How much do you know about linear guides?

Linear guide rail, also known as slide rail, linear guide rail, linear slide, can be divided into linear guide roller, cylindrical linear guide rail, ball linear guide three, the former two speed slightly lower accuracy, the latter slow speed higher accuracy. Linear guide for linear reciprocating motion occasions, with higher than the linear bearing rated load, at the same time can bear a certain torque, can achieve high-precision linear motion under high load.

Application:

1, linear guide is mainly used in automated machinery, such as machine tools imported from Germany, paper bowl machine, laser welding machine and so on, of course, linear guide and linear axis is matched.

2. The linear guide rail is mainly used in the mechanical structure with high precision requirements. The moving element and the fixed element of the linear guide rail do not use the intermediate medium, but use the rolling steel ball. Because the rolling steel ball is suitable for high-speed movement, the friction coefficient is small, and the sensitivity is high, it can meet the working requirements of moving parts, such as the tool holder of the machine tool, the carriage, etc. If the force acting on the steel ball is too large, the steel ball is subjected to the preload for too long, resulting in an increase in the movement resistance of the bracket.
