Product Description:

In the VR model, precision rollers are ingeniously combined with mutually orthogonal roller retainers and used in conjunction with 90° V-shaped groove rolling surfaces set on dedicated tracks. By assembling two parallel rows of roller guides, this guide system can withstand loads in four directions. At the same time, applying pressure to the cross roller guide rail can obtain a seamless, high-rigidity and flexible sliding mechanism. The VB type is a ball retainer B type that holds precision steel balls together at short pitch intervals and combines with a dedicated track V type to become a low-friction, high-precision finite linear motion system. Cross roller guides and ball guides are widely used in office equipment and its external devices, various measuring instruments, precision machines such as printing substrate drilling machines, and sliding parts of optical measuring equipment, optical workbenches, control mechanisms, X-ray devices, etc.

Technical Parameter:

Applicable scenarios:

With its excellent performance characteristics, this product plays an important role in many fields. In office equipment and its external devices, it ensures the precise operation and stable running of the equipment. In various measuring instruments, it provides a guarantee for the accuracy of measurement. In precision machines such as printing substrate drilling machines, it improves processing precision and efficiency. In fields such as optical measuring equipment, optical workbenches, control mechanisms, and X-ray devices, it meets the sliding requirements of high precision and high stability.

Product Function:

Long service life and high rigidity: By adopting a unique roller holding method, the effective contact length of the rollers is increased by 1.7 times compared to traditional products. Due to the shorter pitch spacing and increased number of rollers, the rigidity is increased by 2 times and the service life reaches 6 times. This enables full consideration of vibration and impact issues when designing linear motion components to ensure safety.

Smooth movement: In the VR type, each roller is separated and held by a cage. The roller bag in the cage is in surface contact with the roller, resulting in good lubricant retention, low wear, and smooth rolling movement.

High corrosion resistance: The VR and VB series offer stainless steel models with excellent corrosion resistance.

High precision and low friction: As a rolling guide, the THK linear guide VR 1 - 40×10Z enables the load platform to move easily along the guide rail with high precision through the infinite rolling cycle of steel balls between the slider and the guide rail. The friction coefficient is reduced to one-fiftieth of that of traditional sliding guides, achieving high positioning accuracy.

Multi-directional load-bearing capacity: The final unit design between the slider and the guide rail enables the linear guide rail to simultaneously bear loads in all directions, including up, down, left, and right.

Smooth operation and low noise: The patented return system and simplified structural design make the linear guide rail move more smoothly and with lower noise.
