Product Description

GGC Miniature Linear Guide

1. Product Overview

The GGC miniature linear guide features a mature and optimized two-row ball circulating design, which serves as the core foundation for its stable linear motion performance. Different from ordinary miniature linear guides with simple raceway structures, this product adopts a sophisticated Gothic arch raceway structure with a standard 45° contact angle. This professional structural configuration enables balanced and uniform load bearing in four directions, effectively solving the problem of uneven stress and unilateral wear common in traditional miniature guide rails, ensuring consistent and smooth operation in all motion directions.

To break the performance limitation of miniature guide rails caused by tiny installation space, the GGC series has undergone targeted structural optimization. Under the premise of retaining ultra-small and compact body dimensions, the guide is equipped with enlarged-size steel balls. This ingenious design makes full use of limited internal space, effectively upgrading the overall load-bearing performance and structural torsion resistance of the miniature guide, perfectly balancing miniaturization, high load capacity and high structural rigidity.

2. Application

With its ultra-compact structure, four-way equal load stability, excellent high-load and high-torque performance, the GGC miniature rolling linear guide is exclusively suitable for high-precision, high-end miniature mechanical equipment and precision detection systems. It is widely recognized for reliable precision output in sophisticated manufacturing and precision motion control fields.

Its typical application scenarios cover semiconductor manufacturing equipment, high-precision medical devices, optical precision platforms, professional precision inspection instruments, EDM wire-cut machine tools, and computer embroidery machinery. It fully meets the ultra-high precision, micro-space installation and stable load-bearing operation requirements of precision electronics, medical treatment, optical detection and special processing equipment.

Note:

1). MA.MB.MC in the table, as shown in the figure below on the right, refers to the rated static moment value of a slider.

2). Lmax in the table is the maximum length of a guide rail. For example, the length of the guide rail is to be negotiated separately (it is recommended that the guide rail be installed with holes).

3). If there is no special requirement for a single guide rail, the hole end distance is equal to both ends.
