CNC linear guides fall into three practical families — ball-type profile rail, miniature profile rail, and self-lubricating profile rail — and the right one for a given machine depends less on the machine's name than on its load pattern, duty cycle, and how clean the environment around the axis actually is.
A linear bearing is any component that lets a carriage move in a straight line while carrying load — the category splits into rolling-element (ball) types and sliding (plain/bushing) types, then further into profile rail, round supported rail, and unsupported shaft configurations.
Water cooling and air cooling solve the same problem — keeping a spindle motor from overheating — through different trade-offs. Water cooling handles sustained, heavy cutting loads but adds a pump, tank, and hoses to maintain. Air cooling needs less support equipment but tolerates less continuous load before performance drops.

The fundamental difference lies in […]
Rack and pinion earns its place when the axis is long enough that a ball screw would need a larger diameter, a support scheme, or both to stay below its critical speed. Below that point, a screw usually gives better stiffness and positioning for less money. The crossover is a calculation, not a fixed number.
