What is the maintenance of thin-walled bearings?
1. Be careful when installing and removing bearings
Thin-wall deep groove ball bearings of different types and sizes have different installation methods and tools, some of which are mechanical or hydraulic. Here we mainly explain some common basic installation methods and precautions.
First, do not install the ball with force, which will cause local overload of the ball and the contact surface, resulting in premature failure of the bearing.
Second, do not use hard tools, such as hammers, screwdrivers, etc. to hit the surface of the bearing, which will cause the outer ring of the bearing to break or crack.
2. Cleaning of bearings
A clean use environment is very important for bearings. The surface roughness of the rotating surface and rolling element of the thin-walled deep groove ball bearing ring is about 1/10 m. If the smooth ball surface is contaminated, the impact is very serious. The lubrication layer between the rolling surfaces is usually 0.2~1 m. Particle-type impurities larger than the lubricant particle size will be excessively crushed by the rolling elements and generate local pressure in the spherical roller bearing steel, which will eventually lead to permanent material fatigue. In addition to this, the dust particles in the external environment can reach 10 m in size and can also cause damage to the spherical roller bearing. Because of this, a clean and tidy working environment is so important for bearings.
3. Bearing process inspection
During use, the operating temperature of the bearing is sensed by heat drying. If the temperature exceeds the specified limit, an alarm will be automatically triggered to prevent the occurrence of burning shafts. High temperature often indicates that the bearing is in an abnormal condition. High temperature is also harmful to the lubricant of the bearing. Sometimes overheating of thin-walled deep groove ball bearings can be attributed to the lubricant of the bearing. If the bearing rotates continuously for a long time at a temperature exceeding 125C, the bearing life will be reduced. The causes of high temperature bearings include: insufficient bearing lubrication, unqualified lubricants, impurities in them, excessive load, insufficient clearance inside the bearing, friction caused by oil seals, etc.
