YDTech® manufacturers of cross rolling elements for CNC linear guideways,linear guide rails, linear guide block! suppliers of cylindrical crossed rollers for linear slides,rotary tables, guide rails in china.
cross rollers, in the context of linear bearings, guideways or linear guide rails refer to a specific type of cross rolling element used in linear motion systems. crossed rolles in linear bearings are designed to provide high rigidity, accuracy, and load capacity in linear motion applications. these bearings use cylindrical cross rollers arranged in a crossed pattern between the inner and outer raceways.

the design of cross rollers allows them to handle loads in multiple directions, including radial, axial, and moment loads, making them suitable for applications where precision and stiffness are critical. The crossed arrangement of the rollers provides increased contact points and helps distribute the load evenly, reducing stress concentrations and enhancing the bearing's performance.
the cylindrical rollers are then inserted into the guide rail and arranged in a specific pattern, such as a V-shaped or U-shaped groove, to provide the desired linear motion. The rollers are usually preloaded to ensure consistent contact between the rollers and the guide rails, which helps to reduce friction and improve precision.
