Oilless Guide Bars

The oilless guide bars are made of metal base material and solid lubricant compound, it uses the complementary performance of two materials to achieve oil-free self-lubrication under heavy load, high temperature, not easy to form lubricating oil film or oil film failure, to slow down the wear and improve the life of the purpose. oilless guide bars can be divided into powder metallurgy integral sintered type and inlay type according to the manufacturing method. The inlay type self-lubricating bearing consists of a metal substrate and a solid lubricant embedded in its hole. During the grinding process, most of the load is borne by the metal substrate. By friction, the solid lubricant in the hole is transferred to the friction surface, which forms a well-lubricated, firmly attached, evenly covered solid transfer film on the friction surface, thus playing a role in reducing the effect of friction

Solid inlay self-lubricating bearing is in the ordinary sliding bearing (sleeve), shaft tile and slider, guide bars, and other parts of the friction surface of the relative mechanical movement, through a reasonable cloth hole, slot, and in its hole slot embedded with a certain shape and strength of the solid lubricant and made products. The embedded lubricant includes graphite, sulfide (molybdenum disulfide, tungsten disulfide, etc.), calcium fluoride, synthetic resin, polytetrafluoroethylene, etc.

The thermal expansion coefficient of the embedded solid lubricant is greater than the expansion coefficient of the embedded substrate, and the type of embedded solid lubricant is selected according to the working condition.

Guide bars are an essential component in injection molding machines, playing a crucial role in ensuring the proper operation of the machine and the production of high-quality plastic parts. These bars are responsible for guiding and supporting the moving parts of the injection molding machine, such as the mold, platen, and injection unit. Here’s a guide on guide bars in injection molding machines:

Function of Guide Bars:

1. Guide bars are precision-engineered components designed to provide stability and alignment for the moving parts of an injection molding machine.
2. They help maintain the proper distance and alignment between the mold halves (the stationary and moving plates) during the molding process.
3. Guide bars ensure that the mold closes and opens smoothly, preventing misalignment and reducing wear and tear on machine components.

The oilless guide bar combines the wear resistance and high load-bearing property of copper alloy and the self-lubricating environmental performance of solid lubricant and can be machined with various oil grooves and oil holes on the friction surface. After inlaying solid lubricant, it can adapt to different environmental conditions. So that it does not need oiling and maintenance in the process of use.
It is widely used in high load, intermittent or reciprocating motion, such as steam locomotive production line, home appliances, automobile, and other stamping dies, large metal extrusion equipment, hydraulic turbine, etc. bronzeoilless.com also provides you with an L-shaped oilless slide plate, V type wear plate, bronze slide plate, cam plate…

The benefits of using oilless guide bars include reduced maintenance, improved performance, and reduced environmental impact. Because oilless slide plates do not require lubrication, they are easier to maintain and reduce the need for frequent oiling. This saves time and reduces costs associated with regular maintenance. In addition, the self-lubrication provided by the coatings on oilless slide plates improves their performance by reducing friction and heat generated during operation. This results in smoother and more efficient movement, reducing wear and tear on the bearing and improving overall system efficiency.

Oilless guide bars also have environmental benefits. Because they do not require oil or grease, there is no risk of oil spills or leaks, which can harm the environment. Additionally, oilless slide plates do not emit any oil vapor, reducing air pollution and improving air quality.
