The cross shaft (bearing), also known as the cross section, generally consists of a cross shaft and four stamped outer ring roller bearings. Each outer diameter of the cross shaft needs to be processed with high precision before it can be used as the inner ring of the bearing and is connected with the roller bearing. The needles are in contact with each other, and the needle roller bearing has a self-sealing device, which can prevent dust and grease leakage, and improve the service life of the bearing. During use, maintenance personnel should regularly inject grease and lubricate the four outer bearings through the hollow bearing of the cross shaft.

Purpose of cross-shaft bearings: Cross-shaft bearing products have the advantages of large load-bearing capacity, flexible rotation, long life, low noise, and convenient assembly and disassembly for lubrication. They are widely used in metallurgy, steel rolling machinery, mining, hoisting machinery, petrochemical industry, cement, etc. Electric power, paper making and pharmaceutical industries.
