Linear guide bearing is a common term used by some people, generally referring to linear optical axis (including various flange linear bearing blocks), linear guide optical axis, linear circular guide rail (including sliding unit of linear guide bearing seat assembly and flange type guide shaft support).

Linear guide and linear guide bearing are fundamentally two product accessories. Linear guide is an accessory for transmitting motion, and the reciprocating linear motion of the track from a specified point to the next point is the guide rail. The appearance of the linear guide bearing is significantly different from the outside of the linear guide: the guide shaft of the linear guide shaft bearing is in the shape of a rolling barrel; The axis of the linear guide is a square structure.

Linear optical axis is a type of linear motion system used in conjunction with linear bearings and cylindrical shafts. Due to the contact between the bearing ball and the outer sleeve of the bearing, the steel ball rolls with small frictional resistance. Therefore, the linear optical axis has low friction, and the electric push rod is relatively stable, not changing with the bearing speed, and can achieve stable linear motion with high sensitivity and accuracy. The consumption of linear optical axis also has its limitations, mainly due to the poor impact load capacity and load-bearing capacity of linear bearings; Secondly, linear bearings experience significant vibration and noise during high-speed motion.

Linear guide bearings and linear guides have similar functions, both supporting and guiding. The main difference lies in their installation location: linear guide bearings are generally fixed at both ends, with suspended connecting components in the middle covering all or most of the radial axis of the optical axis; Linear guide rails are generally fixed with bolts, with one side tightly attached to the equipment installation base.
