How to assemble and disassemble 62 series deep groove ball bearings

62 series deep groove ball bearings are widely used in various mechanical equipment due to their simple structure, strong adaptability and low cost. Correct assembly and disassembly are key steps to ensure the normal operation of bearings and extend their service life.

Preparation before assembly of 62 series deep groove ball bearings
Before assembling 62 series deep groove ball bearings, you need to make adequate preparations to ensure that all tools, bearings and parts are in good condition. The main preparations include:
Check the bearing status: ensure that the bearing is not damaged or contaminated, and that there is sufficient lubricating oil or grease.
Cleaning work: All related parts (such as shafts, seat rings, housings, etc.) need to be thoroughly cleaned to prevent dust or impurities from entering the bearings.
Tool preparation: Prepare appropriate assembly tools, such as bearing installers, hammers, wrenches, thermometers, etc. Ensure that the tools are not damaged and used properly.

Assembly steps of 62 series deep groove ball bearings
The assembly of 62 series deep groove ball bearings mainly includes the matching of bearings and shafts, the matching of bearings and shaft seats, and the processing of lubrication and sealing. The specific steps are as follows:
Bearing and shaft matching
Check the size and finish of the shaft: The size of the shaft should meet the inner diameter requirements of the bearing, and the shaft surface should be smooth and free of defects. For equipment with higher precision requirements, the dimensional tolerance and surface roughness of the shaft need to be more stringent.
Heating the bearing: For larger 62 series bearings, better assembly effects can be achieved by heating the outer ring of the bearing. The commonly used heating method is to heat the outer ring of the bearing to 60-80°C to expand it for easy installation. Ensure uniform heating and do not exceed the recommended temperature to avoid bearing damage.
Install the bearing: Gently assemble the bearing onto the shaft to ensure that there are no scratches on the contact surface between the bearing and the shaft during installation. Avoid using direct knocking during installation, and use the installation tool to press the bearing evenly.
Bearing and shaft seat matching
Check the shaft seat size: Ensure that the inner diameter of the shaft seat matches the outer diameter of the bearing, and the surface of the shaft seat should be free of defects.
Apply lubricant: Apply an appropriate amount of lubricating oil or grease to the contact surface between the outer ring of the bearing and the shaft seat. Lubrication not only reduces friction, but also prevents corrosion.
Install the bearing to the shaft seat: Use the appropriate installation tool to gently place the bearing into the shaft seat to ensure that the outer ring of the bearing and the shaft seat fit well. When installing, avoid hitting the outer ring of the bearing directly with force. It is recommended to apply pressure evenly with an appropriate installation tool.
Sealing and lubrication treatment
Selection of lubricating oil/grease: Select a lubricant that matches the application environment. Common lubricating oil/greases include mineral oil, synthetic oil and solid lubricants. The selection of lubricants should take into account factors such as temperature, load, and speed.
Control of lubrication quantity: The lubricant should not be too much, as excessive lubrication will increase friction and heat; but it should not be too little to avoid poor lubrication effect. Generally speaking, the filling amount of grease is 1/3 to 1/2 of the bearing cavity volume.
Installation of sealing device: During installation, ensure that the sealing ring is intact to prevent dust and moisture from entering the bearing and affecting the normal operation of the bearing.

Disassembly steps of 62 series deep groove ball bearings
When the 62 series deep groove ball bearing fails or reaches its service life, it needs to be disassembled. Be careful when disassembling to avoid damaging the bearing or other components.
Preparation before disassembly
Cleaning work: Before disassembly, the work area should be cleaned to ensure that the bearing surface is not contaminated during the disassembly process.
Inspection tools: Prepare special disassembly tools such as bearing removers, pry bars, wrenches, etc., and avoid using inappropriate tools for forced disassembly.
Disconnect the power supply: For bearings in electric equipment, make sure that the equipment has been disconnected from the power supply before disassembly to avoid accidents.
Remove the outer ring of the bearing
Remove external protective devices: If the bearing has a dust cover or a seal ring, you need to carefully remove these protective devices first to disassemble the bearing smoothly.
Use a disassembler: For bearings fastened in the seat ring, it is recommended to use a bearing disassembler. Align the disassembler with the outer ring of the bearing, and then apply even pressure to slowly remove the outer ring from the shaft seat.
Avoid knocking during disassembly: During disassembly, avoid using a hammer to directly knock the outer ring of the bearing. Direct knocking may cause damage to the bearing and the shaft seat.
Remove the inner ring of the bearing
Precautions when removing the inner ring: For tight inner rings of bearings, heating can be used to help disassembly. When heating, make sure that the inner ring is heated evenly, and then use the disassembly tool to easily remove the inner ring.
Check the shaft surface: When disassembling the bearing, check the shaft surface for wear, corrosion and other problems. If the shaft surface is damaged, it should be repaired or replaced.
Cleaning and inspection
Cleaning work: After disassembly, all parts need to be thoroughly cleaned to ensure that no impurities or contaminants remain on the parts.
Check damaged parts: When disassembling, it is necessary to check whether the bearing is damaged, whether the seal is invalid, and whether the lubrication is sufficient. If damage or abnormality is found, the parts should be replaced in time.

Precautions and common problems
Prevent overheating of bearings: When heating bearings, the temperature needs to be controlled to avoid changes in the material properties of the bearings due to excessive temperature.
Use tools correctly: Use appropriate assembly tools and disassembly tools to avoid excessive force that may cause damage to the bearing.
Pay attention to protecting seals: During assembly, avoid damaging the seals to ensure the sealing effect.
