1. The basic requirements of the lubricant
Usually lubricants have the following basic requirements:
(1) has a sufficient lubricating effect, i.e. to reduce the bearing friction and inhibit the process of the skf bearings harmful wear, the frictional resistance to be small, abrasion resistance to a large.
(2) prevent the bearings rust itself does not cause the cause the fag bearings component parts (such as copper cage, corrosion, deterioration or deformation of rubber seals, etc.).
(3) within the predetermined upper and lower limit of the working temperature range, and always maintaining the necessary lubricating properties, chemical composition and stability, little change in viscosity.
(4) in the upper and lower limits of the range of the predetermined operating speed, can establish a sufficiently thick film; itself clean and free of impurities, good defoaming properties.
(5) in the required period of work or inventory period, physical properties and chemical properties, is sufficiently stable, will not produce affect the use of lower quality.
(6) Maintenance, maintenance and strive simple attachment as little as possible.
(7) under the premise to meet the technical requirements of the economy and strive to savings.
2. Additional requirements for lubricant
(1) has a good cooling effect.
(2) the lubricated surfaces have a strong adhesion, leak, drip or rejection scattered as less as possible; water separability.
(3) mixed with a little impurities (such as water, etc.) without affecting its proper performance.
(4) sealing effect, to prevent water or dirt into the bearing.
(5) difficult to transmit vibration, or can reduce the noise.
(6) to implement centralized lubrication.
3. The special requirements of the lubricant
Of lubricant in the special conditions, the following special requirements:
(1) the requirements of the long-life requirements the life of the lubricant is particularly long.
(2) the requirements of low frictional torque requirement low frictional resistance of the lubricant.
(3) the requirements of high temperature requirements resistant to temperatures above 250 ℃.
(4) The low temperature resistant Requirements resistant to temperatures below -63 ℃.
(5) resistant to high vacuum Requirements under high vacuum conditions, the non-volatile, does not dissipated, without deterioration, particularly in a weightless state under high vacuum conditions.
(6) harmless requirements
Used in the food, pharmaceutical, chemical machinery, require even less micro-lubricant mixed with food, medicine or chemical products, it will not cause food poisoning, drugs modified metamorphism or chemical products.
(7) The boundary lubrication characteristics of good requirements
Coal and other pollution in the larger environment, mixed with The solid impurities lubricant film damage and often in boundary lubrication, the lubricant can adapt to such conditions.
