They can be divided into three types: roller linear guides, cylindrical linear guides, and ball linear guides. Linear guides are used in high-precision or high-speed linear reciprocating motion occasions, and can bear a certain torque. They can achieve high-precision linear motion under high load conditions. During the processing and production of linear guides, grinders are required to polish their surfaces and sides.
