Solid Lubrication Bearings Bushing Products Features

1. No need to oil installations, the lling hole processing tank The cost of oil installations, processing fees, assembly fees, the extra cost and time savings can signicantly reduce manufacturing costs.
2. Lower operating costs Substantially reduce the use of lubricants and equipment maintenance costs, while also eliminating the risk caused due to insucient oil supply.
3. The shortening of design time Non-oil can make the design, structure, and greatly simplify and reduce costs, save design time and to obtain significant results, in addition, the use of self-lubricating bearings can also improve the mechanical properties and extend the service life and higher reliability.
4. Lubricating oil recycling and environmental protection No need to waste oil recycling, are environmentally friendly. the self-lubricating bearing parts of the machinery industry, the use of certain generalized. In order to make the mechanical drive is operating normally, a lot of effort. The bearing area is divided into Rolling and plain bearings. Sliding bearings in high-load movement, foreign substances, temperature, fuel, maintenance, imperfect circumstances, can cause galling. Like sliding bearings can not be used under harsh conditions, the solid inlaid metal self-lubricating bearings, wear resistance, resistance to galling, to play the bearings of the due performance, the role of mechanical performance and maintenance-free.

The Advantages of the Solid-Lubricant-Inlaid Bearings

1. Properly and simply designed, widely used;
Oil offering system is an energy waste and time waste set in mechanical design. There is no needs for considering the oil-putting set in design when using the solid lubricant bushing so it can save the oil-putting equipment and at the same time it also design the solid-lubricant-inlaid bushing into alt kinds of shapes in order to meet various needs in special places. Using solid-lubricant. inlaid bushing can reduce the costs of the machinery mending and the oiI in wide range.
2. Being used without oil;
Because of the linear coecient expansion of the solid lubricant is bigger than that of the metal basement, when the solid-lubricant-inlaid bushing starts to operate, the oil lm can transfer to the corresponding friction set to make out self-lubricant. So the solid-lubricant-inlaid bushing can be used in places where the oil or grease cannot be added. It can make out the self-lubricant function even though under high load conditions．
3. Low cost for usage;
Traditional mechanical design asks for frequently aiding oil and checking if the oil watch and the oering set are through in certain period. Because adding oil at regular intervals causes the pollution to the machine itself and the nearby surroundings and increase the maintenance cost. And when the self-lubricant is made out, it can not only make the surroundings clean but also decrease the cost of using the Iubricant．
4. The superior functions can be brought into play under high load and low rotati ng speed．
The solid-lubricant-inlaid bushing is based on the high intensity brass that is centrifuge cast. And then make out the loading function. Use special graphite that has good self-lubricant properties as lubricant to make out the self-lubricant so that the bushing has included all of their advantages. It can still bring the superior properties into play even under high load and low rotating speed．
5. The wear resistance can be brought into play even ln places the oil film form into difficulties because of the reciprocating and rocking movement, starting and stopping;
The arrangement principle of the lubricant of the solid-lubricant-inlaid bushing is to ensure that all the parts of the corresponding friction sets have the lubricant function in the operating procession. So the arrangement place 0f the lubricant should be depended upon the operating direction of the corresponding friction sets．
6. Superior chemical resistance and corrosion resistance;
The lubricant of the solid-lubricant. inlaid bushing is made of special graphite and PTFE. It has steady molecule structures. The metal basement can be chosen according to the dierent chemicaI resistance and corrosion resistance of the metal appliance. So the solid-lubricant-inlaid bushing has the superior chemical resistance and corrosion resistance．
7. The products is more competitive, comparing to the similar kinds of products, this kind of products has longer working life and need seldom maintenance. It has longer replacement ci rcle and good properties．
