Description

Boundary - Lubrication Oilless Sliding Bearing DX Bushes for Mining Machinery (SF-2)

Boundary-Lubrication oilless sliding bearing to steel as matrix, sintered bronze spherical powder as the middle layer, the surface of rolling modified Poly oxymethylene (POM) and has storage pit.

Plastic surface of the product thickness 0.5mm, has good wear resistance, in the less oil or oil under the conditions of space off to work correctly. It was adapted to work under conditions of ambient temperature and low-speed heavy-duty venue to replace the traditional copper sets, both to reduce the cost of extending the service life. Product has been widely used in auto chassis, forging machine, metallurgical and mining machinery, engineering machinery, hydropower, steel rolling industry and other fields.

Introduction
It is made of high quality low-carbon steel, sintered porous bronze as its interlayer, with the compound of POM as its surface. And has good load capacity & wear-resistant. It's used in vehicle chassis, forming machine tools, steel metallurgical machinery, mineral mountain machinery, hydraulic industry and rolling steel industry, etc. It is without lead, can meet the requirements of environment protection.
Metallurgical structure 1.POM 0.3~0.5mm
2.Porous bronze 0.2~0.3mm
3.Steel backing 0.4~2.2mm
4.Copper plating 0.008mm

Typical Application

Recommended for applications involving intermittent operation or boundary lubrication...
Automotive: suspension joints, kingpin assemblies and stub axles of tucks, automobile driving joint hinges, steering and other linkages, articulation joints, rear chassis hinges, fairleader rollers...
Machine tool building industry: spindles in drill, grinding, and milling machines, ram guide plates in multigame presses...
Agricultural equipment: gearbox, clutch, bale trips and wheel caster swivels for bale accumulators, front axle pivot bearings, steering idler box bearings and kingpin bearings for harvesters...
Be especially well-suited for applications where lubricant can not be supplied continuously or repeatedly.
