The THK Cross Roller Table Mounting Hole Model VRU SERIES represents a high-precision linear motion solution engineered for applications demanding exceptional rigidity, accuracy, and smooth operation. This series integrates a cross roller mechanism within a compact table design, featuring pre-drilled mounting holes that simplify installation and enhance versatility in machinery layout. The core of its construction utilizes precision-ground surfaces and high-carbon chromium bearing steel rollers arranged in a crossed pattern at 90-degree angles, ensuring minimal deformation under load and consistent performance even in high-moment environments. Each unit is pre-loaded to eliminate backlash, providing unwavering stability for repetitive tasks.

Key technical features include the incorporation of THK’s proprietary cross roller guide technology, which distributes loads evenly across multiple contact points, significantly reducing friction and wear. The mounting holes are strategically positioned to allow for direct attachment to machine bases or moving parts, facilitating seamless integration without additional adapters. With accuracy grades up to ±5μm per 300mm travel and repeatability within ±1μm, the VRU SERIES maintains tight tolerances essential for precision-driven processes. Its sealed design, often equipped with grease nipples or optional seals, protects against contaminants like dust and chips, extending service life in harsh industrial settings. Available in various sizes and stroke lengths, it supports customization to meet specific load capacities—ranging from light-duty to heavy-duty applications—while maintaining a low profile for space-constrained installations.

Performance advantages of the VRU SERIES stem from its optimized roller geometry and hardened steel components, which collectively enhance stiffness and damping characteristics. This results in superior vibration resistance, reduced noise levels, and smoother motion compared to conventional ball-based systems. The high rigidity minimizes deflection under combined loads (radial, reverse radial, and moment loads), ensuring positional accuracy during high-speed operations or abrupt directional changes. Low friction coefficients contribute to energy efficiency, reducing power consumption and heat generation, while the maintenance-friendly design allows for easy relubrication without disassembly. These attributes translate to prolonged operational life, reduced downtime, and lower total cost of ownership.

Typical applications span industries where precision and reliability are non-negotiable. In industrial machinery, the VRU SERIES is deployed in CNC machining centers for tool positioning, semiconductor manufacturing equipment for wafer handling, and assembly robots requiring precise linear guidance. Automotive systems leverage these tables in automated welding fixtures, engine component testing rigs, and brake assembly lines to maintain tight tolerances under dynamic loads. Within precision equipment, they are integral to optical alignment devices, medical imaging systems like CT scanners, and coordinate measuring machines (CMMs), where sub-micron accuracy ensures diagnostic or measurement integrity. By combining robust construction with meticulous engineering, the THK VRU SERIES delivers a dependable foundation for advancing automation and precision across diverse sectors.
