Following the development of the society; the bearing has become more and more divided into the main stream. The bearing oil has played an irreplaceable effect. The following is a specific answer to the bearing oil supplied by the bearing trading network; for reference.
Spindle bearing oil is a special smooth oil for fine machine tools and similar equipment spindle bearings; it plays an important role in ensuring the working accuracy and function of the spindle; extending its service life; also known as bearing oil.
Its main functions:
1. Outstanding smoothness is to maintain a uniform oil film between the main shaft and the bearing contact surface; and the oil film is not damaged when the main shaft starts or stops the impact load; the outstanding smooth function plays a role in reducing conflict and conflict heat. The effect of lowering the temperature rise of the spindle and ensuring the machining accuracy; the demand has an outstanding smooth function.
2, the appropriate viscosity and outstanding viscosity temperature characteristics so that the machine tool spindle temperature is not too high, so that the machine tool thermal deformation; affect the machining accuracy or make the bearing smooth; should be based on the spindle bearing layout, speed and bearing clearance, etc. Smooth oil requires excellent viscosity-temperature characteristics; avoids changes in spindle operating temperature and ambient temperature; viscosity changes are too large and affect its smooth function.
3, outstanding rust resistance because the oil can not be mixed into the air in the process of the spindle smooth system operation, or the machine coolant; therefore, the oil requires excellent rust resistance 4, outstanding oxidation resistance machine tool When the spindle is used in the cycle smoothing method; the spindle bearing oil is required to be used for a long time without being transformed, so it is required to have excellent oxidation resistance.
