Code of rolling bearings rolling bearing, is a group of digits represent the bearing structure, type, and inner diameter size, code provisions in seven digits, commonly used is a digital, followed by a digital said the inner diameter of the bearing number;
The first digit said bearing diameter series, that is, in the inner phase at the same time, there are a variety of different diameter, can consult the relevant standards;
Said the first digit bearing type, for example, '' said centripetal ball bearings,' 'said flat thrust ball bearings.
The surface roughness of the workpiece can not meet the requirements of the main reason is:, screw air compressor host bearing is damaged, please come air compressor professional timely maintenance, workpiece speed too high or the workpiece axis and spindle vibration;
, normally, the temperature of the bearing with operation began to slowly rise,. . .
Reach a steady state after hours.
The material as a kind of high-tech functional materials, the future can not only change the way the user maintenance, and make the maintenance more simple, faster and more efficient, more economical, more environmental protection, equipment, long cycle life.
After grinding the material through the hollow shaft neck, such as bearing pressure into the shaft by hand after the rotation has obvious 'sasha vujacic' feeling, may be the shaft or shaft roundness tolerance is too big.
Bearing bearing type selection: bearing type, is used by user's technical personnel according to the product of form a complete set of conditions and the load bearing for selection.
Huey long mechanical small make up remind everybody to use bearing should pay attention to the time, the bearings of knowledge: bearing clearance, however, clearance is too large will change the dynamic characteristics of bearings, rotor caused by unstable operation.
Low pitting dozen pitting repair technology is a kind of emergency measures, and is limited to wear very mild, after repair of the bearing inner ring and shaft fit only for contacts, so in the operation process under the condition of large load, pitting susceptible to fatigue wear and short service life, is only a temporary emergency.
Holiday during the break to remove the rubber roller, prevent compression deformation;
, divided into rough washing and fine washing cleaning, thick wash to clean diesel oil or kerosene, fine cleaning oil for clean gasoline.
Used in the manufacture of wall thickness & amp;

Five, scratch card injury phenomenon: mm, surface roughness, accompanied by small soluble apply;
End of the ring gear edge and roller scratch called card.
Improper assembly method and trunnion bearing or bearing hole of the interference is small, use pressure into the method of assembly, more simple method is to use copper bar and hammer, way according to the order of symmetry on bearing seat with interference fit, the bearing pressure into the smoothly.
Drying cylinder bearing wear of repairing the scene analysis and case pictures one paper company workshop dryer machine in the process of long-term use, due to the damage of bearing, metal fatigue wear and run maintenance does not reach the designated position, lead to paper machine dryer section shaft appear wear phenomenon.

Methyl amino acetonitrile it can freely detached from the bearings with or without rolling body, or take to maintain and rolling element bearing ring or bearing washer, can freely detached from the bearing rolling element and cage components.
