The precision NSK bearing rolling body is very critical, because it is the direct guide body of rolling, and its rotation stability, balance performance and coordination performance have a great influence on the overall accuracy of the bearing. The error between the rolling elements of general precision bearings is between 0.002-0.003 microns. 1) Ball bearings--the rolling body is spherical. This type of bearing mainly includes deep groove ball bearings, self-aligning ball bearings, and angular contact ball bearings. The precision of the first two types is relatively low, and they are generally at the P5 level, but the latter The precision is very high, P4 level products are common, and higher level products have P2 level. High-precision products are mainly used on machine tool spindles. 2) Roller bearing - the rolling body is a cylinder. The main types of bearings are: cylindrical roller bearings, needle roller bearings, tapered roller bearings, and spherical rollers. There are cylindrical roller series and tapered roller series designed for precision products, and the accuracy requirements of the other two types are general. Mainly machine tool accessories, this type of bearing rotates stably and can withstand high speed and load. The number of NSK bearing rolling elements has a great influence on bearing performance. Single-row rolling element products are mainly used to ensure the speed of the bearing, which can bear a small load; double-row or multi-row rolling element products are mostly used in high-load equipment, and the speed requirements for bearings are very low. Double-row and multi-row bearings are mainly used in steel mills and metal smelting units, where the working environment is harsh and the load is heavy. 1) Single row bearings - bearings with one row of rolling elements; 2) Double row bearings - bearings with two rows of rolling elements 3) Multi-row bearings - bearings with more than two rows of rolling elements, This type of bearing can also be called rolling mill bearing, which is mainly used in rolling mills of steel mills. The steel has high strength, good toughness, and strong fatigue resistance, and is suitable for high-strength working conditions. NSK bearings with adjustable center structure are widely used. Because they can automatically adjust the clearance, they are mainly used in equipment with harsh environments, large vibrations, large loads, and large clearance changes. When the bearing vibrates greatly during use and the load is large, the clearance is easy to change. When this happens to non-adjustable products, the temperature of the bearing will be abnormal and the temperature will rise rapidly, and even the phenomenon of clinging will appear. 3) Self-aligning bearings - there are mainly two types, self-aligning ball bearings and self-aligning roller bearings. These bearings are generally equipped with locking sleeves, which are convenient for bearing pre-tightening, reduce the looseness of bearings and shafts, and ensure that the bearings are centering function.
