When it comes to Sankyo bush replacement, using plugged graphite is often a preferred choice due to its unique properties and advantages. Graphite, a natural mineral, is renowned for its excellent self-lubricating capabilities, high thermal conductivity, and low coefficient of friction. These properties make it a suitable material for various bush applications, especially in environments where wear and tear are significant concerns.
The "plugged" aspect refers to the process of inserting graphite into metal bushings, usually by press-fitting or machining grooves and filling them with graphite powder. This method provides a wear-resistant and lubricating surface, extending the bush's service life and reducing the need for frequent maintenance.
When selecting plugged graphite bushings for Sankyo bush replacement, it's essential to ensure the quality and fitment are precise. The graphite should be of high purity and density to ensure optimal performance. Additionally, the bushings should be designed to fit the specific application, taking into account factors like load, speed, and operating conditions.
In summary, using plugged graphite for Sankyo bush replacement offers several advantages, including improved wear resistance, self-lubrication, and extended service life. However, it's crucial to select the right material and ensure proper installation to maximize these benefits.

NEXT-LEVEL PERFORMANCE
Consistent. Proven. Self-lubricating Quality.
A wide range of self-lubricating bearing assemblies is used for your application.
Solid bearings are on the high strength of the brass substrate. Mosaic of
graphite or a high-performance solid lubrication Mos2 solid
lubricant products. It broke through the general bearing on the
limitations of the oil film lubrication. In the use process,
through the friction heat make solid lubrication and shaft
friction, the excellent conditions of forming, powder, and oil
lubrication, both to protect shaft wear and tear, and the solid
lubrication characteristics of eternity. It is twice as tall as a
general copper sleeve, wear-resisting performance is twice as high.
Now the product has been used in a metallurgical continuous casting
machine, train stents, steel rolling equipment, mining machinery,
shipping, steam turbine and other high temperature, high load,
low-speed heavy, etc.

1, design flexible, simple and convenient, use range is extensive; Fuel supply system in the mechanical design is a work, time-consuming device, using solid self-lubricating 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 the 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 to add D oil and not oil or grease, even in the case of low speed and high load, also can have good lubrication effect.
3, use cost is lowThe 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, high load, low speed, can produce 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, reciprocating motion, swing motion, start-stop frequent oil film forming difficult place, can play the superior wear resistance; The arrangement principle of solid self-lubricating bearing lubricant is a guarantee for grinding parts in the process of running parts have lubricant effect, therefore arrange lubricant must be according to the movement direction of the grinding parts to determine the arrangement of lubricant.
6, superior drug resistance and corrosion resistance;Solid self-lubricating bearing lubricant is using a special formula of graphite, PTFE, molybdenum disulfide, such as wear-resistant materials, it has a stable molecular structure, the metal substrate can be according to the different metals have different 9 drug resistance and corrosion resistance to choose, so solid self-lubricating bearings have the superior drug resistance and resistance to alone.
7, The product cost more competitive, compared with similar products, the service life is longer, need little maintenance, the replacement replacement cycle is long, good performance.
In today's modern design self-lubricating bearing material is undergoing a lot of demand. Even in an extremely serious work environment and the maximum load conditions also requires no maintenance. With the constant improvement of the cost requirements, the enterprise also to the reliability of the equipment and factory operation requirement is higher and higher. Metal self-lubricating bearing can meet the free maintenance and in use for a long time under the condition of self-lubrication, which makes it possible to design a reliable long-term self-lubricating system. Metal type self-lubricating bearing materials can be widely used in high load under the condition of low-speed rotation, swing and the straight line reciprocating movement, but also for traditional lubrication cannot reach or are banned from using occasions, or in special conditions such as dust, impact load or irradiation conditions such as the need for the use of long-term and stable.
1.no oil supply device, the cost of oil injection hole, oil
processing, and oil supply device, processing and assembling
charges, and other extra cost and time savings, can significantly
reduce manufacturing costs.
2. lower running cost of sharply lower oil demand and equipment
maintenance fee, also be exempted from the risk due to inadequate
oil supply.
3.design time shortened without oil can make the design, structure
greatly simplified, reduce costs, save design time, in addition,
use self-lubricating bearings can improve the mechanical
properties, extend the service life and improve reliability for the
significant effect, etc.
4.lubricating oil recycling and environmental protection without
waste oil recycling are conducive to environmental protection.
since the bearing parts for the machinery industry, the use of a
broadly. In order to make the mechanical drive running normally,
under a lot of kung fu. Differentiate bearing for rolling bearing
and sliding bearing. The general way of sliding bearing in high
load movement, foreign bodies, interfuse, temperature conditions,
oil supply and imperfect maintenance cases, can lead to hair. Like
this usually can't use harsh conditions of sliding bearing, solid
inlay type of self-lubricating bearing metal wear resistance,
resistance to hair, play the performance of the bearing, mechanical
high-performance and free maintenance.
1.where possible, as far as possible when the design adopts the standard specifications;2. The assembly time please note surface had a foreign body.
3. after use of the sliding surface, the surface is caused by the formation of the solid lubricant oil film in the black or colored phenomenon, please don't scrub, used as usual;
4.before assembly, if to grease in a ring, can be shorter running-in period, for mechanical operation, operation;
5.assembly should be pushed slowly when it is strictly prohibited, so as not to damage the bearing and deformation caused by; A different part of the
6.when the design should choose the appropriate material, in order to improve the mechanical properties, extend the service life of bearing;
7.in high load-bearing, reciprocating motion, recommend the use of screw fixation;
