Bimetal Bushings Assembly, Clutch Belt Pulley Bushing

bimetal bearing is made of steel sintered with CuPb10Sn10 or CuSn6Zn6Pb3 as a lining layer.This type of bushing show its best performance among bushings made of Cu-lead alloy material in this product range.It suits most for middle speed and high impact conditions.Its application including balance suspensions of heavy-duty trucks, track roller of bulldozers,auto chassis etc.

All Sizes & Types of Bushings for Belt Pulleys, Bimetal Bushing & Bearings
 

Bushing for Timing belt transmissions
Bushing for  V-Belt transmissions
Bushing for Right-angle gearboxes
Bushing for Fixing elements
Bushing for Couplings & torque limiters
Bushing for  Sprockets – Baseplates

The bearings are intended to be pressed into housing with H7 tolerance. The inner diameter of the slide bearing will then hold tolerance H9.

Features

Steel shell backed with a lead bronze lining bearing material for oil lubricated applications. This material has high load capacity and good fatigue properties. It is widely used in automotive applications such as compressors, steering gear, power steering, pedal bearings, king-pin bushes, tailgate pivots, mechanical handling and lifting equipment, hydraulic motors, agricultural machinery etc.

 
Bimetallic bearing is made of lead-tin bronze alloy sintered on the surface of high quality low carbon steel back, which is rolled into copper and steel strip after several times of high temperature sintering and dense rolling.The product is one of the strongest copper-lead alloys and has a wide range of applications. It is most suitable for various applications such as bushes and thrust washers under medium speed and high impact loads.
 
 
Because the matrix is stable as low carbon steel material, so the machining accuracy of the outer diameter of the shaft sleeve has been guaranteed, and there is no need for screw fixation after the product is loaded into the seat hole, relying on interference fit can prevent the phenomenon of going out of the circle.The change of chemical composition of inner surface alloy layer can meet the requirements of different bearing pressure, different service temperature and different sliding speed. The oil groove and oil hole with different structure are designed in the production of friction surface to meet the requirements of different ways of oil adding, prevent shaft biting and adapt to different lubrication conditions.
Widely used in automobile engine, motorcycle clutch, light industrial machinery, construction machinery.
Alloy layer material CuPb10Sn10 or CuSn6Zn6Pb3
 

Typical Characteristics

Suitable for low speed, heavy load or intermittent movement conditions, lubricating oil film can not form or maintain the occasion;
Suitable for the working environment or mechanical structure restrictions, it is difficult to supply oil lubrication occasions;
It is suitable for rotating, reciprocating, swinging, linear and other forms of movement, as well as occasions requiring frequent starting or starting under high load;
Suitable for high or low-temperature work, or the environment temperature range of large occasions; Good corrosion resistance, can be used in seawater and other corrosive media such as chemical liquids or gases, as well as water containing sediment or the radioactive environment;
Non-water absorption, good dimensional stability, high mechanical strength, good thermal conductivity;
Bearing is a thin wall structure, lightweight, small volume, suitable for compact design;
Compared with the traditional three-layer composite material, the static load characteristics, wear-resistance, service temperature, dimensional stability, and so on under the condition of non-grease lubrication are better;
Compared with copper inlaid self-lubricating material, it is more suitable to work under the condition of small Angle swing, and the price is cheaper.

Range Of Application

 
Typical Applications
This material is recommended to be used under the medium speed and medium load condition with oil or grease lubricating. It is widely used for motor rod ends, Kingpin bushing, undercarriage rollers, hydraulic cylinder rod eyes of construction machines, and spherical joint bearings of agricultural machines. Because this material is with lead, the specific parts are not allowed to be used according to certain laws or regulations.
 
 
The products are applied to water conservancy and hydropower industry: hydraulic machinery: horizontal support slide of hydraulic steel gate, support bearing of the hydraulic hoist and closure machine, sandblasting maintenance door bearing, etc. Hydraulic turbine: guide vane shaft sleeve (upper guide, middle guide, lower guide), wheel shaft sleeve, pin shaft sleeve (connecting rod pin, push and pull rod pin, relay piston pin), anti-wear ring plate (thrust ring), anti-wear block, control ringside tile.
Metallurgical industry: die-casting machine bearing, rolling cutting shears (bilateral shears, fixed-length shears on the skateboard), etc.
Valve industry: butterfly valve, globe valve, etc.
Others: mining machinery, packaging machinery, construction machinery, heavy machinery, injection molding machine, automobile tire mold, wind turbine, thermal power, and other industries.
 

Agricultural Machine

 
As the self-lubricating bearing has the characteristics of maintenance-free and good abrasion resistance under dust and outdoor conditions, it is widely used in the cylinder, the suspension system of the combine harvester, planter, baler, crusher, tractor, Joints, and other parts can not be difficult to form oil or oil film parts.
