Miniature Profile Ball Rail Installation
REFERENCE SURFACE HEIGHT AND CHAMFERED
To avoid any interference, the corner of the reference edge should have a chamfer. If not, please refer to the following table for the height of the reference edge corner and the height of the reference edge.
THE MOUNTING SURFACE
Surface roughness â€“ the mounting surface should be ground or fine milled to reach a surface roughness Ra1.6.

GEOMETRIC AND POSITIONAL ACCURACY OF THE MOUNTING SURFACE
Inaccurate mounting surfaces will affect the operational accuracy of the linear guide. The rating lifetime will also be shortened. Insure the mounting surface height differential is greater than the values calculated by the formulas below.
Rail: Both sides of the track rail can be the reference surface without any special marking.
Block: Reference edge is opposite to the groove marking side.
