Miniature Linear Guide

The GGC miniature linear guide uses a 2-row ball circulation design. It offers a Gothic profile designed with a 45º contact angle to achieve equal load in four directions. Through its optimized design, we can use larger balls in the limited space to improve the load carrying capacity of the miniature linear guide.

The miniature linear guide is made of bearing steel and has high accuracy, high speed, and high rigidity. The miniature linear guide offers a long service life and produces little noise. As a result, the miniature linear guide is used for semiconductor medical equipment, production equipment, inspection equipment, electro spark wire cutting machine, computerized embroidery machine, etc.

  • Radial Linear Guideway The radial linear guideway withstands force perpendicularly in the radial direction, so its radial load carrying capacity is greatly increased. Improvement on the fitness of raceway and roller helps improve the load carrying capacity and rigidity of each raceway. The radial linear guideway offers a reduced overall height and the optimizing structure with finite element analysis enables the mutual force points ...
  • Roller Guide Block Our roller guide block is a precision linear motion element, providing high load carrying capacity and rigidity. It achieves high sensitivity and highly functional plane linear motion. In the condition of heavy load and varied load, the roller guide block has small elastic deformation and can get stable linear motion without crawl. Our roller guide block is flexible to use, and is not restricted by the length of machine tools.
