PN Gold Mounted CRES Ball Bearings Information

FEATURES AND BENEFITS

BEARING RACES The inner and outer ring of the Sealmaster PN Gold are a high phosphorous electroless nickel plated 52100 steel for exceptional corrosion resistance.

WIDE OUTER RACE Sealmaster has the industry’s widest outer race. The high phosphorous, electroless nickel outer race is 20 to 30% wider than industry standard outer races. This feature results in increased grease capacity, improved sealing options and increases the surface area for absorption of shock load. The outer race has a Tapered Land profile. The outer land surface in a conventional bearing is parallel to the axis of the inner ring. The Tapered Lands surface is tapered in a radial direction toward the bearing race. This subtle yet crucial design change ensures that lubricant will be easily redirected back to the raceway. With improved bearing lubricant circulation comes significantly longer bearing service life. This improved circulation and service life comes without any reductions in bearing radial or thrust capacities. For bearings that are maintained and relubricated on a regular basis, there is no significant difference in expected service life.

MULTIPLE LOCKING METHODS

SETSCREW LOCKING 300 series stainless steel 120° spaced, balanced three point contact minimizes inner ring distortion vibration, reduces noise, and improves reliability.

SKWEZLOC® CONCENTRIC LOCKING COLLAR SKWEZLOC is a concentric collar clamp design that results in near-perfect concentricity of the shaft to bearing bore and maintains near perfect ball path roundness, while reducing fretting corrosion. This design eliminates the shaft damage of setscrew locking, and minimizes bearing induced vibration for smoother quieter operation. The collar is fluoropolymer coated with an Endurion* coated TORX head cap screw that outlasts stripping 12 times longer than hex head cap screws.

HIGH PERFORMANCE SEAL (HPS) The triple lip contact seal design provides multi-directional sealing to minimize contamination ingress and retain lubrication – standard on all units. The 304 stainless steel shell and flingers protect from incoming contaminants and provide wear resistant contact surface to all three seal lips. The grease cavities in seal assembly are factory-filled with H1 Food Grade lubricant prior to shipment for additional contaminant resistance.

STAINLESS STEEL HOUSING High quality solid base designed investment cast passivated 316 stainless steel casting providing the highest amount corrosion resistance currently available for stainless steel housings. The investment cast process yields a smooth, easy to clean surface. The solid construction with machined base was designed for minimal gaps with no fillings.

COMPOSITE HOUSING High strength composite with reinforced stainless steel bolt ferrules for high load capacity and increased strength around the bolt holes. The solid construction with machined base was designed for minimal gaps with no fillings.

SPECIALIZED FOOD GRADE LUBRICATION The Sealmaster® PN Gold bearings are factory filled with Sealmaster GoldPlex-FG (Food Grade) grease (USDA H1 approved) which is suitable for mounted bearing lubrication where incidental contact with food products may occur in any application where clean, routine lubrication is required.

LOCK PIN AND DIMPLE The Sealmaster exclusive locking pin and dimple system provides a direct lubricant into the bearing cavity & ball path instead of around a lubrication groove, prevents outer ring rotation (sometimes referred to as “creep”), and allows ±2° static misalignment of the bearing insert

ZONE HARDENING INNER RACE Sealmaster incorporates a unique heat treat process that hardens the inner race only where it is needed…under the ball path. The high phosphorous electroless nickel plated 52100 steel, zone hardened inner race results improved lock reliability as a result of less distortion at setscrew location and improved thread conformity resulting in improved clamping and resistance to setscrew back-out.

LAND RIDING RETAINER The Sealmaster unique land riding metal retainer design provides superior pocket clearance that allows for 360° grease circulation around the rolling elements resulting in better retained and utilized lubrication. The land riding design of the retainer minimizes wear on both Ball and retainer, while maximizing stability, which is especially important in applications involving vibration, shock loading or high operating speeds.
