Gear Heat TreatmentOur bearings are used both in heavy devices, such as armoured vehicles, and in sensitive optical devices. They are marked by their robustness, precision and reliability. Our bearing concepts are based not only on military norms and quality standards, but also on our decades-long experience and consequent research and development. Upon request, we are happy to carry out special measurements and tests in our R&D centre.

The single-row cross-roller slewing ring is also composed of two inner and outer rings, with compact structure, high manufacturing precision, light weight and small assembly clearance. The inner ring and the outer ring are connected by rollers, the rollers are arranged in a 1:1 cross, which can bear axial force, tilting moment and larger radial force at the same time. The structure of the cross roller bearing itself is a line contact, which can also be understood as a surface contact, and the line surface contact of the crossed round roller bearing is front, back and left, ensuring the stability of the entire layout.

It is widely used in lifting and transportation, military products, medical equipment, bucket wheel machines, park amusement machines, filling machines etc, which play a very important role in construction machinery products
