RGH30CA Linear Guide

RGH30CA Linear Guide

Product Description

The RGH30CA is a premium linear motion component engineered for industrial environments where traditional ball-type guides are insufficient. By utilizing precision-ground cylindrical rollers as rolling elements, the RG series achieves significantly higher structural rigidity and load-bearing capacity than ball-type alternatives.

Series: RG Series (Ultra-High Rigidity Cylindrical Roller Type).
Size: 30mm (Compatible with RGR30 rails).
Rolling Elements: Cylindrical Rollers (Line Contact) for 30% higher stiffness than ball types.
Mounting: Square-type configuration for secure top-mounting.
Performance:

• Extreme load capacity with minimized elastic deformation.
• Superior vibration damping for improved surface finishes in machining.
• High-grade steel construction for extended service life.

Ideal For: CNC milling/boring machines, high-load automation, and precision lathes.

Core Engineering Advantages
1. Symmetrical 4-Way Load Capacity (45° Contact Angle)
The RGH30CA features an advanced four-row cylindrical roller configuration arranged at a symmetrical 45-degree contact angle.

• The Benefit: This optimized geometry ensures uniform load-carrying capacity and high-rigidity performance across all four primary directions: radial, reverse-radial, and lateral. This omni-directional stiffness allows engineers total freedom in mounting orientation-whether horizontal, vertical, or inverted-without compromising system accuracy or load stability.

2. Superior Operational Longevity
Traditional ball-type linear guides utilize point-contact geometry, which concentrates immense stress on small areas, making them susceptible to premature surface fatigue and spalling.

• The Benefit: By utilizing cylindrical rollers, the RGH30CA achieves "Line Contact" with the raceways. This significantly reduces peak Hertzian contact stress by distributing the load evenly along a linear surface. The result is a drastic reduction in material fatigue, ensuring a longer, more predictable service life even under continuous, heavy-duty industrial cycles.
