GGC Miniature Linear Guide |
GGC miniature linear guide adopts two-row ball cycle design, raceway design into a Gothic structure, its contact angle is 45°, in order to achieve the effect of four directions of equal load, through optimization design, under the limited space restrictions, the use of large size steel ball to improve the load capacity, fully show the function of high load and high torque.

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.
