The roller cross guide pair is composed of two guide rails with V-shaped raceways, roller cages, cylindrical rollers, etc. The cylindrical rollers arranged in a cross pattern move back and forth on the precision ground V-shaped raceway surface, which can withstand loads in all directions and achieve high-precision and smooth linear motion. After heat treatment and ultra-low temperature treatment, the track is precision formed and ground into V-shaped grooves to form a high-precision linear moving body. A limited stroke linear motion system with high rigidity, medium to heavy loads, and agile movements. ）

Has the following characteristics:

1. Low rolling friction resistance and good stability performance;

2. Low starting friction and good follow-up performance;

3. Large contact area, small elastic deformation, multiple effective moving bodies, easy to achieve high rigidity and high load movement;

4. The structural design is flexible and easy to install and use.

5. Control the positional tolerance within 0.01mm; Control the carbon layer within 0.8mm-1.2mm;

Purpose:CNC lathes, CNC milling machines, CNC engraving and milling machines, hydraulic lathes, electric discharge machines, wire cutting machines, projector measuring instruments, etc.

The cross roller guide rail VR type is a combination of a unique roller holding method that increases the effective contact length of the rollers, shortens the roller pitch interval of the roller holder R type, and a specialized track V type precision ground and processed after special heat treatment, with high rigidity. high-precision. A small limited form linear motion system.

Cross roller guide rails are widely used in precision machines such as OA machines and their peripheral machines, various measuring instruments, printing substrate drilling machines, or in the sliding parts of optical testers, optical workbenches, control mechanisms, X-ray devices, etc.

Cross roller guide rail structure and specialties:

The VR type cross roller guide rail is a combination of a roller holder that combines precision rollers in a straight and intersecting manner with a 90 ° V groove roller moving surface set on a dedicated track. By assembling the two rows of roller guides in parallel, they can withstand loads in all directions perpendicular to the axis. Moreover, due to the simple application of preloading, a seamless, highly rigid, and agile sliding mechanism can be obtained. The cross roller cage adopts imported alloy steel frame and precision grade steel column, suitable for high-speed operation and not easy to drop the steel column.

1. Long lifespan and high rigidity

By using a unique roller holding method, the effective contact length of the rollers has increased by 1.7 times compared to previous products, and the pitch interval of the rollers has become shorter, the number of rollers has increased, and the rigidity has increased by 2 times, resulting in a lifespan of 6 times. Therefore, for the vibration and impact issues that are prone to occur in straight motion parts, safety considerations can be fully considered in the design.

2. Smooth motion

In the VR type cross roller guide rail, each roller is separated by a cage. Due to the surface contact between the roller bag in the cage and the roller, there is good lubricating oil retention, so there is no wear, low friction, and smooth rolling motion can be obtained.

3. Excellent corrosion resistance
