TriQuench HGR 20R 4000C BG Linear Rail | 20mm High-Precision Guide Track

The TriQuench HGR 20R 4000C BG is a premium linear guide rail designed for large-format industrial machinery where long-travel accuracy and structural integrity are paramount. Featuring a 20mm nominal width and a continuous 4000mm length, this rail provides a seamless, high-precision track for automated systems. Engineered with a four-row circular arc groove architecture, it ensures equal load capacity in all directions—radial, reversed radial, and lateral—while maintaining ultra-low friction travel. Manufactured from high-tensile alloy steel and induction-hardened to HRC58-62, the HGR 20R ensures long-term wear resistance and repeatable sub-micron positioning. Its self-aligning capabilities help absorb minor mounting surface deviations, making it the premier choice for heavy-duty CNC routers, automated stone cutting machines, and industrial plasma beds requiring surgical linear precision over long distances.

Technical FAQ

What is the benefit of a 4000mm continuous rail?

A continuous 4-meter rail eliminates the need for joints in long-axis machines like large CNC routers or bridge saws. This ensures consistent precision, prevents carriage wear at joint gaps, and provides a much smoother linear motion.

Can this rail be cut to a specific shorter length?

Yes, while 4000mm is the standard stock length, we can precision-cut the HGR 20R to your exact requirements. Please specify the desired 'E' values (end-hole distances) to ensure mounting symmetry.

How do I maintain the precision of these long rails?

Maintenance is essential. Keep the raceways free of debris using the carriage wipers and maintain a thin film of lithium-based grease. For rails of this length, ensuring the mounting surface is perfectly leveled and ground is critical for performance.
