In the General case, SKF bearing grease filling, always exceeds the amount of directly involved in the actual needs of lubrication, cavity on the frame and bearing cover, and on the edge of the rolling forming an outline. In this process, due to the resistance of excess grease, bearing temperature rise quickly. Although most of the excess grease in the early running was out, and squeezing roller attachment for grease also could still be turned between the rolling elements into the Raceway.
The initial phase of these bearings, most of the grease quickly (in less than a minute) crowding the Raceway, and piled up in the grease in the bearing rotor loop at the same time, one after another few to be discharged. Bearing temperature continues to rise until extra bearing grease is discharged so far, can be called a grease collection phase, according to the SKF lubricating grease in the bearing structure factors such as quality, quantity, which can last a dozen minutes, or even hours.
1, rust-proof performance
Rust can best do not dissolve in water, has good adhesion, can form a thin film on the surface of steel.
2, mechanical stability
If the mechanical stability of fat enough, work process, mechanical oil SOAP structure collapsed, causing oil to be destroyed, and thus lose lubrication.
3, oil seal
Oil seal is required for protection of SKF bearings and lubricants from external contamination barrier, bearing operation process, whether debris or moisture cannot penetrate the bearing, in case the cause for its destruction.
4, mixed oils
Do not mix incompatible greases, if two incompatible greases mixture, its consistency is usually softened in may end up bearing damage caused by the oil easy to drain.
5, classification of oils
Grease of consistency and lubricating ability is affected by temperature, operation at a certain temperature the bearing must be under the same temperature to select the correct consistency and good lubrication grease.
Remaining bearing grease after they have been discharged completely, leaving a small amount of grease in between rolling element and the Raceway, cage on the contact surface, film nationality wedge to form a thin layer of grease, thus entering the bearing normal phase. Temperatures gradually decline and reach equilibrium. In other words, long-term lubrication, relies mainly on this layer grease film to bear. In addition, in the long-term operation of the SKF bearing, as well as on the contour of the rolling element and the Raceway near cage grease on shrinking and ceding part of the base oil and into the Raceway after he, lubrication there is also a complementary role.
Some so-called Eddy current type of grease is not, it is difficult to form the outline, even forming contours easy to collapse, then repeatedly rolled back to Marky consistently is strong mixing condition of excess grease, torque of SKF bearings, high temperature, and uneven, and may also generate noise, also vulnerable to spoilage and loss of lubricating grease.
Different greases in bearings is not the same as the opening formed in the outline, it is important to form a draft outline, exercise time, SKF bearing temperature low in the long-term operation and smooth, this is an ideal grease, grease into drainage is particularly important.
