When selecting a lubricant, it is essential to consider the operating conditions, including temperature, speed, and potential exposure to contaminants. Additionally, it must be compatible with the bearing’s materials and other components that may come into contact with it.

A strong oil film protects the bearing from corrosion and other damage caused by exposure to contaminants. It can also serve as a thermal barrier and reduce heat transfer.

Cast bronze bushings are made from a solid or hollow bronze alloy bar stock that undergoes different processes to attain the final shape. This specific bronze alloy is created by continuous or centrifugal casting, which generates a metal with a fine grain structure and strong mechanical properties. The bronze alloy bar stock is then machined through a computer numerical control (CNC) lathe that cuts the cast bar, removes additional bar stock, and processes the finished bushing.

Lubricants highly resistant to corrosion can protect the bearing and its part surfaces from moisture damage. This will enable the bearing to operate correctly and last longer.

Good thermal conductivity will enable the lubricant to transfer heat away from the bearing and dissipate it into the environment. This helps maintain the temperature within safe limits, lowering the likelihood of overheating-related damage.

A lubricant with high thermal stability will withstand the bearing’s high temperatures without degrading or losing effectiveness. This is essential for components in high-temperature applications, such as engines and other machinery.

One thing to consider, though, is that cast bronze bushings are generally more expensive than others since the whole process of making them can be slow. They also require additional lubrication.

A lubricant that effectively reduces friction between the surfaces of a bearing will allow the parts to move smoothly and easily. Also, low abrasion properties can protect surfaces by minimizing the amount of friction caused by every movement.

Ball bearings are mechanical components in machines and equipment that enable the smooth and low-friction rotation of moving parts. When a bearing operates, the rolling elements and rings come into contact, which causes friction and heat. Lubrication reduces this friction by forming a film between surfaces, preventing metal-on-metal contact and overheating.

Oil impregnatedmeaning

Grease is commonly used in lower-speed and lower-temperature applications. It is typically a combination of oil and a thickening agent for lubrication and keeping the lubricant in place. Grease lubricants are easy to apply and handle without constant monitoring. They can also separate contaminants and seal out dust and dirt.

Bronze bushings are common nowadays as they can effectively resist shock, impact, wear, and corrosion. These bushings can also be used at high temperatures without getting damaged. Bronze, as a material, can be easily machined, brazed, and soldered, allowing it to be moulded into high-quality bushings. To date, two types of bronze bushings can be used in the industry. These two types are cast bronze bushings and oil impregnated bronze bushings.

Oil Impregnated BronzePlate

A lubricant with stable viscosity will exhibit consistent resistance to flow over a broad range of temperatures, pressures, and shear rates. This characteristic ensures that the lubricant will provide the required film thickness and performance each time.

All the processes involved in making cast bronze bushings do not involve any powder, which makes them attain a finer grain structure and greater structural strength. Cast bronze bushings are known to be much stronger, more durable, and more resistant against compressive forces. These features make cast bronze bushings recommended for applications with heavy loads.

Oil impregnated BronzeWasher

There are two types of lubricants for lubricating ball bearings: oil and grease — each type has unique properties and advantages. Consequently, the most suitable lubricant for an application will depend on the operating conditions and bearing material.

As for the disadvantages, oil impregnated bronze bushings are not great for applications that might react to their impregnated oil. These bushings have also limitations with regards to their mechanical strength.

Oil impregnated bronze bushings, alternatively, are made by feeding the bronze powder into a die set that is set according to the bushing size. Afterward, the powder particles are pressed tightly together. The bonded powder particles are then placed in a furnace, with its temperature set high enough to effectively join the particles without melting them. The sintering process of metal particles helps them decrease porosity. As for oil impregnated bronze bushings, the final porosity is set at around 25%.

Oil Impregnated BronzeStock

One type of bearing that is used by a wide variety of industries today is known as a bushing. Bushings are maximised to reduce friction and wear between two surfaces that slide against each other. They are found inside a given hole and often used as a casing for a shaft, pin, or hinge. Machines and equipment that have rotating or sliding shafts often need bushings to improve overall efficiency and reduce vibration, noise, and wear.

Lubrication is essential for maintaining the proper operation and longevity of ball bearings. It also ensures the smooth and efficient operation of the equipment in which they are used.

A ball-bearing lubricant must possess the following characteristics to provide adequate lubrication and bearing protection:

High-quality bearings are essential for the proper functioning of equipment and machinery. Without them, even the best lubrication would not be able to maintain the performance and longevity of the component. At SPB-USA, we can provide precision bearings in various sizes and load capacities to suit different applications.

Once the final porosity is maintained, the bronze bushings are then pressed through a set of tools that will provide them the required tolerances. They are ultimately vacuum impregnated that forces oil to their interconnected porosity. Given these processes, oil impregnated bronze bushings can be advantageous due to their lower scrap loss. Manufacturing them at high volumes is also more feasible compared to cast bronze bushings. Also, these bronze bushings do not require any more additional lubrication.

Oil is a lubricant typically used in applications involving high speeds, loads, and temperatures. It delivers better heat dissipation and protection from wear and corrosion than grease. It also has a higher load-bearing capacity and oxidation resistance. Furthermore, oil can reach tight spaces that are difficult to lubricate with grease.
