OP).. It has the advantages of low friction resistance, low noise, low penetration force, corrosion resistance, etc. l Asian metric: standard (SDM), adjusted (SDM...AJ), open (SDM....AJ), open type (SDB.... It is widely used in electronic machinery, printing machinery, material handling machinery and various precision measuring instruments...
The structure is guided by the cage to make the steel balls do a very smooth circulation. The bearing outer cylinder is equipped with a cage, steel balls, side plates, etc.AJ), open (SDE..Features and uses of linear bearings Linear ball bearings are high-precision bearings that make rolling contact with a shaft and use the shaft as a track to make infinite linear movements in the direction of the shaft.OP) 2 European metric: standard (SDE), adjusted (SDE. Linear ball bearings have Asian metric system, European metric system and English system series, and each series has three forms, namely standard type, adjusted type and open miniature deep groove ball bearings suppliers type.OP) 3 Inch series: standard type (SDB), adjustment type (SDB
When the engine is overhauled, the crankshaft whose abrasion has exceeded the specified crankshaft should be repaired according to the repair size. After the main shaft journal and connecting rod journal wear, the roundness or cylindricity deviation is greater than 0. During actual repairs, in order to ensure the strength and rigidity of the crankshaft, the maximum reduction is generally not more than 1. The repair size of the crankshaft journal is at a level of 0.025mm, the crankshaft should be polished.06mm, the bearing seat hole should be repaired. The grinding of the crankshaft journal is carried out on a dedicated crankshaft grinder.25mm reduction.40μm, the diameter difference of each journal shall not exceed 0. If it is exceeded, it can be repaired by thermal spraying or surfacing
