BRH35A linear guides, combined height of 48, the carriage pitch 82 × 62, slide pitch 80mm. Linear guide for linear reciprocating motion of occasions, has higher rated than the linear bearing load, and can assume certain torque, high-precision linear motion can be achieved under high load conditions. Linear guide is a guide roll, which consists of the ball between the slider and the guide rail for rolling an infinite loop, such that the load platform can easily with high accuracy linear motion along the guide rail, 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 and the rails so that the linear guideway can withstand vertical and horizontal loads in all directions, return of the patent system and streamline the structure design allows linear rail has more smooth and low noise movement. When the load or pre-load is applied, for the two-point contact with the ball. Since the sliding trace is very small, and therefore, the balls run smoothly. Since the radius of curvature of the guide rail of 52-53%, it can withstand high static loads. Rail structure ideal two-point contact provides sufficient pre-load, therefore, has high rigidity. Special sealing design prevents dust from entering, but also to prevent oil spills, extended service life. Linear guide: 1, 2 low price, prompt delivery 3, 4 precise location accuracy, saving production and electricity costs by 5, 6 long time to maintain high accuracy, easy to install 7, to improve mechanical reliability. Linear guide machine tools, CNC machining centers, important features sophisticated electronic machinery indispensable, linear guide series saves power consumption and high speed operation, enhanced the production efficiency of machinery.
