If the customer does not use the bearing temporarily after purchasing it, the bearing shall be properly kept to prevent rust and pollution. People in Correct Storage the bearing industry believe that the following aspects need to be done well:
1. Keep the original packaging and do not open it arbitrarily. If the packaging is damaged, it must be opened, Correct Storage carefully cleaned and repainted.
2. The relative humidity of the storage room shall not exceed 60%, and the temperature difference shall not be Correct Storage too large. The bearings placed in the original packaging can be stored for several years. For sealed bearings or bearings with dust covers, the lubrication characteristics of the grease filled in the bearings may be reduced after long-term storage.
3. The storage room shall also be protected from vibration and shaking. The bearings not stored in the original packaging shall be properly stored. It is strictly prohibited to put the Correct Storage bearings together with corrosive things to prevent corrosion and pollution.
4. Large rolling bearings can only be placed horizontally during storage, and the sides of the inner and outer Correct Storage rings are all supported. If it is stored upright, permanent deformation may be caused due to the heavy inner and outer rings and rolling parts and the relatively thin inner and outer ring walls.
Angular contact ball bearings mainly bear large unidirectional axial load. Correct Storage The larger the contact angle is, the greater the load bearing capacity is.
Cage materials include steel plate, brass or engineering plastics, and the forming methods include stamping or turning, which can be selected Correct Storage according to the bearing form or service conditions. Others include combined angular contact ball bearings, double row angular contact ball bearings and four point contact ball bearings.
The larger the contact angle, the higher the axial bearing capacity. High precision and high-speed bearings usually have a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase. Single row angular contact ball bearings can only bear axial load in one direction, which will cause additional axial force when bearing radial load.
And can only limit the axial displacement of the shaft or housing in one direction. If it is installed in pairs, make the outer rings of a pair of bearings opposite, that is, the wide end face to the wide end face, and the narrow end face to the narrow end face. In this way, additional axial force can be avoided, and the shaft or housing can be limited to the axial clearance in both directions.
Because the raceways of the inner and outer rings of angular contact ball bearings can have relative Correct Storage displacement on the horizontal axis, they can bear both radial load and axial load – combined load (single row angular contact ball bearings can only bear axial load in one direction, so they are usually installed in pairs).
Cage materials include brass, synthetic resin, etc., which are distinguished according to bearing form and service conditions.
The technique of selecting grease for angular contact ball bearing. Grease is a stable solid or semi-solid product composed of dispersing thickener in liquid lubricant, in which additives and fillers aimed at improving some characteristics of grease can be added.
The grease can be attached to the vertical surface without loss at room temperature, and can work in open or poorly sealed friction parts. It has a holding point that can not be replaced by other lubricants. Therefore, grease is used as lubricating material in many parts of automobile and construction machinery and angular contact ball bearing parts.
