HA in an extendable version are able to offset axial displacement in addition to angular and radial displacement.
