Solid Lubricant Cast Bronze Bearings are produced by strengthening brass that has good physical performance and good capability for casting. What’s more, the graphite embedded bearings material has pretty good anti-erosion ability in the air, freshwater, and seawater. The surface is regularly and finely machined with sockets in which a particular solid lubricant is filled. Its material is CuZn25Al5Mn4Fe3. The material of copper alloy could be changed as per the customer’s requirements.

Solid Lubricant Cast Bronze Bearings Chemical Composition:

Cu:60.0～66.0 Sn:0.20
Al:5.0-7.5 Fe:2.0-4.0
Mn:2.5-5.0 Ni:1.00
Pb:0.20 Zn:22.0～28.0

Solid Lubricating Casting Bronze Bushing Is Used In High-Temperature, High-Load, Low-Speed And Heavy-Load Occasions Including

This Solid Lubricant Cast Bronze Bearings can be used in many fields such as construction machinery joints, such as excavators, mining scrapers, rotary drilling rigs, concrete pump trucks, rock drilling machinery, hoists, port cranes, etc., as well as metallurgical Mechanical continuous casting machinery, water conservancy machinery, conveying machinery, rolling mill, bottle blowing machine, film blowing machine, crosshead clamping differential for injection molding machine, tire vulcanizing machine, trailer balance beam, vacuum switch, etc.

Cast Bronze Bearing With Graphite is a wear-resistant part in machinery and equipment, graphite embedded bearings more centrifugal casting process, the color is mainly yellow, brass material wears resistance is relatively good, the internal organization is relatively tight, and will not appear to large loosening phenomenon, the appearance looks brighter, the important thing is that its hardness is relatively high, in addition to corrosion resistance and pressure resistance is relatively strong, is the majority of mining machinery equipment on the accessories.

Types Of Solid Lubricant Cast Bronze Bearing

Bearing forms made to order: cylindrical bushes, flanged bushes, thrust washers, sliding plates, pintle bearings, half-bearings, axial and radial segment rings, self-aligning spherical bearings, customized bearing designs.

The high-strength solid lubricant cast bronze bearings are widely used. It is cast into bearing bushes and copper sleeves. VIIPLUS uses high-strength brass as the matrix and is radially embedded with ordered cylindrical polymer fillers as friction materials (usually graphite). ), its superiority is mainly due to its complementary advantages of copper alloy and non-metallic anti-friction material, which not only has a high bearing capacity, but also breaks through the limit of general bearings relying on an oil film and grease lubrication, and realizes oil-free lubrication.

The graphite-embedded bearings are easy to form a lubricating film, which greatly improves its friction and wear performance, and is stable, reliable, and cost-effective. Compared with composite oil-free bearings, it has the advantages of good machinability, high precision, strong bearing capacity, and good wear resistance.
