RGH65HA Linear Guide

RGH65HA Linear Guide

Product Description

The RGH65HA is a premium, industrial-grade linear motion carriage engineered for applications where structural integrity and precision are non-negotiable. As a flagship component of the RG Roller Series, this block utilizes precision-ground cylindrical rollers to establish a high-stiffness "Line Contact" interface, significantly outperforming traditional ball-type guides.
 

Elongated Carriage for Superior Torque Resistance
The "HA" (Super-Heavy Load) designation signifies an elongated, robust block body. By increasing the carriage length, the RGH65HA maximizes the density of rolling elements within the load-bearing tracks, resulting in a staggering static load limit of 572.7 kN. This expanded structural base provides exceptional resistance to pitch and yaw moment loads, effectively eliminating torsional deflection on cantilevered or single-rail axes.
Engineered for Severe Industrial Environments
Constructed from high-grade alloy steel and finished to high-precision (H) accuracy standards, the RGH65HA is built to survive the most demanding manufacturing conditions. It features advanced internal end-cap recirculation paths for smooth, low-noise roller travel and is equipped with double-lip end seals to aggressively block abrasive metal chips, industrial dust, and cutting fluids, ensuring reliable, long-term performance.

Key Features & Engineering Advantages
Absolute Structural Rigidity: The extra-long roller track provides nearly zero-flex performance. This high-rigidity architecture ensures that even under multi-ton pressure, the block maintains micron-level positioning accuracy.
Unmatched Load Capacity: Engineered to move the industry's most demanding payloads, including entire machine columns, massive gantry beams, and heavy-duty worktables with ease.
Superior Vibration Damping: The high mass of the 65mm long-body block, combined with the extensive roller-to-rail contact area, effectively absorbs harmonic vibrations. This enhances tool stability, prolongs cutting tool life, and ensures a superior workpiece surface finish.
Exceptional Precision Longevity: Roller technology distributes mechanical stress evenly, effectively preventing the "pitting" and localized fatigue common in high-load ball guides. This design significantly extends the maintenance-free service life of the entire motion system.
Advanced Environmental Sealing: Equipped with a comprehensive sealing system-including reinforced double-lip end seals, side seals, and bottom seals-to lock out abrasive metal shavings, grit, and high-pressure coolants, ensuring reliable operation in harsh industrial environments.
