Low-cost FDA/USDA/3A dairy compliant Water Dog linear slides

January 18, 2017 By Lisa Eitel Leave a Comment

FDA/USDA/3A-Dairy compliant, Water Dog Sliders from LM76 feature Corro-Slick coated 300 series stainless steel rails and contoured WDX Polymer blocks.  Water Dog Sliders can be washed down with the most aggressive chemicals and caustic foaming agents and have an operating temperature range of – 400O to +180 OF.  Quiet, low maintenance Water Dog Sliders can be used: Dry, submerged in liquids, and in refrigerated and frozen environments.

The hard Rc78 Corro-Slick coating applied to the 300 series stainless steel rails is exceptionally corrosion and wear resistant.  The coating under a microscope appears as small extremely hard spheres which results in a reduction in the coefficient of friction.  The Corro-SlickTM coating which becomes an integral part of the rail is not subject to cracking or micro-fractures with deflection of the rails.

Widely used in packaging, food processing, pharmaceutical, bio-pharma, bottling, medical, and dairy industries the smooth WDX Polymer as used in Water Dog Sliders has a very low coefficient of friction, does not absorb fluids, is self lubricating, is FDA/Caustic Wash Down compliant, and prevents debris from adhere to it’s surfaces.

Water Dog sliders are available in two sizes. WD1 rail and block assemblies measures just 1.02 inches x 1.00 inches high.  Standard off-the-shelf rail lengths are 12, 24, 36 and 48 in., and standard stock lengths of 157 in. are available.  The WD1 blocks are 1.00 in. wide x 0.75 in. high x 4.00 in. long with two Stainless Steel anchors threaded for 1/4-20 screws.  Rails are drilled on 3.15 inch centers for easy integration into a processing system and are designed for side loads up to 179 lbs and vertical compression loads of 89 lbs.

WD2 rail and block assemblies measures just 1.57 in. x 1.125 in. high.  Standard off-the-shelf rail lengths are 12, 24, 36 and 48 in., and custom length to 122 in. are available.  The WD2 blocks are 1.50 in. wide x 1.00 in. high x 5.250 in. long with four Stainless Steel anchors threaded for 1/4-20 screws.  Rails are drilled on 3.15 inch centers and are designed for side loads up to 258 lbs and vertical down loads of 178 lbs.


LM76 also manufacturers a broad variety of FDA/USDA/3A-Dairy compliant bearings and shafting, in inch sizes of .25 inches to 1.5 inches, and a FDA/USDA/3A-Dairy compliant profile rail and slide system that can easily be integrated into new and existing applications.  The bearing options include: Self-lubricating FDA/USDA/3A-Dairy compliant PTFE composite bearings in a 304 stainless steel shell, and lower cost bearings with a ceramic coated shell and FDA/USDA/3A-Dairy compliant liner.  Bearings are available in closed and open configurations, and are drop-in replacements for all inch sized linear ball bearings.
