New SealMaster® PN Gold bearings in metric sizes lead lineup of corrosion-resistant bearings solutions for the beverage industry

Special for Brau Beviale 2012. See Emerson in Hall 7, stands 7-518 and 7-617

Kontich, Belgium - November 7, 2012 - Emerson Industrial Automation will introduce its metric-sized SealMaster® PN Gold bearings at Brau Beviale as part of an extensive exhibit of sustainable bearing solutions engineered for the beverage industry. At Brau Beviale, Emerson's display will emphasize the CRES series (Corrosion Resistant Engineered Solutions) that includes SealMaster roller and ball bearings and McGill® Camrol® cam follower bearings. The company's Rollway® stainless steel bearings and System Plast mounted bearings for wash-down applications will be featured as well. “Bearings play a critical role in operational excellence for the beverage industry,” said Emerson's Ian Rubin, Director of Marketing - Mounted Bearings. “Properly designed bearings can deliver significantly greater equipment uptime and maintenance savings.”

New metric-bore CRES bearings

SealMaster CRES bearings are engineered for the food/beverage industry using various materials and patented sealing systems to extend life and optimize performance in corrosive conditions, while meeting CIP (Clean in Place) and SIP (Steam in Place) sanitation requirements. Part of the CRES series, the SealMaster PN Gold line now includes metric bore sizes for mounted ball bearings (20 to 60 mm) and “ER” cylindrical OD ball bearings (20 to 60 mm). Designed with brewery chemical and cleaning solutions in mind, they are equipped with patented multiple-lip seals and specialty coatings, and available with features like bolt-on end caps and backside shields that enable them to deliver industry-leading service life and performance. PN Gold bearings are engineered with high-phosphorous, electroless-nickel-plated inner and outer races, and multi-directional triple-lip seals. A unique zone-hardening process on the inner races hardens only the region under the ball path, resulting in improved lock reliability through less distortion at setscrew locations. The high-performance triple-lip contact seals provide multidirectional sealing to retain lubrication and exclude contaminants. Grease cavities in the seal assembly are factory filled with H1 Food Grade lubricant. A Tapered Land profile machined on the outer race redirects lubricant back into the raceway for improved lubricant circulation. An exclusive land-riding retainer design allows 360-degree grease circulation around the rolling elements for better grease retention and utilization.

Solid base housings on Sealmaster PN Gold bearings are machined from 316 stainless steel or high-strength composite with minimal gaps for fillings. Stainless steel bolt ferrules reinforce the bolt holes on composite bases for high load capacity and strength.

Other bearing styles in the CRES line include RPB-CR mounted tapered roller bearings in sizes 35 to 105 mm, and CR Gold mounted ball bearings with black-oxide-finished 52100 steel inner/outer races, 52100 rolling elements and single-lip rubber seals.

Stainless steel Rollway bearings

Rollway open and sealed stainless steel ball bearings are available in RS/2RS styles as standard, or in Z/ZZ styles on request. All metal components are stainless steel, including the backing ring used on the nitrile rubber seals. Rollway stainless steel ball bearings are ideal for general-purpose applications where there is moisture, water, steam and alkali exposure. Sealed bearings are pre-lubed with Shell Alvania RL, and special greases are available on request. The operating temperature range for 2RS models is -20 to 100°C.

System Plast mounted bearings for wash down

System Plast mounted bearings for the beverage industry are built with corrosion resistant composite housings of reinforced polyamide or antimicrobial Nolu-Clean®. A variety of popular housing styles are available, including pillow block, flanged, tapped base, hanger and take-up, in bore sizes 20-40 mm. The composite housings are a solid, smooth design to resist soil entrapment, with a stainless steel lubrication fitting. Both housings are available with 400-series stainless steel or 52100 bearing quality steel inserts, packed with H1 food-grade grease. Optional end caps and backside seals provide added protection for wash-down applications.
