Rubber-coated bearings, in the case that the existing national standard bearings cannot meet the needs, in order to achieve certain application purposes, the outer shell of the bearing is glued. At present, there are two types of rubber-coated bearings, one is outsourcing hard rubber, the other is outsourcing Soft glue. Hard rubber is a layer of plastic on the outside of the bearing, mostly engineering plastic nylon, polyoxymethylene, ABS, etc. After encapsulation, the outside is flat, with U-shaped groove, V-shaped groove, or spherical surface. There are more soft polyurethane PU. Products are widely used in industrial machinery and equipment, conveyor equipment, door and window furniture hardware pulleys, etc.

  Storage method of rubber-coated bearings:

  1. As long as the relative humidity of the storage room does not exceed 60% and the temperature changes little, the bearing can be stored in the original packaging for several years.

  2. Sealed bearings or bearings with dust covers, after long-term storage, the lubricating characteristics of the grease filled in the bearings may be reduced. The storage room should also be protected from vibration and shaking.

  3. Bearings not stored in the original packaging should be properly stored to prevent corrosion and contamination.

  4. When storing large rolling bearings, they can only be placed flat, and the sides of the inner and outer rings are best supported.

  5. If stored upright, the inner and outer rings and rolling parts are heavier, and the inner and outer ring walls are relatively thin, which may cause permanent deformation.
