Trusted Oilless Bearings services

Bronze Plain Bearing – Maintenance – Free

Trusted handyman services

A bronze plain bearing is a type of mechanical component used to support rotating or sliding shafts within machinery. Unlike other types of bearings that require regular maintenance and lubrication, bronze plain bearings are designed to be maintenance-free. This means that they are engineered to operate efficiently and effectively without the need for constant upkeep.

These bushings are tailored to meet specific requirements outlined in custom drawings as well as industry standards such as VDI/BAK and NAAMS.

Bronze plain bearings function by incorporating lubricant within the sliding layer of the bearing. This lubricant can take the form of either a liquid (such as oil) or a solid (like graphite, MoS2, or lead), based on the specific demands of the application, including the operating temperature.

During the bearing’s operation, the lubricant is gradually released through pores present in the sliding layer, effectively lubricating the bearing surface.

To ensure optimal performance of your machinery, it’s essential to maintain your lubrication system in excellent condition. Additionally, periodic inspections of bearings should be conducted to identify and rectify leaks before they escalate into more significant issues. By regularly upkeeping the lubrication and bearing system, many common problems can be averted. Here’s a checklist to help you establish a lubrication system maintenance regimen that will keep your machinery running smoothly:

  • Regularly inspect the lubrication system for any signs of leaks or malfunctions.
  • Monitor lubricant levels and quality to ensure they meet the specified standards.
  • Clean the lubrication system components and replenish lubricants as needed.
  • Verify that all lubrication points are receiving adequate lubrication.
  • Replace any worn-out or damaged parts promptly.
  • Implement a schedule for lubrication system maintenance tasks and adhere to it consistently.
  • Train personnel responsible for maintenance on proper procedures and techniques.
  • Keep accurate records of maintenance activities, including lubricant changes and repairs.
  • Collaborate with manufacturers or experts if any complex issues arise.
  • By adhering to these guidelines and maintaining a proactive approach to lubrication system maintenance, you can uphold the efficiency and longevity of your machinery while avoiding preventable complications.

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.
