Double row crossed roller bearings

The double row cross roller bearings designed by MONTON Bearing can withstand loads in all directions, with high rigidity, high precision, simple structure and easy assembly, making them the most suitable rotating mechanism for composite machining machines. The double row cross roller bearing has installation holes on the inner and outer rings, and adopts a double row small-diameter roller design. The structure is simple and easy to install, and the bearing is directly fixed to the shaft or support seat through the installation holes. By increasing the number of rollers, high rigidity of the bearing can be achieved. The MRW type can specify the dynamic accuracy of the vibration bearing according to the machining position, measurement position, and actual working height position to meet the requirements of high rotational accuracy.

The processing s range of the double row cross roller bearings designed by MONTON Bearing is from the inner diameter of 100-650mm. Common models include MRW195, MRW228, MRW297, MRW445, etc. The highest precision is P2 level. The radial clearance of MRW double row cross roller bearings is adjusted to negative clearance (preload state) at the factory, which can be adjusted by the starting torque of the product. MRW type double row cross roller bearings do not have basic requirements for fitting, but when positioning accuracy is needed or the applied load is large, it is recommended to insert the shaft and support seat with a fitting tolerance of g6 and hole H7 for use. When higher rigidity is required, it is recommended to measure the inner and outer diameters of the bearing and adopt a slight interference fit based on the measured values. Before installing double row cross roller bearings, the appearance of the components should be checked, and they should be installed horizontally and locked with fixing bolts. When storing double row cross roller bearings, store them horizontally indoors and avoid high temperature, low temperature, and highly humid environments. Over time, the lubricant inside may deteriorate. Please check regularly and add lubricant before use.
