JDB Graphite Lubricating Bronze Bushings
►Graphite filled bronze bushing
We manufacture and export a huge range of Graphite Filled Bushes,bearing pads,thrust washer. High Tensile Manganese Bronze from the quality material of bronze. These High Tensile Manganese Bronze are used in various industries.
The product is manufactured using high tensile manganese bronze, efficiency machines and innovative techniques. These products are mainly used in applications of high load & moderate speed. It has the ability to withstand the temperature up to 650oC. We also have the capability to develop these bushes and plates as per any specifications of our clients.
►Material:
Standard material: CuZn25A16Fe3Mn3 + Graphite
►Characteristics:
♦ Have Incomparable performance under a high load, low speed operation. Also perform well without lubrication,
♦ Excellent wear resistance in such places where an oil film is difficult to be formed due to reciprocating, oscillating motions and frequently intermittent operations
♦ Remarkable resistance to corrosion and resistance to chemical attack
♦ Maintenance free and save operating cost.
►Availability:
♦ Cylindrical oiles bushing, flanged oilless bush, thrust washer and slide plate are standard fabrication.
♦ Special designed solid metal bearing and material can be made according to your design.
♦ Other material can be made based on your requirement.
►Application:
JDB solid brass bearing is widely used in successive casting machine, mineral mountain machinery, shipping, steam turbine etc
