Oil Free Bushing – Brass Alloy, Center Flanged
Solid Bronze Bearing is manufactured using high tensile manganese bronze plugged with solid lubricants. Basic bronze alloy material is CuZn25Al6Fe3Mn3 with graphite (SL2) plugged, we also provide widely optional choice from CuSn5Pb5Zn5, CuAl10Fe5Ni5, CuSn12, and other standards materials.
Especially our company have developed the SL4 solid lubricants for water contacting applications like jet, propeller, ship, boatyard, offshore platform, hydraulic turbine etc.
These products are mainly used in applications of high load & moderate speed. It has the ability to withstand the temperature up to 400oC. We also have the capability to develop these bushes and plates as per any specifications of our clients.
Manufacture Machined solid sliding bearings according to special requirements or in accordance with customer drawings.
Huge variety of sliding bearing materials
Bearing forms made to order: cylindrical bushes with bronze alloy according to C86300, c86200, c93200, c95300, special parts according to ISO, DIN or customer design, special alloys.
Material Structure
Material: Standard material: CuZn25A16Fe3Mn3 + Graphite.
Maintenance-free bearings with lubricating plugs
Maintenance-free bearings, flanged bushing and thrust washers with graphite plugs are suitable for heavy loads, high temperatures, vibrations and for use in corrosive environments. By using bronze alloy with specific lubricating plugs, this plain bearing can also be used in applications with salt water.
