Six Basic Parts

GIB SCREW – These are special socket head screws, properly spaced along one side of the saddle for adjusting the gib.

GIB SCREW NUT – The gib screw nut locks the gib screw in place to maintain the adjustment on the gib.

LUBRICATION FITTING – The lubrication fittings are standard on all slide assemblies except the "L" section basic and lead screw series. Passages drilled in slide allow lubricant to get to vital way surfaces to reduce friction and insure long life. Lubrication fittings can be easily removed and proper meter fittings installed for connection to an automatic lubrication system. (Mobil Vactra #2) oil or equivalent is recommended for lubricating slide ways.

SADDLE – The saddle is generally the moving member and has the female part of the dovetail.

GIB – This part may easily be adjusted to regulate the clearance between the way surfaces. The gib is adjusted at the factory before shipping to suit most applications; however, in some cases, a tighter or a looser setting may be desired. This can easily be accomplished in the field. Gibs are manufactured from accurately ground, low carbon steel and are equal to the saddle length.

BASE – The base is generally the stationary member and has the male part of the dovetail.

DO NOT USE GREASE!

Use these charts and formulas as a guide to determine the lube area or the amount of lubrication required for the slide. Lubrication requirements may vary depending on your application. Consult our factory for further assistance.
