Vr1 Vr2 Vr3 Vr4 Vr6 Cage Xihu (West Lake) Dis.ways Cross Roller Linear Xihu (West Lake) Dis. Rail


Product Description

In the VR model, the precision rollers are combined with a roller retainer that is orthogonal to each other and is used in combination with a 90 ° V-groove rolling surface set on a dedicated track. By assembling 2 rows of roller guide rails in parallel, the guide rail system can withstand loads in 4 directions. Moreover, by applying preload to the cross roller guide rail, a sliding mechanism with no gaps, high rigidity, and light and fast movement can be obtained.

The VB type is a ball keeper B type that uses short pitch intervals to hold precision steel balls, combined with a dedicated track V type, and has a low friction, high-precision finite linear motion system.

Cross roller guide rails and ball guide rails are widely used in precision machines such as office equipment and its external devices, various measuring instruments, printing substrate drilling machines, or the sliding seats of optical measuring equipment, optical workbenches, control mechanisms, X-ray devices, etc.

Long service life and high rigidity
By utilizing a unique roller retention method, the effective contact length of the rollers has increased by 1.7 times compared to traditional products. Additionally, due to the shorter pitch interval of the rollers and the larger number of rollers, the rigidity has increased by 2 times, resulting in a 6-fold increase! The lifespan of. Therefore, for the vibration and impact problems that are prone to occur in linear motion parts, safety considerations can be fully considered in the design.
Smooth motion
In the VR model, each roller is separated and maintained by a cage, and due to the surface contact between the roller bag and the roller in the cage, there is good lubricating oil retention, so the wear is small and smooth rolling motion can be achieved.

What are the reliability and durability aspects of linear rails in ensuring consistent linear movement?

The reliability and durability of linear rails are critical for ensuring consistent linear movement in various applications. Here are key aspects that contribute to their reliability and durability:

  • Materials: High-quality materials, such as hardened steel or reinforced alloys, are used in the construction of linear rails. These materials provide the necessary strength, wear resistance, and durability to withstand the stresses of continuous linear motion.
  • Surface Treatments: Surface treatments, including coatings and finishes, are applied to protect the linear rails from corrosion, abrasion, and other forms of wear. These treatments enhance the longevity of the rails, ensuring they maintain their performance over time.
  • Lubrication: Proper lubrication is essential for reducing friction between the rail and carriage. Lubrication not only minimizes wear but also contributes to smooth and consistent linear movement. Lubrication intervals and the choice of lubricants impact the overall reliability and performance of the linear rail system.
  • Sealing: Sealing mechanisms are employed to protect the internal components of the linear rail system from contaminants such as dust, debris, and moisture. Effective sealing enhances the reliability of the system by preventing damage to critical components and minimizing the risk of malfunction.
  • Rigidity: The rigidity of linear rails is crucial for maintaining consistent linear movement, especially under varying loads. Rigidity prevents deflection or bending of the rail, ensuring that the carriage follows a precise and predictable path during operation.
  • Load-Bearing Capacity: The load-bearing capacity of linear rails is a key factor in their reliability. Properly sized linear rails that match the application’s load requirements ensure consistent performance and prevent premature wear or failure.
  • Manufacturing Precision: High manufacturing precision in the production of linear rails contributes to their reliability. Precise machining and assembly processes result in consistent dimensions and tolerances, ensuring that the rail and carriage components fit together seamlessly for reliable linear motion.

Reliability and durability go hand in hand in ensuring consistent linear movement over the lifespan of the linear rail system. Regular maintenance, including inspections, lubrication, and replacement of worn components, further contributes to the sustained reliability of linear rails in industrial and automation applications.
