Metal and Bimetal Bearings - VIIPLUS Bearing Technology
VIIPLUS bearings can be made in many sizes and forms, including thin-walled, thick-walled, flanged, cylindrical, sintered and oil-impregnated, and more. Some popular bearing materials and their benefits include:
VIIPLUS offers a broad range of sizes, forms and materials in monometallic and bimetallic bearings. Bimetal and metal bearings offer excellent corrosion resistance in industrial outdoor applications and in water, marine and offshore environments.
Friction welded bimetallic bearing is an important part of construction machinery, which is formed by friction fusion welding of bimetallic rolling bearing and bimetallic gasket.The product USES copper alloy in the contact sliding part with the shaft, which can play a good role in lubricating and protecting the shaft and shaft shoulder. The back lining USES steel, which has a stronger bearing capacity and further reduces the material cost.
The product can bear both axial and radial loads when used, and is suitable for rotating, swinging and other occasions of medium, low speed and high load. It has been widely used in various construction machinery site parts, such as bulldozer, excavator, conveyor, etc., supporting wheel, guiding wheel and supporting sprocket wheel.
Bimetal sliding bearings are made from bronze and steel alloy. The soft bronze inner layer can provide good lubricating performance with oil grease, hard steel back can provide good support on the whole bearing and cut down the cost.
These bearings are primarily used for bearing arrangements where heavy loads have to be supported and where rotational or oscillating movements are relatively slow.
Why choose bimetal bearing?
Minimum wall thickness, minimum space requirements
Accommodation of heavy loads
Wide range of temperatures
Good sliding properties
Virtually no stick-slip
High wear resistance
These bearing can applied with precision machining tooling
This bearing is the kind of Flange bush with the steel backing sintered with bronze powder through the friction welding. The surface may be incorporated with various kinds of oil grooves, pockets to meet different necessities of various lubricating conditions.
This product is widely applied in various automobile engines, vehicle hassis, motorcycle clutches, rubbing plate of gear pumps and other hoist machines．

is a low-maintenance composite sliding bearing, but primary lubrication is necessary. Oil or grease lubrication is possible. Due to solid lubricant storages, lubrication clearances are reduced to a minimum!
