RGH25HA Linear Guide

RGH25HA Linear Guide

Product Description

The RGH25HA is a premium, industrial-grade linear motion carriage engineered for applications that demand the highest levels of structural stiffness and load-bearing performance. As a cornerstone of the RG Series, this block utilizes precision-ground cylindrical rollers in place of standard ball bearings.
 

• The Power of Line Contact:

By shifting from "point contact" (balls) to "line contact" (rollers), the RGH25HA significantly minimizes elastic deformation under load. This transition results in a dramatic increase in rigidity and unyielding stability, making it the definitive choice for precision-critical industries.

• The "HA" Advantage:

The "HA" designation signifies our Super-Heavy-Load configuration. Featuring an elongated block body, the RGH25HA provides an expanded contact surface with the rail. This increased length houses more rollers, providing a significant boost in both static and dynamic load capacities while delivering superior vibration damping. Whether for heavy-duty milling or massive precision positioning axes, the RGH25HA provides the unshakeable foundation your machinery requires.

Operating Principle: The High-Rigidity Roller Recirculation System

1.Optimized Load Distribution:Pay-loads are transferred to the 25mm rail through four rows of precision cylindrical rollers. This architecture ensures balanced force absorption across the entire block assembly.
2.The Line-Contact Advantage: Unlike ball-type guides that rely on point contact, the RGH25HA utilizes Line Contact. By spreading the load along a linear surface, the system drastically reduces contact pressure, effectively eliminating the "pitting" and raceway fatigue common in standard ball guides under heavy stress.
3.Endless Recirculation Geometry: Rollers traverse precision-ground load-bearing tracks and are seamlessly redirected by high-impact, low-friction resin end caps into internal return channels. This creates a continuous, low-friction loop for unlimited linear travel.
4.Enhanced Dynamic Stability: The elongated "HA" block geometry ensures a higher volume of rollers remain in the load-bearing zone at all times. This maximizes the block's "moment of inertia," preventing pitching or rocking and maintaining absolute stability even under uneven or cantilevered loads.
