Introduction:

Application Characteristics:                                                                                                                                

• JF bimetallic self-lubricating bearing used high quality low carbon steel plate as base, sintered porous bronze as its surface, suitable for rotatory oscillating, reciprocating movements on the conditions of high load. Low speed, low friction,
• Well wear resistance, long lifetime and better prevent from holding-on.
• The bronze layer surface can be machined with several of grooves, oil pockets in terms of different work condition.
• The product is widely sued in mining machinery, automobile, building machinery, agriculture equipment, rolling steel industry, etc.

What is bimetal bearing?

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.

Where to use bimetal bearing?

Because of their good sliding properties and compact design, these plain bearings are particularly suitable for bearing arrangements where:

Maintenance-free operation is a prerequisite.

High strength and good lubricating required, like engine, gear pump, oil pump.

Space is limited.

Why choose bimetal bearing?

Maintenance-free operation

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
