Features & Benefits

Bearing Races

The inner and outer rings of the Sealmaster SS Gold™ are manufactured with 440c stainless steel. This provides exceptional corrosion resistance.

Wide Outer Race

Sealmaster stainless steel ball bearings offer the industry’s widest outer race. It comes standard with patented tapered-land bearing race profile that achieves increased grease capacity with improved sealing options. Additionally, the wider outer ring increases surface area for greater absorption of shock load.

The outer land surface in a conventional bearing is parallel to the axis of the inner ring. This is while the tapered-land surface is attenuated in a radial direction toward the bearing race. This subtle yet crucial design change ensures that lubricant will be efficiently redirected back to the raceway. Improved bearing lubricant circulation results in significantly longer bearing service life. Plus, this is achieved with no reduction in the bearing's radial or thrust capacities.

For bearings that are maintained and re-lubricated on a regular basis, there is no significant difference in expected service life.

Stainless Steel Housing

A high quality solid base is designed with passivated 316 stainless steel investment casting. This provides the highest amount of corrosion resistance currently available for stainless steel housings. The investment casting process yields a smooth, easy-to-clean surface. Solid construction with a machined base is designed for minimal gaps with no fillings.

High Performance Seal (HPS)

The triple-lip contact seal design provides multi-directional sealing to minimize contamination entry and retain lubrication. It comes standard on all units. The 304 stainless steel shell and flingers protect from incoming contaminants. They also provide a wear-resistant contact surface on all three seal lips. The grease cavities in the seal assembly are factory-filled with lubricant prior to shipment for additional contaminant protection.

 

 

Specialized Food Grade Lubrication

Sealmaster SS Gold™ bearings are factory-filled with USDA HI-approved grease. This is ideal for mounted bearing lubrication when incidental contact with food products may occur, or in any application where clean, routine lubrication is required.

Lock Pin and Dimple

Sealmaster™ products offer a locking pin and dimple system. This provides direct lubricant into the bearing cavity and ball path instead of around a lubrication groove. This prevents outer ring rotation, sometimes referred to as "creep." It also allows ±2° of static misalignment of the bearing insert.

Setscrew Locking

Using 300-series stainless steel with 120° balanced three-point contact minimizes vibration, reduces noise, and improves reliability. A precision-manufactured diamond faceted setscrew design contributes to improved clamping and resistance to backout.

Land Riding Retainer

The unique Sealmaster bearing land riding metal retainer design provides superior pocket clearance. This allows for 360° oil circulation around the rolling elements. This creates improved retention and use of lubrication.
