Is there any difference between precision cross guide and linear guide? What is the difference between the two? The precision guide rail manufacturer has compiled the following content for everyone. Friends, come and take a look!

Precision cross guide rail is composed of two guide rails with V-shaped raceways, a support frame, and a rolling body. The damping devices are arranged in a cross manner, and the rolling body moves back and forth on the precision ground V-shaped raceway surface. The electric slide table can accept loads from all directions and complete high-precision and stable linear motion.

However, the useful travel of precision cross guides is limited, unlike linear guides where the desired length is left as long as desired. Within the limited travel, the reciprocating linear motion accuracy of precision cross guides is much higher than the SP level of linear guides. Therefore, it can be said that the precision of precision cross guides is much higher than that of linear guides.

Precision cross guide rail is a combination of a rigid frame that combines precision rollers in a straight and perpendicular manner with a 90 ° V groove rolling surface set on a dedicated track. By parallelizing the two rows of guide rails, they can withstand loads in all directions perpendicular to the axis. Moreover, by simply applying preloading, a sliding seat structure with no empty space, high rigidity, and agile movement can be obtained.

In the cross guide rail, each rolling body is separated by the support frame. Due to the surface contact between the roller bag and the roller in the support frame, there is good lubricating oil adhesion, so there is no wear and minimal resistance, thus achieving smooth rolling motion.

It is widely used in precision machines such as OA machines and their peripheral machines, various measuring instruments, printing substrate punching machines, or in the sliding seat of optical testers, optical workbenches, operation organizations, X-ray equipment, etc.

The VB type ball guide rail is a B-type ball holder that uses short pitch intervals to hold precision steel balls together, combined with a dedicated V-shaped rail, with low resistance. A high-precision finite form linear motion system.

The equipment height of precision cross guide rails is lower, so the combination of two parallel guide rails forms a set, making the machine integrity of precision cross guide rails better than linear guide rails, and the overturning torque higher than linear guide rails. Therefore, the stability of the operating machine is much higher than that of linear guides.

The above is the relevant content about precision cross guide and linear guide that precision guide manufacturers have compiled for everyone. We hope it can be helpful!
