Supporting the production of machinery and equipment installation of water delivery for linear reciprocating linear guide occasion, with a higher rating than the linear bearing load, and can assume certain torque, high-precision linear motion can be achieved in the case of high load. It is a rolling guide, by the ball between the slider and the guide rail for rolling infinite loop, so that the load platform can easily along the rails with high accuracy linear motion, the friction coefficient can be reduced to a conventional slide guide 1 / 50, so that it can easily reach μm-level positioning accuracy. End unit designed to slide between the rails, making the linear guide can withstand vertical and horizontal loads in all directions, the return of the patent system and streamline the structure of the linear guide rail design allows a more smooth and low-noise movement. When the load or pre-load effect for two-point contact ball bearing. Since the sliding trace is very small, and therefore, the balls can run smoothly. Since the radius of curvature of the guide rail is 52-53%, and therefore can withstand high static load. Guide structure for ideal two-point contact, provide sufficient pre-load, therefore, has a high rigidity. Special seal designed to prevent dust from entering, but also to prevent oil spills, extended service life. Supporting the production of machinery and transport equipment installation of water linear guide: 1, 2 low price, prompt delivery 3, 4 precise location accuracy, reduce production costs and electricity 5, 6 long time to maintain high accuracy, easy to install 7, improve the mechanical reliability . It is a variety of machine tools, CNC machining centers, important features indispensable precision electronic machinery in the series saves power consumption and high-speed operation can improve the production efficiency of machinery.
