Rolling bearing shutdown check

Core Tip: Regular inspection of the bearing seal is an important part of maintaining the bearing in the best condition. The most favorable inspection time is scheduled during the periodic shutdown inspection period. The importance of clean bearings: keeping the shaft
    Regular inspection of the bearing seal is important to maintain the bearing in the best condition. The most favorable inspection time is scheduled during the periodic shutdown inspection period.
    The importance of clean bearings:
    It is important to keep the bearings and lubrication clean.
    Clean the surface of the machine before inspection and then remove the parts around the bearing. The oil seal is a very fragile part, so be careful to disassemble it. Do not apply excessive force. Then carefully check the oil seal and its surrounding parts. If it has been shown to be bad, be sure to replace it. A bad oil seal will cause the bearing. Damage and resulting equipment downtime.
    Check lubricant
    Apply a point of lubricant to the friction between the two fingers. If any contaminants are present, feel it, or apply a thin layer of lubricant on the back of the hand, then seal the light.
    Replacement of lubricant
    Oil-lubricated bearings, after draining old oil, if possible, refill with fresh oil and allow the machine to spin at low speed for a few minutes. Whenever possible, the oil collects the contaminants from the wreckage and then vents the oil. The oil is preferably filtered before use.
    Grease-lubricated bearings should avoid any contact with the cotton material when replacing the grease, as these residual fibers may wedge between the rolling elements and cause damage, especially for small bearings. Pay attention to this issue.
    Covering exposed bearings
    When inspecting bearings, never expose the bearings to contaminants or moisture. If the work is interrupted, cover the machine with a piece of oil-paper plastic or similar material.
    If the unshielded bearing is cleaned without performing disassembly and may be inspected, it should be cleaned with a white spirit with a brush for application, then dried with a lint-free cloth or blown dry with compressed air. (Be careful not to let the bearing assembly start to rotate).
    Check the track faces, retainers and beads of the bearing with a small mirror and a probe similar to that used by dentists. If the bearing is not damaged, relubrication should be performed as recommended by the machine's original lubrication instructions.
    Do not clean the bearing with a sealing cover or dustproof; just wipe the outer surface.
    If the bearing is damaged, it needs to be replaced. Replacing bearings during regular downtime maintenance is far more economical than the loss of sudden downtime due to bearing damage.

Self-lubricating bearing lubrication mechanism

Core Tip: The unique lubricity and wear resistance of CSB-EP series materials is mainly due to the addition of reinforcing fibers, lubricants and other improvers to thermoplastic engineering plastics. by
The unique lubricity and wear resistance of CSB-EP series materials is mainly due to the addition of reinforcing fibers, lubricants and other improvers to the thermoplastic materials of the host material. Due to the thermoplastic composite material, the CSB-EP series is a highly wear-resistant crystal mesh structure with a special lubricant evenly distributed in the mesh.

    Due to the self-lubricating properties of the CSB-EP series of materials, no additional lubricant is required in use. The good self-lubricity of the CSB-EP series and the overall product are lubricated materials, so the product has a long service life; for coated, composite and impregnated metal products, once the friction layer or lubricating oil is exhausted, The end of life is over.

    The most critical moment for any bearing is the start-up phase. At this time, the lubricating film has not been formed and the bearing starts to work, which is the most common case. As long as the bearing is working under load, the bearing will produce subtle wear. In the start-up phase, when the fine wear is sufficient, the outer surface of the shaft is filled with these fine wear particles, so that an optimal lubricating film can be produced with low wear. After startup, the subtle wear drops rapidly and these changes have little effect on the size. In the continuous work after the start of the start-up phase, the wear rate is small and stable.
