Crossed-roller slewing bearings
All slewing bearings in the X1 series are crossed-roller bearings. They are primarily used for service conditions requiring a uniform rotational resistance despite changing loads as well as high requirements of precision and stiffness.
A lot of these bearings, especially those in our standard range, are preloaded and manufactured with centerings on both the inner and the outer ring.
Crossed-roller bearings are used in various applications in machine tool engineering, robotics, tunneling machinery and positioning systems.
Depending on the type of gear, most bearings in this series fall into one of the following groups:
