When and how to replacement LM67010 bearing ?

Due to the fact that LM67010 bearing tapered roller bearings are not long-term products, their frequency of damage is relatively high. Therefore, they need to be replaced LM67010 bearing after a short period of time to avoid unnecessary losses. However, under what circumstances do tapered roller bearings need to be replaced?
1. There is a fracture on either the LM67010 bearing cup or cone element.
2. There are significant scratches on the rolling surface, blocking edges, and rolling elements.
3. The LM67010 bearing retainer is significantly worn or the rivets are significantly loose.
4. There is rust and damage on the raceway surface and rolling elements.
5. There are serious indentations and marks on the raceway surface and rolling elements.
6. There is significant creep on the LM67010 bearing inner diameter surface of the inner ring or the outer diameter surface of the outer ring.
7. Significant discoloration caused by heat.
8. The LM67010 bearing sealed with grease has obvious damage to the sealing ring or dust cover.

To replace LM67010 bearing, you can follow the following steps

1. Remove the LM67010 bearing.
Use a puller or disassembler
Pressure unloading and pull unloading have many advantages over impact unloading, such as uniform force application, easy control of force magnitude and direction, the ability to disassemble larger parts and parts with larger interference, and the less chance of damaging parts with this disassembly method. However, unloading and pulling require corresponding machinery and tools. Pressure relief requires the use of pressure machine tools, commonly including mechanical presses, friction presses, and hydraulic presses. Pulling and unloading often use dies, which can be divided into fixed arms and movable arms, as well as two claws and three claws. The pulling force applied by the die claws should be applied to the inner ring of the bearing.

When using the oil injection method replace the LM67010 bearing, the disassembly of medium and large bearings will be safer and simpler. This method injects hydraulic oil between two conical mating surfaces through oil holes and oil grooves under high pressure. The friction between the two surfaces is significantly reduced, and an axial force is generated to separate the bearing from the shaft diameter.

2. Check the working environment to ensure cleanliness and sufficient lighting.
3. Record and take photos for reference during reinstallation.
4. Choose the appropriate disassembly method based on the type of bearing and installation position.
