It's used in vehicle chassis, forming machine tools, steel metallurgical machinery, mineral mountain machinery, hydraulic industry and rolling steel industry, etc.

 

Structure Characteristics and Applications


VIIPLUS Boundary Lubricating Bush

 

VSB-20 series is designed for marginal lubricating bushing. It is backed with copper-plated steel with porous bronze sintered on it and polymers (POM) imbedded into the bores of the bronze. The steel back provides the products with high quality low carbon steel. Oil dents stamped on the surface of the polymer can achieve good lubrication between the bushing and its mating axis. It is of good anti-abrasion and load capalility. The plating coating on the surface is erosion protective. And it is environmental protective as no lead included in the surface polymer POM. Products of VSB-20 series are widely used on automotive chassis, forging machines, mine quarrying machines, metal melting and casting machines and in water irrigating and steel rolling industries.
 
tri-layer low maintanence plain bushing have a base of lower carbon steel, onto which a porous bronze layer is sintered. Acetalcopolyer (POM) is impregnated into the intersice of this bronze layer after rolling process completed. Lubrication indents are stamped into this layer. POM has good physical & mechanical properties, also has certainly chemical properties. This material has good machining performance if required.
 
Wrapped Acetal Lined (low-maintenance), oil or grease lubricated bearings, carbon steel shell with sintered bronze layer with a co-acetal polymer layer, plain bearings, thrust washer and strip

Characteristics


VSB-20 Boundary lubrication bearing High Quality DX Bushing POM Bush China Manufacturer

  • marginally lubricated bushings for grease or oil lubricated applications

  • Standard parts contain grease indents in the sliding layer; plain sliding layer available by request

  • Optimum performance under relatively high loads and low speeds

  • Suitable for linear, oscillating and rotating movements

  • Wide range of parts available from stock

Suitable for rotating and oscillating movement, less maintenance requirements due to the long re-lubrication intervals, lower wear, lower susceptibility to edge loading, no absorption of water and therefore no swelling, good damping behaviours, good resistance to shock loads.

 

Strusture

 

1. Self-lubricating Layer POM 0.3-0.5mm. After rolling process completed, POM are filled in intersice of bronze layer, lubrication indents are stamped, which are full of oil grease, which will be removed and transferred on the mating surface, forms a physically lubricating film, which will reduced the firction and protect the mating shaft.
2. Porous bronze layer; The layer provides bonded strength of Self-lubricating Layer.
3. Steel Backing The layer provides load & thermal conductivity
4. Copper / Tin layer.

Typical Applications
 
Recommended for applications involving intermittent operation or boundary lubrication... Automotive: suspension joints, kingpin assemblies and stub axles of trucks, automobile driving joint hinges, steering and other linkages, articulation joints, rear chassis hinges, fair leader rollers... Machine tool building industry: spindles in drill, grinding, and milling machines, ram guide plates in multi-ram 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... It is especially well-suited for applications where lubricant can not be supplied continuously or repeatedly.
