Sphere bearing outside UKP202D1 bearing NSK
Overhaul and judge the method in order to maintain the original performance of the exterior sphere bearing with the good state as for a long time as possible in damage of the exterior sphere bearing, must maintain, overhaul, on right, guarantee dependability that turn round in order to defend accident, improve productive, economy. Had better maintain the operation or work standard of the condition that corresponding machinery operates, go on regularly. The content includes, the inspection monitoring the state of operating, supplementing or changing lubricant, dismantling regularly. Generally, if use the exterior sphere bearing correctly, can use to reach fatigue life. But there will be accidents that will be damaged too early, can’t be able to bear in the situation that use. This kind is damaged in early days, is opposite to fatigue life, use the limit to the quality known as trouble or accident. The ones that caused by and installed, used, lubricated going are careless more, foreign matter invaded from the outside, research of influence enough getting abundant as to axle, heat of outer cover. About the damage state of the exterior sphere bearing, for example: Wounded that one set of circles of the sub bearing blocks the card in the side to roll, can be considered as the reason, lubricant is insufficient, unsuitable, is for the defect, foreign matter invading, NSK bearing of arranging the oil structure to install the bending too big of the error, axle, also there are these coincident reasons. So, only investigate the bearing is damaged, very rare real reason to know to be damaged. However, if know using the structure around the machinery, service condition, bearing, understanding the situation before and after the accident happens of the bearing, damage state and several kinds of reasons for combining the bearing investigate, can prevent the similar accident from recuring. While judging whether the exterior sphere bearing could be used again, decide according to relevant factors such as damage intensity, mechanical performance, importance, condition of operating of NSK bearing, checking cycle,etc.. But find that there are the following defects while checking, then the bearing can’t continue using, need to change the new NSK bearing. (a)Inner circle, outer lane, rolling the body, keeping an arbitrary one in the shelf having crackle or gap. (b)One set of circles, rolling an arbitrary one in the body and rupturing. (c)Roll the surface, block, there is obvious abrasion on rolling the body. (d)Keep the shelf abrading obviously, or the rivet obviously becomes flexible. (e)There is corrosion or scar to roll in a surface, roll on the body. (f)Roll in a surface, roll on the body and there is serious compression or damage. (g)There is obvious creep the internal diameter of inner circle or the outer lane external diameter. (h)Obviously change color because of being overheated. (i)Enclose NSK bearing of lubricating grease, seal and enclose or overlay the damage dustproofly seriously.
Sphere bearing outside UKP202D1 bearing NSK

The name of product: The new type of the sphere bearing outside UKP202D1 bearing NSK: UCF318D1 use: The exterior sphere bearing is suitable for requiring apparatus and spare part simple occasion preferably, for example used in agricultural machinery, transportation system or building machinery. Mainly used for bearing radial and axial union load relying mainly on radial load, should not generally bear axial load alone, this kind of bearing can differentiate the inner circle of installation (bring to the whole group and roll son and keepers) With the outer lane. Type: Exterior sphere bearing
