We manufacture the cross-roller slewing bearings of the 11-series with raceway diameters up to 5,000 mm and roller diameters of 80 mm. They have a single-row roller raceway angled at 45° and are characterised by a permanent torque resistance at different loads and a higher dynamic lifetime compared with equivalent ball slewing bearings. Besides ball bearing slewing rings the crossed-roller place also higher requirements at the stiffness and accuracy of adjacent construction.
Size range from 500mm to 4000mm

Good supply
The definition of good supply should be punctual, continuous and steady. A good supply is the respect to our clients. Make our clients' each minute count. Your time is presious for us.
Good Appearance
Relentless pursue for good appearance is our ultimate concept about product. We are still on our way. A good appearance is a sign of product maturity. If the appearance of product is impeccable, there is no need to say its quality.
Good service
Service is a wide sense concept here. It not only refers to manners, attitude but the thinking in client's position as well. We are supposed to be conscious to put ourselves in client's place so as to solve the current and potential worries.
