The grease used in the bearing must have an anti-rust effect, and the anti-rust agent should preferably be insoluble in water. The grease should have good adhesion and can form an oil film on the steel surface, which can be maintained even if the grease is filled with water.

1. Anti-rust performance

2. Mechanical stability

Grease softens when machined, causing leakage. When there is vibration in the application example, the grease will be thrown from the bearing seat into the bearing. If the mechanical stability of the grease is not enough, the grease will be continuously thrown out of the bearing, which will cause mechanical disintegration of the structure of the soap and the destruction of the used grease.

3. Oil seal

Oil seals are necessary to protect bearings and lubricants from external contamination, and neither debris nor moisture can penetrate into the bearings to prevent damage. Correct installation and maintenance is an important factor for the longest service life of bearings. At the same time, attention must be paid to the cleanliness of the bearing, the correctness of the bearing selection and the selection of appropriate installation and maintenance tools. Bearings must be protected from contamination and moisture and must be properly mounted and lubricated. The design of the bearing arrangement, the condition of the oil seal, the type of lubricant and the lubrication cycle, as well as special maintenance all play an equally important role.

4. Blend oil

Never mix incompatible fats, if two incompatible fats are mixed, usually the consistency will be soft and you may end up with damage as the oils tend to run off. If you don't know which kind of grease was originally used in the bearing, you must first remove the old grease inside and outside the bearing before adding grease.
