NMB precautions for the use of miniature bearing, stainless steel series common models

NMB precautions for the use of miniature bearing, stainless steel series common models you've all heard of NMB miniature bearing, NMB is Japan's brand, the main products are precision miniature ball bearings NMB, all kinds of high precision machinery, electronic components, etc. As miniature bearing industry in the world's largest manufacturer, since 1951, successively introduced all kinds of precision bearing, widely used in the VCR, air conditioner, vacuum cleaners, auto motor. Today the author to introduce the NMB miniature bearing product knowledge, hoping to bring help! NMB miniature bearing use pay attention to the following items: 1) Keep the bearing and the surrounding clean. 2) When used carefully if careless to the bearing to strong impact when using, can cause a scar, indentation, bearing fracture, etc. 3) Use the right tools. 4) Pay attention to the bearing of rust. Avoid use in damp places, and to not make sweat stained, gloves should be worn. 5) The user should be familiar with the bearings. 6) Set bearing using the code of conduct.

Cooperate, refers to the shaft and the inner ring, between casing and outer ring of the assembly, the tightness of Mosaic. Can be divided into gap, interference and transition fit. As an object of cooperation to in order to prevent the creep into the purpose, in the event of creep, can produce abnormal fever due to sliding wear, or resulting from wear of the clastic blend into the bearing ablation or cause shorten service life. Although fit interference quantity can prevent the generation of creep, basic but must pay attention to when choosing interference quantity reduction of radial clearance ( Negative clearance) , bearing temperature distribution at runtime, Temperature changes when the amount of interference) And change ( The impact on the orbit roundness) And so on.
