Any improper lubrication of SKF bearings are inevitable failure in advance, because the plastic hub bearings are not easy assembly and disassembly of the site, while the use of an incorrect birth grease, while the latter does not replace the use of grease or grease deterioration occurred after contamination without carbonation timely replacement, your hub is difficult to have a sufficiently long life and good lubrication.

     Another reason for damage up to 16 percent, this is the improper assembly and loading errors or violent methods, making those bearing the load when it has undergone a smooth surface clang bowl percussion flawed.

     To make Peilin Ka tight shaft, to prevent friction phenomenon sleeve (this phenomenon in high-speed rotating machinery will instantly generate high temperatures, causing oil dry out even lead to heat up stuck, causing downtime), so that the inner bearing clang and the outer bowl (also known as industrial bearing housing) using a kind of "interference" phenomenon, that is popular within a pan large axial ratio, or the ratio of the outer bowl into big things, this requires a lot of strength interference can be loaded in, and this load on the bearings for percussion require great strength, which can cause bearing damage in the process of knocking, so the big industrial SKF bearings usually heated, hydraulic jacking into other ways.

     Bike using plastic sealed deep groove ball bearings, such bearings are most afraid of percussion (needle roller bearings and large bearing slightly stronger resistance on percussion), and also can not use the heating load method, but due to a bike Peilin of interference is very small, even such as Green Tree bearing hubs can hand put Ru Peilin, so use plastic hammer knock is relatively safe, but the thing into the top of the scapegoat, but needs a very flat surface, The use of static press, such as clamping vise, is the best way.

     The first noise associated with the bearing manufacturer: This includes noise and vibrato cage, cage noise occurs mainly in ball bearings and tapered roller bearings, SKF bearing rotation when the cage cage with vibration and shock occurred rolling will sound This sound has periodicity vibrato (various bearings) there is a certain frequency sound is due to a larger raceway waviness caused by vibration generated. This phenomenon is most common problem, we need a lot of attention since it can. In particular, we are learning some of the bearing knowledge of the students who want to carefully look over the content of these key, so you may find some help.

     The second noise caused by improper use: For a variety of SKF bearings are present when the bearing raceway surface or rolling surfaces are bumps, indentations, corrosion, it will produce a certain period of noise and vibration when the bearing in operation There are dirt dust intrusion will produce noise. This noise is also accompanied by a non-periodic vibrations of its sound size is not fixed, from time to time.

     Third inherent noise: the sound with a variety of bearing raceway and rolling friction sound (cylindrical roller bearings) are bearing the inherent sound raceway sound by rolling element and raceway contact of elastic properties generated when the SKF bearing swivel When rolling body raceway issued in a continuous and smooth voice; unusual sound of rolling friction may issue a "creak, creak" like uncomfortable metal friction abnormal sound, well-oiled will not issue such a sound, so is not a problem in general, after only pay attention to the noise increases.
