Detailed Maintenance and Lubrication Guidelines for Optimal Performance

Ensuring the longevity and smooth operation of sliding elements, such as bearings with solid lubricants, requires diligent maintenance and proper lubrication practices. The following guidelines outline the necessary steps before installation, during operation, and during transport and storage to ensure that your sliding elements perform optimally and maintain their reliability over time.

Preparation Before Installation

1. Clean Mounting Surfaces:

   • Thorough Cleaning: Before inserting any sliding elements, it is critical to ensure that all mounting surfaces within the housing are thoroughly clean. Any dirt, dust, or debris can interfere with the proper fit of the bearing or plate and cause premature wear or misalignment during operation.
   • Use Appropriate Cleaning Agents: If needed, use a mild solvent or degreaser to clean the surfaces, but ensure they are completely dry before installation.

2. Oil Film Application:

   • Lubricate the Back Surface: Apply a light oil film to the back surface of the bearing or sliding element prior to installation. This helps to facilitate the mounting process and reduces friction during the initial operation. The oil film acts as a temporary lubricant and ensures a smoother insertion into the housing.
   • Avoid Over-Lubricating: A thin, even layer is sufficient. Excessive lubrication can attract dust and contaminants, which may negatively affect performance.

Lubrication Before Mounting

1. Axle Lubrication:

   • Greasy Film Application: Before mounting the axle, apply a light greasy film to the sliding surfaces of the bearing. This grease serves multiple purposes:
     • Prevents Initial Wear: The lubrication minimizes the risk of wear on the sliding surfaces during the first moments of operation.
     • Activates Solid Lubricants: This film helps activate the embedded solid lubricant (such as graphite) in the bearing, ensuring it starts working effectively as soon as the components begin to move.

2. Ensure Even Lubricant Distribution:

   • When applying grease, ensure it is evenly distributed across all sliding surfaces to avoid any dry spots that might increase friction and wear. For large or complex components, use a brush or a clean applicator to spread the grease evenly.

Regular Inspection and Maintenance

1. Inspection Interval:

   • Routine Wear Checks: Regular inspection is key to identifying early signs of wear or degradation before they lead to failure. For most applications, it is advisable to inspect the components every 6 months to 2 years, depending on the load conditions and frequency of use.
   • Visual Inspections: Look for signs of excessive wear, scoring, or the breakdown of the lubricant. If wear is visible, further investigation may be necessary to determine whether the components need replacement or maintenance.

2. Re-greasing Procedure:

   • Single Re-Greasing After Disassembly: When disassembling components for maintenance, apply a single re-greasing after cleaning and before reassembly. However, take care to ensure that the sintered sliding film of solid lubricant is not removed during this process, as it plays a vital role in reducing friction and ensuring long-lasting performance.
   • Proper Lubricant Selection: Ensure that the lubricant used for re-greasing is compatible with the solid lubricant embedded in the bearing. Using the wrong lubricant can impair the solid lubricant’s effectiveness and lead to premature wear.

Maintenance-Free Operation

1. Continuous Lubrication Not Required:

   • Self-Lubricating Technology: Bearings with embedded solid lubricants, such as graphite-filled bronze bearings, are designed for maintenance-free operation under normal conditions. These bearings do not require continuous lubrication, provided that the application follows the prescribed operating conditions (load, speed, and environment).
   • Initial Lubrication Suffices: Once lubricated and installed, these components should perform effectively without the need for regular lubrication, reducing downtime and maintenance costs.

2. Monitoring Performance:

   • While continuous lubrication is not required, it is important to monitor the system’s performance and condition periodically, especially under harsh operating conditions or extreme loads. If you notice an increase in noise, friction, or temperature, it may indicate that the solid lubricant is depleting and re-greasing or replacement may be necessary.

Transport and Storage Guidelines

Proper transport and storage of sliding elements are crucial to avoid damage and ensure the components remain in optimal condition until they are ready for installation.

1. Storage Conditions:

   • Dust-Free and Dry Environment: Store bearings and wear plates in a clean, dry environment to prevent contamination by dust, dirt, or moisture. Exposure to moisture can cause corrosion, while dust can interfere with the lubrication system and affect performance.
   • Temperature Control: Ensure the storage area is at a stable temperature. Extreme temperature fluctuations can affect the properties of the materials, particularly the solid lubricants.

2. Avoid Mechanical Damage:

   • Careful Handling: During transport and storage, handle the parts carefully to prevent any mechanical damage, such as scratches, dents, or deformations. These damages could impair the function of the bearing or wear plate, leading to premature failure when the components are in use.
   • Proper Packaging: Use cushioned or protective packaging when transporting to safeguard the components from impact or other physical stresses.

3. Chemical Exposure:

   • Protect from Solvents: Keep the components away from any organic or inorganic solvents, including oils, cleaners, and chemicals. Solvents can destroy the solid lubricant embedded in the bearing, significantly compromising its performance and longevity.
   • Avoid Contact with Harsh Chemicals: Ensure that the parts are not exposed to chemicals that could degrade the materials, such as acids or caustic solutions. Always store components in a controlled environment free from harmful subst
