A unique coating developed exclusively for Marathon® heavy-duty cast-iron mounted bearing units promotes superior and long-term resistance to corrosion. The proprietary coating covers all housing surfaces and insert bearings to offer maximum protection in rotating equipment applications for the food processing, meat, pork and poultry processing, and beverage industries, among others.
The ZMaRC® coating ultimately allows the bearing units to benefit from the strength and durability of cast iron while eliminating typical flaking problems associated with conventional nickel plating.
All Marathon units featuring the ZMarC coating integrate a patented dual-sealing system to promote extended bearing service life and inhibit potentially damaging contamination. The multifunction rubber seals are bonded to AISI 304 stainless steel for added corrosion resistance. Sealed-for-life lubricants (H1 grease) are USDA approved for food applications.
Coated Marathon bearing units are virtually maintenance-free and are available in several housing designs, including pillow blocks, two- or four-bolt flange, and tapped base. Open spaces on bases or backs of housings are filled with polyurethane to enhance sanitary housing design.
Made-to-Order (MTO) warranted products can be developed through MRC's dedicated MTO program. CAD drawings of standard products are available for downloading free from www.mrcbearingservices.com
