Introduction of THK Cross-Roller Ring

The THK Cross-Roller Ring is a special type of bearing that has a split inner ring and a rotating outer ring because the inner or outer ring is split. After the rollers and gaskets are installed, they are secured to the THK Cross-Roller Rings to prevent separation from each other, thus making it easy to install the THK Cross-Roller Rings. Next, we look at the introduction of the THK Cross-Roller Ring. Here are some answers.

The application of the THK Cross-Roller Ring is very common.

THK Cross-Roller Ring is commonly used as a joint bearing in industrial robots. Because the rollers are arranged in a cross arrangement, only one set of THK Cross-Roller Rings can withstand loads in all directions. Compared with traditional models, the rigidity is increased by 3 to 4 times. At the same time, because the THK Cross-Roller Ring inner ring or outer ring is a two-part structure, the bearing clearance can be adjusted, even if preload is applied, high-precision rotational movement can be obtained. THK Cross-Roller Ring is widely used in industrial robots, working machinery and medical facilities, etc. Where high rigidity, tightness, and high speed are required to ensure accuracy.

What details should be paid attention to when purchasing THK Cross-Roller Ring?

First, size is the most important parameter. You must know how big a THK Cross-Roller Ring you need to use.

Second, because the THK Cross-Roller Ring has many structures with the same external dimensions, including outer rings and inner rings, the key depends on whether the part of the bearing to drive rotation needs to be installed on the inner ring or the outer ring of the bearing. If the outer ring is required to rotate, the inner ring type must be used; similarly, the inner ring rotation accuracy is required, and the outer ring type must be used.

Third, the THK Cross-Roller Ring is divided into two categories according to the installation method. One is that the inner and outer rings are equipped with installation holes. Like a slewing ring, its installation is relatively simple, and it is directly connected to the equipment by connecting bolts. The other is that there is no mounting hole in the inner and outer ring, mainly through the interference fit of the bearing seat and compression flange, shaft, and bearing inner diameter.

Fourth, to choose which THK Cross-Roller Ring to choose must know whether it can withstand the load imposed by the equipment, and determine whether it is suitable according to the load-bearing capacity requirements of the equipment design and the rated load of the corresponding bearing.

Fifth, the accuracy and clearance of the THK Cross-Roller Ring are the core of cross-roller bearings. The positive and negative travel of the bearing can affect the rigidity, noise, life, and speed of the THK Cross-Roller Ring. When the working clearance is negative, the fatigue life of the bearing is the longest, but the fatigue clearance decreases significantly as the negative clearance increases. However, the rigidity of the bearing can be greatly improved, and the noise of the bearing can be reduced at the same time.
