Precision Crossed Roller Bearings for the Industry 4.0 Era


With the advent of Industry 4.0 era, intelligence and automation will become the core force of the world’s industrial development.

Industrial robots and robotic arms will replace manual labor to the greatest extent, pushing the wave for industrial development.

Precision crossed roller bearings will shine in this field in this era.


Precision crossed roller bearings are characterized by cylindrical rollers moving vertically through shims on a rolling surface with 90 V-grooves.

Therefore, crossed roller bearings can withstand radial loads, axial loads, moment loads and other multi-directional loads. Compared with the conventional combination of thrust bearing + radial centering bearing, the crossed roller bearing is compact and small, simplifying the design of the rotary table and thus reducing the cost of the rotary table.

In addition, the rigidity and precision of the rotary table are guaranteed due to the high rigidity of these bearings thanks to the use of optimized preload. Thanks to the design of two rows of crossed rollers, the effective span of the bearing can be significantly increased, so this bearing has a high anti-tip moment. Among the crossed roller bearings, there are two types: the first one is crossed cylindrical roller bearing and the second one is crossed tapered roller bearing.

Precision crossed roller Bearings for the Industry 4.0 Era

Generally the price of crossed cylindrical roller bearings is lower than the price of crossed tapered roller bearings, which is suitable for rotary applications with relatively low speed; while crossed tapered roller bearings adopt the pure rolling design of tapered rollers, which has the advantages of high running accuracy, strong speed, reduced shaft length and low machining cost. Crossed roller bearings are suitable for various types of vertical or horizontal boring machines, as well as vertical milling machines, vertical lathes and large gear milling machines.

Although the crossed roller bearings have a special structure, the production and processing process is relatively tedious and has a certain pursuit for the operator. Relying on the advantages of the new equipment, the mass production capacity is quickly formed, the production cycle is quickly improved, and the cost is significantly lower than that of rotary bearings. For users, the cost performance is much higher than conventional bearings, which is the main reason why precision crossed roller bearings have gradually replaced conventional bearings in recent years.

From the beginning of the import of THK,IKO precision crossed roller bearings, to now completely localized, precision crossed roller bearings domestic technology has been fully mature, can completely replace imported products, for domestic enterprises, greatly reducing production costs.

At present, our company produces RA,RB,RE,RU,CRBH,SX,CRBT,CRBS series crossed roller bearings with high precision, high rigidity, reasonable price and large inventory, and the products are sold all over the country and even in Europe and America, and are well received by customers.
