Forest Machinery requires strong components, the most famous worldwide manufacturers choose our slewing bearing for our optimised design and the capacity of our slewing rings to work in a tough environment. Our finishing by grinding brings a valid pre-loading which is very important for the life time of the bearing and the comfort of the forest machine’s drivers. Our slewing rings accept the shocks and the high rotating speed of the de-barkers as well as the temperature of the coldest forests....
Because of the light structure of the crane, the lwjw bearing is an essential and strategic part. Our design matches perfectly the life time required by the customer. The quality and the precision of our manufacturing is the key to ensure good running after many cranes dismantling. In this application the lyjw slewing bearing helps construct buildings everyday all around the world with total security....

The assembly is much more compact and its hollow centre permits the installation of driving mechanisms and the passage of various control devices; the superstructures of the rotating part are more easily accessible. The small difference in height between the geared ring and un-geared ring reduces the overhang of the driving pinion....
Over decade years we have optimized every data of the Slewing Ring to match customer requirement lifetime & reliability being a major issue of those applications. Specific finish process of the raceways along with high accuracy of the preloads has established lyjw as a Expert on this application....
Robots are used in various industries to position work pieces very quickly and accurately. Some robots, not limited to movements, have multi-joint assemblies letting them simulate the movements of human arms. These joint sections must have a high swing accuracy and high rigidity ensuring that sudden stops do not put them off-track, lyjw unique products are powerful and small enough to meet those demands....
Providing tunnel boring machine manufacturers with rugged, precision slewing ring bearings is a challenge nearly as big as the bearings themselves. Our experienced engineers specialize in custom designs for hard-rock or soft-rock machines, from main cutterheads and segment erectors to screw conveyors. All designs combine performance and technical efficiency with cost-effectiveness, and are proven with static and dynamic evaluation....
Manufacturers of road rollers and compactors aim for high-speed, high-quality compacting, which requires high vibration. By meeting these specific demands, Thanks to latest technology calculation, design is permanently optimized to follow our customers new developments, in order to offer what the market needs....
