Quality Management System Certification for Bearing Manufacturers GB/T40X BT Brands GB/T38X (155 ° C) EU CE Producer EU CE Certification Industrial Grade Technical Specification for Motor Bearings.

The edge of the bearing, that is, no gasket, no bearing, no lubrication engine parts, is the world's leading bearing lubrication certificate engineering, and the standard quotation patent of spare parts suppliers.

Poor interference fit between the inner ring of the bearing and the shaft/outer ring may cause the overall bearing to overheat and generate heat.

Another situation is that when two bearing sleeves or other mating clearances of the inner ring are together, such as accuracy, sound, vibration, etc., it may cause interference fit faults. The interference fit clearance between the bearing and the shaft or outer ring is too small, resulting in heating or other phenomena.

For multiple axial displacements through this method, the relative displacement value between the inner and outer rings should cause the bearing to heat up. The contact area shall not exceed 57%, and the maximum length shall be 30-50mm. For bearings with small clearance, there is a large interference fit between the bearing and the equipment bearing sleeve, resulting in insufficient interference fit.

In addition, there are three reasons: firstly, the bearing sleeve or inner ring interference fit is too tight or has failed. Secondly, there is a gap between the bearing cover and the bearing ring itself, such as incorrect fitting area and installation direction; The second is that the bearing clearance is too large or too small.

If the bearing runs for too long, it will lead to the loss and damage of the motor bearing lubricant, and the lubricant of the bearing will fail.

Excessive lubricant loss can affect lubrication effectiveness. In addition, the replacement of lubricants is also related to methods. In order to maintain the fluidity of lubricants, starting from static lubrication and gradually checking, if any abnormalities are found, they should be replaced in a timely manner.

Excessive foreign objects can cause friction between the stator and rotor, causing the stator winding to collide with the shell and causing overheating of the stator winding.

In extreme temperatures, if choosing oil-free bearings or solvent free bearings, please choose special high-temperature resistant lubricating grease.

Explanation of motor temperature measurement method: 1. When not used for outdoor work, please check the motor junction box, windings, and winding ends to see if the wires are too thin< Eod>.
