2. Characteristics of KTR Cardan Couplings GA-HA
– Manufacturer brand: KTR/Germany.
– Cardan shaft / precision joint acc. to DIN 808.
– Type GA: Extendable precision double joint with plain bearing.
– max. speed type GA = 1,000 rpm
– Type HA: Extendable precision double joint with needle bearing
– max. speed type HA = 4,000 rpm
– Maximum angular misalignment: 45°
– Maximum bore diameter: 50 mm
– Designed with a single center joint and two centers allowing GA-HA to be linked together with a belt. This expanded version enables axial and radial offsets to be compensated for.
– The precision joint GA-HA allows bearings to compensate for significantly larger angular displacements compared to other types of couplings. Additionally, double joints with two shaft journals can compensate for radial displacements. Bearings for the coupling ends are manufactured with either plain or needle bearings selected based on the application.
