Product Introduction

200#B Oil-Retaining Bimetallic Bearing is a bimetallic bearing composed of a steel backing and a copper-based sintered layer (Copper Sinter), and dispersed with solid lubricants. The bearing has excellent self-lubrication, high load capacity and wear resistance, and is suitable for high-speed, high-temperature or lubrication-restricted working conditions.

Application areas:
Automotive industry: used for parts that require high load and wear resistance, such as engines, gearboxes, and suspension systems.
Engineering machinery: suitable for joint bearings and transmission parts of heavy equipment such as excavators and cranes.
Industrial equipment: widely used in rotating parts that require long-term maintenance-free, such as motors, pumps, and compressors.

FAQ 1: What are the main advantages of 200#B bearings?

200#B bearings combine the high strength of steel backing and the wear resistance of copper-based sintered layers, while solid lubricants are dispersed in them, and can work under oil-free or oil-poor conditions. Its advantages include high load capacity, low friction coefficient, high temperature resistance (up to 200°C), and long life and maintenance-free, which are particularly suitable for harsh working conditions.

FAQ 2: Does this bearing require additional lubrication?

200#B bearings are designed as oil-containing self-lubricating structures. Solid lubricants form a lubricating film during friction, so in most cases no additional lubrication is required. However, under extreme load or high-speed conditions, it is recommended to use a small amount of lubricant to extend the service life.

FAQ 3: Which industries are most suitable for using 200#B bearings?

This bearing is widely used in automobiles, construction machinery, agricultural equipment, industrial transmission and other fields. It is particularly suitable for scenes where lubrication is inconvenient or high temperature resistance and corrosion resistance are required, such as wind power gearboxes, hydraulic motors, mining machinery, etc. Its reliability is particularly outstanding in harsh environments.
