RGH45CA Linear Guide

RGH45CA Linear Guide

Product Description

The RGH45CA is an industrial-grade linear motion carriage engineered for the most demanding manufacturing environments. As a flagship component of the RG series, it replaces traditional spherical ball bearings with precision-ground cylindrical rollers. This fundamental design shift transforms the internal interface from "point contact" to "line contact," delivering significantly higher load-bearing capacity and unmatched structural stiffness.

Engineering for Heavy Industry
The "45" designation signifies compatibility with massive 45mm linear rails, providing an unshakeable foundation for heavy machinery. The "CA" square-type configuration is specifically optimized for high vertical strength and secure top-down mounting. The RGH45CA is the definitive choice for large-scale CNC machining centers, heavy-duty automation gantries, and precision manufacturing systems that demand absolute positioning accuracy and zero tolerance for elastic deformation under peak loads.

Key Features
1.Cylindrical Roller Technology: By utilizing high-precision cylindrical rollers instead of spherical balls, the RGH45CA achieves "Line Contact" geometry. This significantly expands the contact surface area, delivering a massive increase in structural stiffness and load-bearing performance.
2.Omni-Directional 4-Way Load Capacity: Featuring a symmetrical four-row roller arrangement at a 45-degree contact angle, the RGH45CA maintains identical load ratings in radial, reverse-radial, and lateral directions. This ensures motion fidelity regardless of mounting orientation.
3.Precision Accuracy Grades: To meet diverse industrial demands, this series is available in High (H), Precision (P), and Super Precision (SP) classes, ensuring exact tolerances for high-end applications.
4.High-Rigidity Square Profile: The compact, non-flanged square design is engineered specifically for high-strength, top-down mounting, making it the ideal interface for heavy-duty worktables and gantry columns.
5.Industrial Load Ratings: Designed for extreme-duty cycles, the RGH45CA offers a basic dynamic rated load (C) of 92.6 kN and a static rated load (C0) of 178.8 kN.
