Sitong Industrial Cardan Shafts

In the past 20 years, Jiangsu Sitong Cardan Shaft has continuously improved hundreds of precision processes and 50 production inspection links with a rigorous attitude, and built each universal joint shaft with the spirit of artisans, aiming to provide customers with better products and services.

The flange fork head and the welding fork head are processed by the CNC machine to ensure the positioning tolerance between H7-H9 and ensure the tolerance of the parts within 0.1mm so that the whole shaft can run smoothly without jumping.

The positional relationship between the bolt holes on the flange plane of the flange fork and the keyway is very critical. The center distance and keyway of the hole processed by the CNC machining center are high, and the symmetry and verticality can reach less than 0.02 mm.

ZG35CrMo is used for our flange forks and welding forks. In order to eliminate the casting stress and improve the mechanical properties of the materials, we have tempered all flange heads and welding forks with a hardness of 238-268.

Quenching and tempering can improve the strength, ductility,and toughness of the material, thereby reducing the chance of damage to the Cardan shaft during use and extending the service life of the Cardan shaft.

Our custom balancer can balance the universal shaft with a length of 6 meters, a diameter of 1 meter and a weight of 3 tons. For the universal joint shaft with a speed higher than 300 rpm, the balance check is carried out before leaving the factory,Dynamic balance accuracy G16.
