Ten basic parts

1. Lubrication fitting: For pressure gun lubrication; can be removed for manual or automatic lubrication systems, see accessories page. Lubricate with (Mobil Vactra #2) oil or equivalent.
2. Wiper: Provide protection to way surfaces from chips, dirt and other contaminants. Made from molded neoprene with a steel retainer.
3. Saddle*: Moving member and female section. Manufactured from 40,000 psi close grain cast iron normalized for maximum stability. Wear surfaces are lined with low friction bearing material, accurately ground and oil grooved to ensure adequate lubrication.
4. Retainer*: Retains the saddle to the base. Made from finish ground low carbon steel with wear surfaces lined with low friction bearing material.
5. Way: Saddle tracking wear surface. Manufactured from high carbon steel and hardened. Bonded and fastened to base before finish grinding.
6. Base: Stationary member and male section. Made from 40,000 psi close grain cast iron normalized for maximum stability.
7. Gib screw nut: Locks the gib screw in place to maintain the adjustment on the gib.
8. Gib screw: Special socket head screws properly spaced along one side of the saddle for adjusting the gib.
9. Gib postioning pin : For linear positioning of gib. Hollow pin mounted in lubrication hole.
10. Gib*: Adjustable member for setting side clearance between ways and saddle. Made from low carbon steel lined with low friction bearing material.

*Low friction bearing material has a coefficient of friction 1/3 that of cast iron on steel and similar dynamic and static coefficients which minimizes the stick-slip condition. Closer fits between the saddle and base can be obtained, which improves saddle tracking and positioning accuracy. Bearing material is standard on all HWS and HWL models. Slides without bearing material are available on request.

Caution: Low friction bearing material is not recommended in temperatures less than
-60°F or greater than +150°F, and when fluorine base coolants or chlorinated cutting oils are used.

Lubrication
(Mobil Vactra #2) oil or equivalent is recommended for lubricating slide ways.
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 factory for further assistance.
SL = Saddle length T = TRAVEL A = Number of lube points B = Way width(in.) C = Way height(in.) D = Lube factor (cc/hr. per in. SL + T) LB = Lube area/lube point top of way (in.2) LC = Lbue area/lube point side of way (in.2) LD = Lube req. (cc/hr.)
LB = [(SL)(B)(4)]/A       LC = [(SL)(C)(4)]/A       LD = (SL+T)(D)

Hardened steel way slide tolerances*

Overall height ………… = ± .005 in. Vertical tracking: …………………………… = .0005 in./3 ft. Horizontal tracking: …………………………… = .0005 in./3 ft. Parallelism: Saddle to base …………… = .001 in./ft.
* Higher accuracies available upon request.
