VIIPLUS is capable to fine tune the performance of the bronze bearings with the right choice of bronze alloy bearing material and groove design.

Bronze bushings are a maintenance-bond bearing material. Also the type of movement, oscillation or continuous rotation, will determine the choice of groove type.They need to be greased regularly, otherwise the bushing as well as the shaft will wear out very fast. It is necessary to have a sufficient distribution of grease in the high load area between the shaft and the bushing.

Oil & Grease Groove Bronze Bushings

Any of our standard stock sizes of Sleeve Bushings are adaptable to grooving and graphite plugging.

Types of lubricant groove:

Axial, Oval,Double Oval, Circular,Figure of eight, One and a half figure of eight, Double figure of eight, Duplex figure of eight

Oilless bushing advantages
1. Flexible, simple, convenient design, wide range of use;
Fuel supply system in the mechanical design is a work, time-consuming device, using solid self-lubricating bronze bearings do not need to consider when designing refueling device, save gas devices, as well as for a wide variety of special occasions, solid self-lubricating bearing design into various shapes, so as to meet the needs of a variety of special occasions, using solid self-lubricating bearings, can significantly reduce the mechanical maintenance, oil and other expenses.
2. No oil can be used;
Since solid lubricant is greater than the linear expansion coefficient of metal matrix, so when to run solid self-lubricating bearings, the oil film will be transferred to the grinding and implemented on a self-lubrication, so solid self-lubricating bearings can be used in the place where is hard to go and can’t go or grease, even in the case of low speed and high load, also can have good lubrication effect.
3. Low use cost;
The traditional mechanical design, in a certain operating time, want to often come on maintenance, check the oil, the oil supply device was clear, the body itself and the surrounding environment pollution caused by regular gas, result in an increase in maintenance costs, realize self-lubrication, not only can realize the environment clean and tidy, and greatly reduce the cost of the use of lubricating oil.
4. Under the condition of high load and low rotating speed, it can give play to superior performance;
Solid self-lubricating bearing is made of centrifugal casting high strength alloy brass substrate, have the effect of bearing load, with special formula with good self-lubricating properties of graphite lubricant, self lubricating effect, so it’s a combination of their respective advantages, even in high load, low speed, can produce superior performance.
5. Excellent wear resistance can be developed in places where the oil film is difficult to form, such as reciprocating motion, rocking motion and frequent starting and stopping;
The arrangement principle of solid self-lubricating bearing lubricants is to ensure that there are lubricants in each part of the grinding part in the process of operation, so the arrangement of lubricants must be determined according to the direction of the movement of the grinding part.
6. Superior drug resistance and corrosion resistance;
The lubricant of the solid self-lubricating bearing is made of the wear-resisting materials such as graphite, PTFE and molybdenum disulfide with special formula. It has stable molecular structure, and the metal matrix can be selected according to different metals with different drug resistance and corrosion resistance. Therefore, the solid self-lubricating bearing has superior drug resistance and corrosion resistance.
7. The bushing bearings cost is more competitive, compared with similar products, the service life is longer, the maintenance is less, the replacement cycle is long, the performance is good.

bronze-bushingsSolid bronze bearings are mounted on a matrix of colliers brass. A high performance solid lubricant with graphite or MoS2 solid lubricants. It breaks through the general bearing lubrication by oil film limitations. In the process of use, through the friction heat to make the solid lubrication and shaft friction, the formation of oil, powder co-lubrication excellent conditions, not only protect the shaft from wear, and make the solid lubrication characteristics eternal. Its hardness is higher than average copper sleeve one times, wear-resisting property is also one times. At present, the product has been used in metallurgical continuous casting machine, train support, steel rolling equipment, mining machinery, ships, gas turbines and other high temperature, high load, low speed heavy load and other occasions.

With the wear-resisting metal bronze bushing material as the matrix, the friction factor is reduced by adding various lubricating materials, and the self-lubrication is realized. This material structure combines the advantages of high load of metal, good impact resistance and low friction coefficient of nonmetal, and can be used in various working conditions. According to the distribution of solid lubricant is different, divided into according to certain proportion rule configuration set and evenly distributed in the working layer of dispersion of two kinds of solid lubricating bearing, Mosaic solid lubrication bearing is suitable for low speed and high load, and the dispersive solid lubricated bearing even under the condition of high speed in the micro, can keep a very low coefficient of friction.

Standard Dimensions For Lubrication Grooves, Design of lubrication hole and grooves

  • Length of lubrication groove should be 70-80% of bearing width, and all edges should be rounded
  • A lubrication hole should be located inside the lubrication groove
  • If lubricant is fed from the housing, a groove on the OD should be added to transport the lubricant to the inside of the bearing.

Types of self-lubricating bronze bearings groove: There are different types grooves or plugged graphite which should be used according to the type of lubricant and movement.*Grooves can be closed or open on one or both sides.

The so-called oilless bushing self-lubricating bronze bearings means that there is no need to add oil or less oil. The goal of our research is to ensure that the bronze bearing can still perform well under such conditions and extend its service life as much as possible. Self-lubricating bearing is the basic working principle of solid lubricant on the surface of the bearing in the early operational stage due to the friction of ask each other to form a transfer film and coat the to eventually form solid lubrication film on the grinding bushing parts to achieve the purpose of self lubrication, which partition the direct contact between the workpiece and good protection of grinding extend the service life of the bearing and artifacts.

CAPTION

1. Where possible, use standard specifications in the design;
2. Please pay attention to the presence of foreign bodies on the surface during assembly;
3. After using the sliding surface, the oil film formed by the solid lubricant causes the surface to have black or gray-black phenomenon, please do not scrub, use as usual;
4. Before bronze bushing bearing parts assembly, if the lubricating oil is applied to the grinding parts, the short running period can be reduced, which is conducive to the mechanical operation and operation;
5. When assembling, press in slowly, and do not knock, so as to avoid damage to the bearing and cause deformation;
6. When designing, different parts should choose appropriate material to improve the mechanical performance and prolong the service life of the bearing;
7. In high load and reciprocating motion, screw fixation is recommended.
8. Stainless steel or chrome plating is recommended for grinding shafts in fresh water, seawater and at sea.
