1. The anti-rust function is applied to the grease in the bearing to have anti-rust properties; the function of anti-rust is mainly to see the solubility of the grease; the smooth grease which is not the same as the viscosity and the different materials; Anti-rust function; in general; grease with high viscosity and poor fat solubility is more waterproof; such oil is filled with water even in the Palin cavity; it can also form a layer of oil film that can resist against the steel surface. Bicycles have low rotational speed; oils can be selected to be slightly higher in viscosity; however, they are extremely waterproof; because bicycles are used in car washing; rainy days; off-road; often dealing with water; this makes water resistance very important; even Slightly viscous grease; does not affect the smoothness of the low transition; and once the appearance constitutes oxidative damage; the entire peeling process and aging process will be rapidly increased.
2. Mechanical stability grease will become soft when rotating at high speed; cause leakage; when there is a sensation; grease will be kneaded from the raceway; and the soap layout of the grease will mechanically disintegrate and the grease will be damaged; Out of the bearing.
3. Oil seal oil seals are the gateways that contain grease and bearings from external pollution; many bearings in the industry use only ball cages; some use metal oil seal systems; some have active refueling systems; and they are completely open; Use such bearings; otherwise, only after the first cycle of oil drying or contamination; that is, the end of life is declared; while the metal-sealed bearings can prevent pollution for a long time; and can have oil-containing effects; It is not possible to disassemble and refill the oil, or to carry out comprehensive sanitation; therefore, it is also not suitable for bicycle use; it is necessary to select the bearing for the bicycle to be used with the rubber seal; the anti-pollution function of the package is good; the oil stays for a long time; After a long period of use; pick the plastic oil seal; then carry out a comprehensive sanitation and grease replacement inside.
4. Mixed grease should never mix incompatible oils; if it is mixed with two incompatible greases; the consistency will be soft; eventually it will be damaged due to the simple loss of grease; if you don't know your bearing should use that smooth grease Then you must first remove the original oil; then add a grease to smooth.
