Linear Bearings - Load capacity: Hardness, finish, and conformity of race and rolling elements determine load capacity, which varies as the fourth power of the race Brinell hardness number. The surface finish must be smooth because grinding marks create ridges that prevent conformity between the race and rolling element. With a flat race, balls have lower load capacity than rollers and large-diameter balls have to be used to carry the same load. If the mating way is ground with either a Gothic arch or circular groove, the closer conformity to the ball allows the use of smaller balls than with flat ways. The Gothic arch approximates a V-type way with the load effectively split at angles of about 45? with the vertical into two loads on the way. The circular groove has a higher load capacity, but the ball bears on the bottom of the groove, which results in side play under loads normal to the line of motion. -Linear Bearings - Preloading -Linear Bearings - Life ratings
