introduction:one、Electric erosion The electrical erosion of linear bearings is due to electrical leakage from the motor or electrical appliances,Electric sparks are generated between the friction surfaces of linear bearings,Cause spot marks on the friction surface,The characteristic is that the damage occurs repeatedly on the hard journal surface。 two、cavitation Cavitation of linear bearing is a form of surface damage caused by contact between solid surface and liquid and relative movement。When the oil is in the low pressure area of the oil film,Bubbles form in the oil,After the bubble moves to the high pressure area,Bubbles collapse under pressure,Great impact and high temperature at the moment of collapse,The solid surface under the repeated action of this impact force,The material falls off under fatigue,Make small pits on the friction surface,It develops into a spongy scar。Heavy load、High speed,And the load and speed change in the sliding bearing,Cavitation often occurs。

introduction:Yintai rail is also calledPMIGuideway orAMTrail,The steel seal of the Intime guide rail is printed on the side of the slide block,In allMSAHigh assembly series,,MSBLow assembly series,MSCandMSDmicroseries,SMERoller series and other series,Dimensions close to the upper silver rail,But block The color is popular silver black。Intime guide rails have interchangeable performance,You can change the slider or guide rail or even the whole linear guide。Standard models that can replace all brands of rails,Yintai guideway is another emerging product in the mainland market,Mainly used for machine tools,Robotic arm,Welding machinery,Handling machinery,Automation equipment and other linear transmission machinery。Yintai guide slide block is also divided into square type and flange type,Square type and flange type are also standard and lengthened,Short slider category。Preloading generally has light preloadingFC,Intermediate precompressionF0,repreloadF1,Slide rail types are divided into countersunk holesRAnd threaded passT,
