RGH45HA Linear Guide

RGH45HA Linear Guide

Product Description

The RGH45HA is a premium, industrial-strength linear motion carriage engineered for massive machinery and extreme operational cycles. As a flagship component of the RG series, it replaces traditional spherical balls with precision cylindrical rollers to provide a "Line Contact" interface. This architectural shift delivers load capacities and structural rigidity that far exceed those of standard ball-bearing guides.
 

The "HA" Elongated Advantage
The "HA" (Super Heavy Load) designation signifies an elongated block body (171.2mm) designed to house the maximum possible number of rolling elements. This expanded contact footprint ensures the highest level of stiffness and stability available in a 45mm profile.
Precision Under Pressure
Built to handle multi-ton forces, the RGH45HA maintains micron-level repeatability and unyielding accuracy even under high-torque cutting and pressing loads. It is the definitive solution for the world's largest CNC machining centers, heavy-duty bridge mills, and high-mass industrial automation systems where structural deflection is not an option.

Key Features & Engineering Advantages
1.Advanced Roller Technology: Utilizing precision cylindrical rollers, this series achieves high-density "Line Contact" geometry. This architectural shift delivers up to 30% greater structural stiffness compared to standard ball-type guideways.
2.Super-Heavy Load Capacity (HA): The elongated "HA" block is engineered for extreme industrial duty, boasting an exceptional 116 kN dynamic load rating to handle the most demanding payloads.
3.Unrivaled Moment Resistance: Specifically designed to neutralize structural stress, the RGH45HA handles monumental Pitch and Yaw static moments rated up to 4,200 Nm, ensuring zero-deflection performance on cantilevered axes.
4.Fortified Industrial Sealing: To ensure longevity in harsh environments, each unit comes equipped with high-performance double-lip end seals and integrated bottom seals, effectively blocking the ingress of abrasive dust, metal chips, and coolant.
