Wear-Resistance And Corrosion Resistance Irregular C84400 Sleeve Bearing
Product introduction
In order to avoid the stress concentration area (such as the great difference in thickness), the shaft sleeve and rubber bearing or Sialon bearing form a "lubricating pair" on vertical axial-flow pump, diagonal flow pump and deep well pump. However, in some horizontal pumps, such as the split double suction pump, the shaft sleeve plays an axial regulating role, while the packing sleeve and the packing play a sealing role together. The main reason is that wear resistance is protective, mainly wear-resistant, all belong to protection
Shaft sleeve: it generally acts as a sliding bearing. In order to save materials, the wall thickness of shaft sleeve is designed according to the axial load required by the bearing. Generally, cast copper and bearing alloy are selected. The shaft sleeve is divided into opening and non opening, which should be based on the needs of the structure. Generally, the shaft sleeve can not bear the axial load, or can only bear a small axial load. Or thrust bearing. The shaft is generally round.
Bushing: the bushing generally acts as a lining. The shaft can be of various shapes, as can the bushing. The bushing can be used to prevent corrosion, eliminate assembly clearance, etc
