FB092 series bronze rolled bushing is our new generation bushing based upon steel-bronze lead double metal bushings. This product is widely applied overseas, With the increase of our country`s introduction of foreign machineries, designer`s require-ments on new abrasive materials and bushings are accordingly increasing. Therefore, our products see a wide application scope and practical value in machinery production.
The major feature of FB092 series bushing is their thin-wall structure, which doesn`t take up too large assembly space. Specially formulated high-density bronze alloy bands are used for the building of the bushing, whith, compared with traditional bushings, is featured in the high density,no shrinkage blowholes, high load sustainability and anti-wearing and anti-fatigue. The production of the bushing is by means of advanced fixture and molds, able to make oil holes, hole dents and grooves on the frication surfaces of the bands to suit various engineering applications, making it possible for the bushing to store large amount of lubricating grease when working, Therefore, the lubrication interval is prolonged and the service hours are effectively lengthened. FB092 series bearings are widely used in applications such as agricultural machineries,construction machineries, engineering machineries and automobile industry. |
|
| The advantages of FB092 series products are: |
1． Saving large amount of bronze material and save the working hours normally apent for lathing the bronze bushing.；
2． Compared with lathed bushings and roller bearings, it is lights and more cost-effective；
3． Various holes and dents can be made on the frication surface for grease storage, prolonging the lubrication interval to 5 times as long as required by the bronze bushing；
4． Extremely high load sustainability, especially suitable for coarse abrasion surfaces。 |
