Graphite Impregnated Bronze Bushings | Available Online

Choose from our many standard sleeves and flanged Graphite Impregnated Bronze Bushings, in both metric and imperial sizes, or let us produce a custom part to your exact specifications.

Graphite Impregnated Bronze Bushings are used principally to guide or control some form of linear motion, often under considerable load. The range of possible applications is very broad: dies, molds, fixtures, special machines, and heavy equipment of all types. Our components have an extremely long life, often exceeding that of the tool or machine in which they are installed.

Graphite Filled Bronze Bushes | Self-Lubricating

Graphite Impregnated Bronze Bushings are a complete line of Self-Lubricating Bushings that excel whenever standard lubrication is impractical, including heavy load, high-temperature applications. They are manufactured from a variety of Bronze Alloys, including C95400 Aluminum Bronze, C93200 Bearing Bronze, and C86300 Manganese Bronze

Self-Lubricating Components

Many of our components are self-lubricating. Self-lubricating components are initially more expensive than conventional components; however, they possess the advantage of having permanent lubrication built-in. No additional lubrication will be required, ever. In terms of total life cycle cost (i.e., when the cost of performing periodic greasing is considered), self-lubricating components are always less expensive than conventional components – often considerably so since there is the risk of the lubrication not being applied.

Graphite – solid lubricant

Graphite plugs provide self-lubrication. Graphite has some unusual properties that make it an excellent lubricant. Chemically, it is one of three common allotropic forms of carbon (amorphous carbon and diamond being the other two). In contrast to diamond, which has a very dense and strong three-dimensional crystal structure, graphite has a two-dimensional crystal structure – strong in two dimensions but weak in the third.
Graphite becomes distributed over the wear surface and acts as a solid lubricant. It will stay there a long time due to graphite’s superior stability.

We supply a large portfolio of lubrication-free GRAPHITE IMPREGNATED BRONZE BUSHINGS

We’re here to help

You can rely on our high quality for all special graphite impregnated bronze bushings parts. They are made of the same materials as our standard parts.

  • Bronze graphite impregnated bushings bearing (for small and medium sized parts), self-lubricating

  • We also manufacture in your special graphite impregnated bushings bearing sizes, plate and materials. Please contact us. The technical department will be pleased to help you.

The Advantages Of The Graphite-Impregnated Bushing

  • Properly and simply designed, widely used;

  • Being used without oil; Low cost for usage;

  • The superior functions can be brought into play under high load and low rotati ng speed.

  • 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;

  • Superior chemical resistance and corrosion resistance;

  • The products is more competitive, comparing to the similar kinds of products, comparing to the similar products. Such products feature longer working life and good performance but rarely require maintenance.

Where Are Graphite Impregnated Bronze Bushings Used?

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. scour. 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.

Benefit Of impregnated bronze bushings 

Because graphite plugged bearings self-lubricate, money is saved on maintenance and replacement—both in materials and in labor costs. Additionally, less downtime is needed to add more lubricant or perform other everyday maintenance tasks. Graphite plugged bushings have better wear resistance than other types of bearings. This is because when graphite plugged bushings are in use, there is very minimal friction thanks to the lubricant film they produce. Friction is what wears parts down and causes them to need eventual replacement, so limiting this is the key to durability.

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.
