introduction:BGCSuitable for high-speed operation: Linear rail without chain strapThe ball rotates between the slide rail and the slide seat。The relative speed of the resulting ball points is twice the speed of each other。The linear slide without a chain is the point contact between the steel ball and the steel ball。So the contact areaAVery small。Therefore surface pressure(P)Approaching infinity(P=The steel balls push against each other(F)/Contact areaA)。Therefore, the steel balls of the strainless linear slide rail are easy to wear each other。whileBGCSeries is the oil film in the middle of the ball retainer。The resulting friction is absorbed by the oil film,So in the use of speed can be used at high speed。
