introduction：The difference between linear guide and linear bearing： （1）In terms of cost：Same brand，Linear guides are more expensive than linear bearings（Domestic imitation does not count） （2）In terms of equipment：Linear guide rails are more accurate than linear bearings，Greater load，More stable （3）From the market：Linear guide rails are more applicable than linear bearings，Linear bearings are relatively only suitable for primary machining Linear guide（ VAV linear slider）Can be divided into：Roller linear guide，Cylindrical linear guide，Ball linear guide，Three kinds of，In Shanghai Xionglian precision Machinery Parts Co., LTD. Linear guides are used to support and guide moving parts，Reciprocating straight motion in the given direction。It depends on the frictional nature，Linear motion guides can be divided into sliding friction guides、Rolling friction guide、Elastic friction guide、Fluid friction guide and other types。 Linear bearing is a self-lubricating linear motion system，The biggest difference with linear bearings i

introduction：Camshaft overhaul （1）Check camshaft curvature。With both ends of the journal as the fulcrum，Radial runout should not be done0.03mm，super0.1Ommwhen，Can be corrected by cold pressure correction method。 （2）The lift of the CAM is not less than the specified value5%when，Allow no grinding CAM，But the CAM base circle should be checked、Radial run-out tolerance of CAM base circle to camshaft axis；The overhaul standard is0.03mm，The overhaul is not greater thanO.05mm。 （3）The surface of the CAM is rough、wounded、Pitting should be trimmed。CAM tip wear exceeds1.00mmwhen，The CAM tip should be polished after surfacing welding，To restore the original size and shape，Or replace。 （4）Oil pump driving gear on camshaft，If the tooth surface is rough or the tooth surface wear exceeds0.50mm，Should be repaired。Some teeth of the gear are damaged，Without affecting the use of the condition，Allow to continue to use after grinding off acute angles。The surface roughness of the eccentric wheel driving the oil pump shall not exceedO.80μm。Eccentr

introduction：THKLinear bearings are now more and more widely used in electronics、Food machinery、Packaging machinery、Medical machinery、Printing machinery、Textile machinery、machine、instrument、Robot、Tool machinery、Numerical control machine tool、Automotive and other general or special machinery industry。 THKLinear bearing is a linear motion system produced at a low cost，For use with infinite stroke and cylindrical shaft。Because the bearing ball is in point contact with the shaft，So the use of small load。The steel ball spins with very little friction resistance，Thus, high precision smooth motion can be obtained。 THKLinear bearings are used in conjunction with quenched linear drive shafts。A system of infinite linear motion。Load the ball and quench the drive shaft because it is point contact，Less allowable load，But when moving in a straight line，Minimum frictional resistance，High precision，Fast movement。
