JF series material, also known as bimetallic material or copper lead steel belt, is a steel and copper alloy product with low carbon steel plate or steel coil as the matrix material and surface sintered copper alloy. Different copper alloy materials are suitable for different working conditions. According to the different grades of surface copper alloy, it can be divided into high lead series, lead-containing series and lead-free series.

VIIPLUS bimetal bearings take steel backing as base The bearings are sintered with CuPb10Sn10, CuPb24Sn4, CuPb30,  after press. It can insure the bearings O.D. Precision against the friction between O.D. And housing after pressing it into housing because of mild steel as its base. The chemical changes of inner alloy layer can make the bearings work well under various load presses, different working temperatures and sliding speeds. Different structures of oil grooves and oil Indentations can satisfy different adding oil ways and prevent the bearings from gripping shaft.

Parameters

JF series materials, also known as bimetallic materials or copper lead steel strips, are made of low carbon steel or steel coil as the base material, and the surface is sintered with copper alloy steel and copper alloy products. Different copper alloy materials are suitable for different working conditions. The surface copper alloy grades can be divided into high lead series, lead series and lead-free series.

In order to fully lubricate the bush when in the performance, the indentations with size as follows are recommended.
They should be manufactured according to the standard below if without special requirements.
The lubricating hole should be away from butt joint and loading aera and designed to be easy-oil-feeding as well.

Bimetal bushing Application

Bimetal bearings are widely used in oil lubricating situations. Normally under lowspeed and oil lubricating situations assemble with grease and work with adding oiI Periodically, such as suspension, steeping ball joints, brake pedal points, redirector, connecting rod, slide part of punch, construction and earth-moving equipment. etc. Under middle speed work with oiI, such as connecting rod, shaft and transportation parts of cut machine. Under high speed work within oiI, such as gear box, fuel pump, engine, clutch. etc.

Bimetal Bushings are widely used in various parts of automobile industries such as engines, transmission cases, vehicle chassis, steering knuckle, trunnion shaft, leaf spring, motorcycle clutches, wear plating of gear pumps,as well ashoisting machines, etc.
It is backed with high quality low carbon steel with bronze alloy sintered on its surface. To effectively decrease abrasion, its alloy surface can be machined with ball shaped oil pockets for easier oil storage. When necessary, an anti-corrosion coating can be plated on the steel back. It can be applied to conditions of mediate load with mediate or high running velocity and conditions with enormous impact load. Such as internal combustion engine bearing,connecting rod bearing, rock arm bearing, slide plate of oil gear pump and etc

BIMETAL BUSHINGS INSTALLING METHOD

1. To keep the bushing, housing dean before installing.
2. The outside surface can be covered with a little grease or oil during installing, which help the process.And please not too much.
3. The bushing should be pushed into housing slowly with mandrel (oil push machine is recommended), it is for hidden to hammer
the part directly.
4. We need your instructions if the housing wall is thin or made from soft metal in order not to destroy it.
5. In order to simply the installment and keep the working layer, we recommend that the shaft should own chamfer and
HRC45/RZZ-3. Gr plating layer is allowed.
6. Grease and Oil are recommended in order to shorten the mending.

CHECKING METHOD

1. OD, checked by ring gauge with GO/NO GO
2. ID, checked by plug gauge with GO/NO GO. The common wrapped bushing satisfy tolerance H9.
3. The size of ring gauge & plug gauge are in comply with DIN1494 part 1.

Bearing forms available in standard dimensions
· Cylindrical bushes
· Flanged bushes
· Thrust washers
· Flanged washers
· Sliding plates
Metric bearings and imperial bushings made to order: standard bushing forms in special dimensions, half-bushings, special shapes obtained by stamping or deep drawing, customized bushing designs
