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.

NOTE
1. MA, MB, MC shown in the diagram respectively indicate rated torque of one block.
2. Lmax is the maximum length of one rail.
3. Distances from both ends to the hole in one rail are equal if there is no special requirement.
