The use of SKF bearings is well known; the strength of SKF bearings is very large; for example, vehicles; if the SKF bearing is not qualified, it will form a personal safety; therefore, the SKF bearing protection is also very important; Let me explain to you the important method of SKF bearing protection for vehicles; I hope to assist you. The vehicle should work within the additional load range; if it is severe overload, it will directly lead to SKF bearing overload; it will cause early failure of SKF bearing; It is a serious problem that will cause vehicle problems and personal safety. Once the important incidents have formed, it is regrettable to be late; there is no tears when we know that we are crying; therefore, it is necessary to protect SKF bearings; Carry out; carefully check; now SKF bearings are very good quality; but the usual protection is not short. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
The SKF bearing protection of the vehicle is as follows:
1. Stop the SKF bearing from being subjected to abnormal impact loads.
2. Regularly and quantitatively add lubricating oil or grease according to demand.
3. Check the operation of SKF bearings regularly; pay special attention to the abnormal sound and temperature changes of the SKF bearing parts.
4, depending on the situation; at least every 6 months to completely replace the lubricant; and to fully view the SKF bearings,
The view of SKF bearing protection is as follows:
The first step; remove the SKF bearing from the disassembly with smoldering oil or gasoline; whether it is washed with enamel; perhaps it is a way to wash SKF bearings; we all need good cleaning and cleaning. If it is not clean, it is not as good. dont wash.
The second step; carefully observe whether the cylindrical surface of the SKF bearing table has sliding or moving surface; whether the surface of the SKF bearing has no falling off or pitting; whether the rolling element and the cage can be worn and deformed; In summary, it can be used continuously.

hydroxypropyl methylcellulose Methoxyl is White or similar to white powder, odorless No heat, chemical inertness, and not participate in the metabolism of human body.
- Used as the water retaining agent and retarder in mortar to make it has good pumpability.
- Used as adhesives in plaster, gypsum material, putty powder or other construction materials to improve its workability and extend the operation time.
- Used as paste enhancer of ceramic tile, marble and plastic decoration and reduce usage of cement.
- HPMC water retention property can prohibit too fast dry and cracking after the slurry spraying and enhanced strength after hardening.
