Linear Guideway Type VR1-5Z
The Features of Crossed Roller Guides and Ball Guides
In the ZTVR type, the roller retainer with precision rollers arranged orthogonally is combined with the 90-degree V-shaped groove rolling surface set on the dedicated track. By assembling two rows of roller guides in parallel, the guide system can withstand loads in four directions. Moreover, since pre-load can be applied to the crossed roller guide, a gap-free, high-rigidity, and smooth sliding mechanism can be achieved.
The VB type is a limited linear motion system with low friction and high precision, which combines the ball retainer B type that holds precision steel balls at short pitch intervals with the dedicated track V type. Crossed roller guides and ball guides are widely used in the sliding parts of precision machines such as office equipment and their peripheral devices, various measuring instruments, printed circuit board drilling machines, optical measurement equipment, optical tables, control mechanisms, X-ray devices, etc.
【Long Service Life and High Rigidity】
By using a unique roller retention method, the effective contact length of the rollers is increased by 1.7 times compared to traditional products. Moreover, due to the shortened pitch interval of the rollers and the increased number of rollers, the rigidity is doubled and the service life is extended by six times. Therefore, for the vibration and shock problems that are prone to occur in the linear motion section, a fully safe design can be achieved.
【Smooth movement】
In the VR type, each roller is separated and retained by a cage, and since the roller pockets in the cage have a surface contact with the rollers, they have good lubricating oil retention, resulting in less wear and smooth rolling motion.
【High corrosion resistance】
The VR and VB series also offer stainless steel types with excellent corrosion resistance.
Types of Crossed Roller Guides / Ball Guides
Crossed Roller Guide ZTVR Type
This is a small, high-rigidity linear motion system in which the precision rollers are arranged perpendicularly in a cage and only move along the V-shaped groove of the track for half of the stroke.
Ball Guide ZTVB Type
This is a low-friction, high-precision linear motion system in which precision steel balls are retained by a ball retainer with short pitch intervals and only move along the V-shaped groove of the track for half of the stroke.
