The sleeve type linear ball bearing describ
12、ed in this International Standard uses balls which circulate in a number of closed loops in the cylindrical bearing that surrounds the shaft. Linear ball bearings are typically applied to meet one or more of the following criteria: smooth low-friction motion, free from stick-slip or chatter; low for
13、ce required to produce relative linear motion between the bearing and the shaft. These requirements, as well as others, can be met by appropriate use of the various linear motion rolling bearing types (closed sleeve type, adjustable sleeve type and open sleeve type). The appropriate selection of bea
