To determine the NSK Bearings Can then:
    NSK Bearings in the judgment and remove the possibility of re-use, after bearing cleaning inspection, carefully check the raceway, the raceway, with the surface state of cage wear, bearing clearance and whether the impact of the size of the decline in accuracy damage, abnormal.
    Non-separation of small ball bearings, the inner flat side, with one hand, rotate the outer ring to confirm whether smoothly.
    , NSK Bearings replaced:
    NSK bearing the possibility of re-use when the judge, according to the damage of bearings, mechanical properties, the importance of operating conditions, check the cycle, and other related factors to decide. Check if any of the following defects are found, then the bearing can not continue to use the new bearings need to be replaced.
    An inner ring, outer ring, rolling body, keeping the frame in any one cracks or gaps;
    2, the ring, rolling body any one fracture;
    3, raceway, ribs, rolling on the obvious abrasions;
    4, cage wear is obvious, or obvious loose rivets;
    Raceway, rolling body rust or scars;
    6, raceway, rolling element serious indentation or bruising;
    7, the inner diameter surface or the outer ring outer diameter surface of creep;
    8, significant discoloration due to overheating;
    9, enclosed grease NSK bearings, seals dust cover badly damaged.
    Third, the separation of bearings overhaul:
    Tapered roller bearings, such as separation of bearings, rolling element, the outer ring raceway surface were examined.
    Fourth, the maintenance of large bearings:
    Large bearing because of the importance of hand rotation, pay attention to check the rolling element and raceway to maintain the appearance of the frame, ribs, face, bearing the higher the more need to be cautious check.
    Five, NSK Bearings damage Type:
    However, these damage types and the types of industries. For example, the pulp and paper industry is mostly due to poor lubrication or contamination caused by damage to the bearings, rather than due to material fatigue.
    Six, NSK Bearings damage reasons:
    Most of the bearing causes of damage. Beyond the original estimate of load, such as: non-effective sealing, tight with the result of small bearing clearance.
    Any one of the factors of these factors have their special damage type and will leave special signs of damage. Therefore, the view of damage to the axis of the bearing can be found in many failures, the possible cause of
    Generally speaking, one third of the bearing damage caused by fatigue damage, the other third due to poor lubrication, one-third of other causes of pollutants into the NSK Bearings or installation not handled properly.
    In summary, the master NSK Bearings judgment overhaul of the above criteria, bearing failure can quickly determine the state of bearing damage and timely repairs to make it return to normal operation.
