Linear guides, also known as line guides, slide rails, linear guides, and linear slides, are used in high-precision or high-speed linear reciprocating motion applications, and can bear a certain torque, and can achieve high-precision linear motion under high load conditions. Ball Linear guide is a kind of linear guide, linear ball bearing block is bearing of Ball Linear guide, Linear guide bearings are also called linear bearings, and are also a rolling component that can perform linear reciprocating operation.
