Why Use Graphite As A Solid Lubricant？
Graphite plugs provide self-lubrication. It has some unusual properties that make it an excellent solid lubricant.
- Due to the good friction reduction performance of graphite, a wide range of operating temperatures, and physical and chemical properties do not change when high-temperature molding. It has become the most commonly used solid lubricant for the self-lubricating bronze bushing.
- Graphite is chemically stable, insoluble in drugs and solvents, corrosion resistant, high-temperature resistant, a good conductor of heat and electricity, non-toxic, and inexpensive.
- When graphite is embedded in a metal substrate, it will form a more stable lubricating film on the relative sliding surface when moving with each other. To achieve the effect of lubrication and friction reduction.
Graphite bronze bearings (JDB ) is a novel lubricating bearing that combines the characteristics of metal bearing and self-lubricating bearing. It has the characteristics of high bearing capacity, impact resistance, high-temperature resistance, and strong self-lubricating ability. At present, the products have been widely used in metallurgical continuous casting machines, sintering machines, steel rolling equipment, mining machinery, ships, steam turbines, water turbines, injection molding machines, and equipment production lines.

Graphite Impregnated Bronze Bushings – Choice Of Substrate Material
The following are common base materials for Graphite Impregnated Bronze Bushings
High Force Brass As The Base – Graphite Impregnated Bearing
The hardness and wear resistance of high-force brass is twice as high as that of general brass bushings. At present, it has been widely used in cure gold continuous casting machines, train support, steel rolling equipment, mining machinery, ships, gas turbines, and other high temperature, high load, low-speed heavy load, and other occasions use.
Tin Bronze As Substrate
Bronze bearing with graphite is a solid lubrication product with 6-6 bronze. Because the density of 6-6-3 bronze is higher than high force brass, in high temperature and low load occasions, embodies very wear-resistant and has been used in the fireplace door, oven raceway, rubber machinery, light industry machinery, machine tool industry, and other low load, high temperature, medium speed occasions.
Steel And Copper Inlay As The Base
Steel plate inlay bearing is a solid lubricant product embedded with solid lubricant after sintering tin bronze powder as a whole in the base body of the steel sleeve, which can save cost and improve compressive strength in addition to the function of tin bronze as the base body. Its section can be installed and used with the substrate by welding, so it is suitable for fields that cannot be refueled, such as metallurgical machinery, construction machinery, and oil transfer machinery.
Graphite Embedded Steel bearing
Graphite embedded Steel bearing is a strengthened product and has a very high-pressure resistance, inlay graphite work when the discharge of lubricating particles, so that the shaft and the sleeve between a layer of the diaphragm, played than a single body of oil lubrication anti-seize advantages. In lifting machinery, support parts are particularly adapted. Example: rolled earth machine support, crane support, etc., but should not be used in water or acid and alkali occasions.
Cast Iron Inlaid Tin Bronze Substrate
Cast iron inlay bearing is a new product with HT250 as the base material embedded with solid lubricant, which is a typical material-saving product. If the pressure <14.5N/mm2 or mechanical performance requirements are not very high occasions, can do tin bronze as a substitute for the substrate. It can greatly reduce the cost and meet the requirements of use. For example mold guide pillars, injection molding machine mold frames, and other fields can be used.
Reasons For Selecting Graphite Impregnated Bronze Bushings
1. Total Self-Lubricating:
No oil or grease is required: The self-lubricating features allow bearings to be used where oiling is difficult, expensive to implement, and where grease/oil cannot be used. Excellent lubrication is achieved even under high loads at low speeds.
2. Excellent Wear Resistance:
Excellent wear resistance is achieved under severe working conditions, such as heavy load, low velocity, reciprocating, oscillating, and intermittent motions where the formation of oil film is difficult. Wear resistance: Solid lubricating materials generally have very low shear strength and strong adsorption to the surface of metal substrates. At the beginning of the bearing operation, the solid lubricant undergoes sheer slip and is continuously adsorbed on the exposed metal surface, so that the entire friction interface quickly forms a layer-transfer lubricating film. The formation of the solid lubricating film avoids the direct friction between metal and metal. reduce wear.
3. Low Coefficient of Friction: 0.04 to 0.2 typical:
Self-lubrication with specially embedded solid lubricants reduces friction. The solid lubricating block (or stick) embedded in the substrate generates heat when it is rubbed with the dual material, and the solid lubricant is extruded by thermal expansion, forming a lubricating film, and forming a transfer film on the surface of the dual material to achieve lubrication. The friction occurs inside the lubricant so that it can show good friction characteristics – a low coefficient of friction. Also, the coefficient of friction decreases with increasing load and speed.
4. Wide Operating Temperature Ranges: -415° ° to 1,100° °F
Superior performance is exhibited under high and low-temperature conditions. solid lubricating materials can work in a wide temperature range. The upper limit of use temperature is above 1000℃, and the minimum use temperature is below -150℃. No solid lubricating material has such a wide working range, and the actual circumferential lubricating material only needs to be adapted to a specific temperature range. Corrosion resistance and radiation resistance: Solid inlaid self-lubricating bearings and counterparts can work in acid, broken, salt, mist, water, seawater, and other corrosive liquids or gases. Solid lubricated bearings working in a corrosive medium environment can maintain stable performance and ensure their good lubricating performance within the specified service period. Within the specified period of use, it can withstand a certain amount of radioactive radiation. Its physical and mechanical properties and tribological properties should remain stable.
5. Corrosion and Chemical Resistance:
Performance is not affected by water and caustic chemicals.
6. Designed to Exceed Your Requirements:
High-precision products with close tolerances.
7. Cost Competitive:
Maintenance, replacement, and end-item downtime cost are reduced due to the exceptional service life compared to similar self-lubricating products.
