The porous nature of the material or affinity characteristics of lubricants, lubricant infiltration bearing materials bearing installation, bearing the work period can not ad d or longer period of time lubricating this bearing as oil bearing.steel ball bearings
Oil bearing in the non-functioning state, the lubricating oil is full of the pore, the operation, the axis of rotation due to friction and heat, bearing thermal expansion of the pore decreases, so the oil overflowed into the bearing clearance. When the axis stops rotating, bearing cooling, pore recovery, lubricating oil being sucked back into the pores.
Oil bearing, although there are likely to form a complete film, but the vast majority of occasions, this bearing is in the incomplete film of mixed friction state.angular bearings
Can take advantage of the porous material characteristics of the lubricating oil is full of pores oil bearing bush material: wood, the growth of cast iron, copper alloy and powder metallurgy antifri ction materials; can take advantage of the affinity characteristics of the materials and lubricants, lubricants dispersed in The materials in the oil bearing bush material, polymer, such as oil phenolic resin.angular contact bearings
