Bimetal bearing features:
Excellent anti-friction and wear resistance: bearing alloy layer can effectively reduce the coefficient of friction, reduce wear, extend the service life of bearings and shafts.
Good bearing capacity: the steel backing can withstand large loads, so that the bearing is suitable for heavy load conditions.
Good compliance and embedding: the bearing alloy layer has a certain elasticity, can adapt to the slight deformation of the shaft, and embedded foreign impurities, reduce the wear of the shaft.
The cost is relatively low: compared with some high-performance bearings, bimetal bearings have a higher cost performance.
Bimetal bearing application:
Bimetallic bearings are widely used in various mechanical equipment, especially in the following areas:
Internal combustion engine: crankshaft bearings, connecting rod bearings, etc.
Construction machinery: transmission system, walking system, etc.
Metallurgical machinery: rolling machine, continuous casting machine, etc.
Marine machinery: propulsion system, deck machinery, etc.
Other fields: compressors, pumps, machine tools, motors, etc.
Types of bimetal bearings:
According to the different materials of the bearing alloy layer, bimetal bearings can be divided into:
Babbitt bimetallic bearing: has good anti-friction and embedding properties, but the bearing capacity is low.
Copper base alloy bimetal bearing: has a high load capacity and wear resistance, but slightly poor anti-friction.
Aluminum base alloy bimetal bearing: light weight, good corrosion resistance, but low load capacity.
The development trend of bimetal bearings:
Development of new bearing alloy materials: Development of bearing alloy materials with higher wear resistance, corrosion resistance and high temperature resistance.
Application of advanced manufacturing process: Advanced manufacturing processes such as precision casting and powder metallurgy are adopted to improve the manufacturing accuracy and performance stability of bearings.
The development of composite structure bearings: The development of bimetallic bearings with multi-layer composite structures to further improve the comprehensive performance of bearings.
In short, bimetallic bearing is a type of plain bearing with excellent performance and wide application, which plays an important role in the machinery industry.
