The damage appearance of the bearing holder is not very obvious; under normal circumstances, it is not easy to distinguish. The bearing sensation; the speed exceeds the drawing requirement; the wear; the foreign matter jam and the tilt are the main reasons for the damage of the holder. Analysis of the situation:
1. A sensation when the bearing is in a sensation; the internal force of the bearing can cause the wearer to exhibit fatigue cracks. Gradually; this crack will break the holder. To avoid this appearance; bearings with special adherents can be used.
2, the speed exceeds the depiction demand if the bearing works at a speed beyond the persistence of the data; inertial force will lead to the break of the holder. There are high-speed bearings specially made for this occasion.
3. A smooth or strong foreign object that is not worn properly will cause the bearing to wear. The rolling bearing is most likely to have sliding friction when running. However, the sliding contact between the roller and the holder is usually impossible to eliminate; The stick is the worn part of the first battle. And the stick is made of softer material; so the wear is just as fast. The gradual adherence of the gap will cause the stick to break quickly. When the sturdy particles wear When entering the bearing; there will be the same situation.
4, the foreign matter stuck parts of the fragmentation or particles can be stuck between the holder and the roller. Prevent the rollover from rolling. This will also cause the crusher to break. As long as it can avoid large foreign objects invading the bearing; even in heavy load occasions The adherence can also be safe and sound.

Stainless Steel Washer

stainless steel commercial flat washers are used under bolt heads or nuts to increase the bearing surface area, or to offer protection so that the nut or bolt can be rotated without distortion of the bearing surface. Flat washers are also used to give tightness to a joint, to prevent leakage, and especially to distribute pressure under the head of a bolt or nut. Dimensional specifications are governed by ASME B18.21.1. Commercial flat washers generally have a larger outer diameter than SAE (Society of Automotive Engineers) flat washers, and can be utilized in nearly any application. stainless steel fasteners are commonly used in applications that require general atmospheric corrosion resist ance, such as chemical and food processing equipment. Stainless steel has a higher corrosion resistance than carbon steel.
