Types of Self Lubricating Bronze Bushing Material & Specification:
Graphite Self Lubricating Bronze Bushing
Graphite Self-lubricating bronze bushing lubrication principle is in the process of sliding friction between shaft and bearing, part of the graphite particles transferred to the friction surface of the shaft and bearing, forming a more stable solid lubrication diaphragm to prevent direct adhesion wear of the shaft and bearing.
Graphite Plugged Bronze Bushings
This rational combination combines the respective performance advantages of metal alloys and non-metallic wear-reducing materials to complement each other, i.e. with the high load-bearing capacity of metals and the lubricating properties of wear-reducing materials. So It is especially suitable for heavy load, low speed, reciprocating or oscillating, and other difficult to lubricate and form oil film occasions, and is not afraid of water and other acid corrosion and scouring.

Benefit Of Self Lubricating Bronze Bushing
No need for oil supply units, oil filling holes, oil tank machining, etc., which significantly reduces manufacturing costs
The reduction in movement costs significantly reduces the amount of lubricant used and the maintenance costs of the equipment, in addition to eliminating the risks caused by insufficient oil supply.
Reduced design time Oil-free allows for significant simplification of design, structure, etc., reducing costs and saving design time
The use of self-lubricating bearings also improves mechanical properties, extends service life, and increases reliability
Recycling and environmental protection of lubricating oils without the need for waste oil recycling and disposal contribute to environmental protection.
Self-lubricating Bushes VS Oil Impregnated Bronze Bushing
Oil Impregnated Bronze Bushing is a combination of metal powder, there are 10 ~ 40% of the structure of the gap; Graphite plugged bronze bushing matrix is centrifugal casting and made; matrix density is relatively high, higher strength, the service life is longer than Oil Impregnated Bronze Bushing.
Sinter Bronze Bushing
Oil Impregnated Bronze Bushing is a sintered body made of metal powder as the main raw material by the powder metallurgy method. Using the porous nature of the sintered body, it is impregnated with 10% to 40% (volume fraction) of lubricating oil and is used in a self-oiled state. When the bearing temperature rises during operation, the coefficient of expansion of the oil is greater than that of the metal, so it automatically enters the sliding surface to lubricate the bearing. Oiled bearings can be used for a longer period, and are often used in situations where refueling is not convenient.
Graphite Bronze Bushing
Graphite Bronze Bushing is a kind of both metal bearing characteristics and self-lubricating bearing characteristics of the novel lubrication bearing, by the metal substrate to bear the load, the special formula of solid lubricating materials to play a lubricating role. It has a high bearing capacity, impact resistance, high-temperature resistance, self-lubricating ability, and other characteristics. especially for heavy load, low speed, reciprocating or oscillating, and other difficult to lubricate and form oil film occasions, but also not afraid of water and other acid corrosion and erosion.

Why Use self lubricating bronze bushing?
To ensure the stability and reliability of bronze bearings, most bearings lubricate with oil:
- Reduce internal friction and wear and to prevent combustion:
- Extend the fatigue life of the bearing
- Discharge frictional heat or heat transferred from the outside;
- Provide some vibration absorption capacity from the oil film.
Protecting the Environment & Reliable
However, one of the biggest disadvantages of adding lubricating oil is the need for good sealing properties, otherwise, leakage will occur, and certain equipment with special requirements does not allow lubricating oil leakage, so people use graphite instead of lubricating oil. self-lubrication bronze bushing was invented, which not only has the advantage of containing lubricating oil in the bearing but also eliminates the environmental pollution caused by leakage.
