Under normal circumstances, the general purchasing SKF bearings will have excess inventory, unreasonable storage place causes the SKF bearing failure deformation. How to SKF bearing reasonable storage placement is a very important work. Note technician today Delik Qingdao Bearing Co., explain in detail for you SKF bearing storage place.
In principle, all SKF bearings should be kept in their original packing before installation. They need to stay in a clean, free of moisture, relatively constant temperature environment. Oil-free bearings should be kept away from water and dust, corrosive chemicals. Mechanical shaking and vibration will always be possible damage to the SKF bearings, must therefore avoid the vibration in the process of handling and storage.
Basically, all SKF bearings must be the level of preservation, because the oil bearing long time placed vertically without some heavier, can be deformed by its own weight.
Pre-coated with grease ( or seal ) SKF bearings need to be especially careful, because the grease after the density change after long time storage. So when the bearing is used for the first time, there will be a certain degree of rotation noise. Therefore, the bearings should be set aside time to control the FIFO principle.
( 1 ) in the radial direction and axial direction axial decided to correct the position at the same time, jitter suppression shaft.
( 2 ) increase the rigidity of the bearing. Oil-free machine tool spindle bearings, bearing by differential pinion.
( 3 ) to prevent axial direction vibration and abnormal sound due to resonance. Small electric motor bearings.
For radial spherical plain bearings subjected to combined loading, due to the increased number of rolling bearing load, friction increases, have a fever increased, lubrication and cooling conditions worsen, and force a cage is also increased, therefore, must be based on SKF, bearing type and load angle, there will be no oil bearing the speed limit is multiplied by a reduction factor F2 to swap.
If the requirements of speed limit speed can not be satisfied with the application of selected SKF bearing, can use some ways to improve the skills to progress, to meet the request of the. Such as increasing the oilless bearing tolerance level; appropriate increase clearance; use special information and improved stick frame structure; transition lubrication methods, such as oil and gas, oil mist with spray lubrication; improved cooling conditions.
