PRODUCT OVERVIEW GUIDE RAILS/CENTER RAILS

■ Example

■ Outline of dovetail guide rail

● Example of mounting groove

● How to mount • Make countersunk holes for mounting bolts and grooves for installing the rail on each of the base side and slide core side, and fix them with bolts. • Refer to the right diagram for the groove dimension. • If the slide core does not move smoothly, check the clearance and the groove pitch (parallelism) of the groove width and the rail width W and adjust it.
