Text version of the page

9 High Performance Seal (HPS) • Sealmaster HPS seal design provides multi directional sealing for proven performance in contaminated environments. • 304 stainless steel shell protects from incoming contaminants and provides a wear resistant contact surface for all three seal lips. • Stainless steel, rotating flinger directs contaminants away from the bearing. • Highly durable, FKM seal lip material provides chemical resistance and withstands high temperatures. CRES Seals ™ • High phosphorous, electroless nickel plated 52100 steel races for exceptional corrosion resistance (see chart at right) • Zone hardened inner races for longer life and quieter operation • Unique metal land riding retainer allows 360° grease flow around rolling element for improved lubrication circulation. • Two locking options: - ERX CRES Skwezloc Collars feature a fluoropolymer rich surface coat on a molecular binder layer which provides excellent corrosion resistance, abrasion durability, anti-peeling, and non-stick properties. - ERX CRES setscrews are manufactured with 300 series stainless steel material. Positioned at 120° apart, the Sealmaster setscrews provide a balanced 3-point contact. 5% Salt Fog Test Results (144 Hours) Area Rusted % Time in Hours 0 5 10 15 20 25 30 35 24 48 100 144 PN Gold Zinc Coated Thin Dense Chrome Coated 440C Stainless Steel Nickel Teflon® Coated Bearing Salt Fog Results (144 hours) Tested per ASTM B117, a salt fog test is performed by placing bearing parts in a salt fog chamber. The chamber is filled with a highly corrosive, salt solution and heated to 100°F. After 144 hours, the parts are removed and results are compared. See photos below.
