 VIIPLUS Developed high wear resistance, dust resistance, high strength self-lubricating bearing, not only solve the problem of lubrication and reduce the noise to extend the service life, especially in bad mines, field work equipment, such as excavator big arm bearing, chassis walking mechanism, hydraulic cylinder oil pump.


Engineering machinery
Especially equipment operating in harsh mines and fields;Such as excavator arm bearing sleeve, bulldozer copper sleeve, chassis walking mechanism, hydraulic cylinder oil pump.VIIPLUS developed shock-resistant, dust-resistant, high-strength self-lubricating bearing, which not only solves the problem of lubrication but also reduces the noise and extends the service life.



Industrial machinery application
VIIPLUS bearings have the advantages of extremely low maintenance frequency and little or no oil, plus the performance of reducing running noise, even in the case of no oil supply, its excellent wear resistance can make the equipment stable operation, thus providing an economical and effective solution for the continuous safe operation of industrial equipment.Nowadays, modern chemical industry is more and more demanding for high efficiency and high precision. Meanwhile, environmental protection and safety guarantee have become basic requirements.

Structure Characteristics and Applications
VSB-50 Solid Lubricating Bearing is produced by strengthening brass that has good physical performance and good capability for casting. What's more, the brass material has pretty good anti-erosion abitity in air, fresh water and sea water. The surface is regularly and finely machined with sockets in which particular solid lubricant is filled. The product is widely used on consecutive casting and rolling machines, mine-exploiting equipments, ships, steam engine, etc.

Solid Lubricant Casting Aluminum Bronze Bearings Bushings


with Solid Graphite Lubrication. Various material specifications, standard and special shapes are also available

VSB-50  Solid lubricating bearings
1. May work without any ol for long period
2. Extremely high load capacity, good anti-wear and lower friction
3. Particularly appropriate for low speed and high load
4. Suitable for reciprocating, oscillation or intermittent motion where oil film is hard to be formed
5. Good chemical resistant and anti-corrosion characteristics
6. Can b€ used in wide range of temperature from -40℃-+300℃



VSB-50 SOLID LUBRICANT SLIDING BEARINGS material is made of strong cast bronze based metal with special solid lubricants embedded. The base metal withstands high load and the solid lubricants provide self-lubrication. The bearing shows excellent performance without pre-lubrication under conditions of extreme high/low temperature with low speed. This material provides a maintenance-free bearing solution, particularly for high load, intermittent of oscillating motion.
