YDTech® manufacturers of cross rolling elements for robot joint bearings, linear guides,way slides! suppliers of crossed cylindrical rollers for slewing rings, rotary table, guide rails in china.
crossed rollers as rolling elements for crossed roller bearings, a type of precision crossed cylindrical rollers commonly used in various applications, particularly in machinery and robotics. loose crossed rollersare designed to provide high levels of rotational accuracy, rigidity, and compactness.
we are professional manufacture of bearing rollers and cylindrical needle rollers. we produce rollers of diameter 0.5 mm to 60 mm. the rollers could satisfy the request of DIN 5402 G2 rollers.
the crossed roller bearings involves alternating rows of cylindrical rollers set at right angles to each other. this arrangement allows the bearings to handle radial, axial, and moment loads simultaneously, making them suitable for applications where high precision and rigidity are crucial.
the crossed roller design minimizes friction and provides high stiffness, making these bearings ideal for applications that require precise positioning and rotational movement. some common uses include robotics, industrial machinery, medical devices, and semiconductor manufacturing equipment.
short rollers for crossed roller linear guides(P,V s,Ultra-thin series) application: thin bearings, thin wall bearings, thin wall cross roller bearings, robot bearings, anti creep crossed roller linear guides, cylindrical roller linear rails, ultra thin crossed roller linear guide, linear bearings, linear motors, oneway bearings, oneway clutches, heavy load linear rails, linear rails for CNC.
