Bronze Plain Bearing Maintenance

Bronze Plain Bearings are important mechanical components that help in maintaining the linear and rotational movements of a machine and it is important they are maintained properly to ensure long operational life.

Plain Bearings play a significant role in the free and unrestricted movement of mechanical parts or components, from your car wheels to your skateboards as well as many other things too. Bearings bear the weight of the load and make things move without any or with much less friction. In a world without bearings, mechanically moving parts will malfunction and stick, preventing smooth operation. Plain Bronze Bearing life can be affected based on the type of bearing, the load they are asked to carry, and the maintenance schedule. Properly maintained, bearing life can be extended and downtime can be reduced.

Bearing Maintenance-free | Help Ensure A Longer Lifespan

  • Handle with care

Bearings are delicate enough to get damaged quickly. As such, it is very important that they are stored horizontally in a clean and dry environment with their packaging intact. Do not expose them to any airborne contaminants, as even a tiny speck of dirt can cause premature failure. Never hammer or pound them, or apply a direct force on it or its outer ring, which can cause damage to the rolling elements, resulting in misalignment. The most important thing to remember is to never remove bearings from their packaging until ready for use.

  • Check the bearing housing and shaft

Whenever a bearing is used for mounting, it is crucial that the housing and shaft are inspected for any sort of physical condition or damage. Always use a soft cloth to wipe the surfaces clean and make sure any nicks and burrs are removed.

  • Mount the bearings correctly

The method used to mount the bearings depends on the type of bearing. For example, bearings with cylindrical bores are generally mounted through a press-fit method. Bearings with tapered bores can be mounted directly on tapered or cylindrical shafts with the use of tapered sleeves. However, pressure should be applied only with a press fit because without it the raceways can become damaged.

  • Avoid preheating or overheating

The maximum heating allowed on the bearings depends on the heat treatment of the material. If they are heated above the permitted limit, they can permanently deform or soften the bearing steel, lowering load carrying capacity and resulting in a failure. Always heat the bearings using induction heaters, and never with an open flame.

  • Always use the proper tools

Specialized tools like bearing pullers, bearing fitting tool kits, oil injector kits, hydraulic nuts, or induction heaters should be used in the mounting and dismounting processes. These tools ensure the smooth process of mounting or dismounting, in order to minimize the risk of damage.

  • Avoid corrosion

It is crucial that you should not expose bearings to the presence of water for a long time, as it will lead to rust and corrosion. It will also cause the premature failure of the bearings, which can affect the performance and productivity of the machine. As a result, it will increase your operating costs. Also, make sure to wear gloves when handling bearings. Perspiration can also lead to rust and corrosion.

  • Proper lubrication

If you want to have a prolonged life of your bearings, it is crucial that they should be properly lubricated. The correct lubricant depends on the environmental conditions, temperature, speed, and load. In this case, it is advisable that you should follow your manufacturer’s recommendations.

What Is A Solid lubrication Bronze Plain Bearing

Solid lubrication plain bearing is based on metal material, using graphite as a solid lubricant, made by a special process, is a solid lubricant has uniform voids, and can contain a certain amount of lubricant. When working under oil-free conditions, the combination of lubricating oil and solid lubricant is gradually distributed to the friction surface through friction heat to make it achieve the efficiency of a small friction coefficient and good wear resistance. All the Solid lubrication plain bearings are processed by numerical control machine tools to ensure the stability of product quality. Bronze plain bearings are widely used in metallurgical machinery and equipment, steel wheel rollers and ship gas turbines, etc.

Self-lubricating Bronze Plain Bearings

Firstly, when using bronze plain bearings, what should you bear in mind? For your specific project you would like to know why bronze plain bearings are the better decision. For instance, using bronze plain bearings generally requires the use of special grooves, as well as the use of grease and oil for maintenance, which is expensive. Dry running poses a danger to bronze plain bearings, which happens when the greasing lubricating system fails. Curious about the consequences of dry running? In addition, many of the advantages that bronze plain bearings offer will offset these drawbacks. Learn more about the benefits of self-lubricating bronze plain bearings. Do not hesitate to contact us.
Secondly, self-lubricating materials, initiate by being pressed into a cylindrical, flanged, bar stock, or tube.
Thirdly, the sintered bronze with solid lubricants has a detailed self-lubrication process. The bronze bearing with solid lubricant is a high-quality material for heavy loaded parts.

Lubrication System Maintenance

To keep your machines operating at their peak it is important to keep your lubrication system in tip-top shape too. Also, inspections bearings should be performed periodically to detect leaks that can be repaired before they become serious problems. With routine lubrication-bearing system maintenance, many common problems can be avoided. Here is a checklist to help you implement a lubrication system maintenance program that will keep your machines operating smoothly.

Advantages Of Oilless bronze Plain Bearings & Wear Plates

  • Long life cycle – consistent performance and the possibility of maintenance-free operation can extend the life of a bearing by as much as three times.

  • Easy installation

  • Costing savings – time and money saved by eliminating the need to maintain the bearing.

  • Increased shaft tolerances possible

  • Environmental constraints – The environment in which the bearing operates also affects its maintenance-free capability. For example, when operating in areas with high particle content or excessive grease and dirt, the solid lubricant used can reduce the penetration of dust, grit, and liquids, preventing premature failure.

Self-Lubricated Technology

Our portfolio offers maintenance-free oilless bronze bushings for high loads and a long life-time according to custom drawings and common standards (VDI/BAK, NAAMS).

Bronze Plain Bearing work by having lubricant impregnated within the sliding layer of the bearing. This lubricant can either be liquid (oil) or solid (graphite, MoS2, lead) based on the requirements of the application (such as operating temperature).

As the bearing operates, the lubricant is released through pores in the sliding layer, lubricating the bearing surface.
