Product features of cross ball guide
Time:2023-03-13
The cross ball guide is a kind of linear guide with limited travel, which has precision rollers that can replace the orthogonal arrangement. This product can provide rigid and flexible linear motion, especially suitable for linear guidance in situations requiring high rigidity and flexible motion. The product array cross ball guide VR adopts the common roller stick method to increase the effective touch length of the roller and shorten the roller pitch distance of the roller cage R. It is a high rigidity type. The ball guide VB type makes the precision steel ball adhere to the ball cage B type with short pitch distance, low friction and high precision.
The cross ball guide increases the effective touch length of the roller body by selecting the common roller holding mechanism of the R-type roller cage which shortens the distance between the roller bodies. Through the combined planning of roller cage and special V-shaped track, its high-precision surface is subject to special heat treatment, which is a high-rigidity, rigid-precision and compact finite linear motion system. Ball guide (VB type) is a product that replaces the roller body of cross ball guide with steel ball.
The equipment height of the cross ball guide rail is lower, so the two parallel equipment of the guide rail are combined into a set, which makes the machine integrity of the cross ball guide rail better than the linear guide rail, and the overturning torque is also higher than the linear guide rail. Therefore, the stability of the machine is much higher than that of the linear guide rail.
However, the effective travel of the cross ball guide is limited, and it is not as good as the infinite splicing of the linear guide. Within the limited travel, the reciprocating linear motion accuracy of the cross ball guide is much higher than the SP level of the linear guide. Therefore, it can be said that the precision of cross guide rail is much higher than that of linear guide rail.
Cross-ball guide rail is widely used in OA machine and its peripheral machines, various testers, printing substrate tapping machines and other precision machines, or optical testers, optical worktables, operating mechanisms, X-ray equipment and other slide parts.
