LYDZC Precision Crossed Roller Bearing Features:
1, accuracy: can reach P5, P4, P2 level
2. Rigidity: Preload is applied at the factory, which can bear radial load, axial load and overturning moment load. LYDZ bearing can replace multiple sets of combined bearing.
3, load: linear contact, the number of rollers is large, with a very high carrying capacity
4, space: miniaturized cross-sectional size design, saving installation space, small size, light weight
5, movement: smooth rotation, stable friction torque
6, installation: easy to install and adjust
7, model: a variety of bearing types and size series to choose from
8, design: can provide customized design and production
