SealMaster PN Gold Food and Beverage Bearings

Food and beverage manufacturing has a particular challenge other industries don't face. To keep food safe from bacteria growth, equipment needs regular cleaning. Washdown procedures, involving high-pressure spray and chemical cleaning agents can damage equipment.

Manufacturers often worry about corrosion of housing and bearing materials. Another concern is the ingression of the moisture into the bearings themselves.

Bearings Made to Resist Corrosion

SealMaster PN Gold series ball bearings meet the challenging demands of food and beverage applications. The PN Gold series offers several different housing materials, including:

• 316 passivated stainless castings;
• high-strength composite material; and
• fluoropolymer-coated cast iron material.

All three of these materials provide excellent protection against corrosion.

But corrosion-resistant housings are only the first step in corrosion resistance. SealMaster PN Gold bearings feature a unique bearing insert. A high phosphorous, electroless nickel-plated 52100 steel material makes up the inner and outer rings. This plating process provides exceptional corrosion resistance. The insert also uses rolling element balls that are made of 440C stainless steel.

The unique land riding, corrosion resistant composite retainer provides superior pocket clearance. This allows for better lubrication around the rolling elements.

Besides corrosion-resistance, the insert is also equipped with the HPS sealing system. This is a triple lip seal that offers multi-directional sealing. This sealing minimizes contamination ingression and retained lubrication. A two-piece stainless-steel shell and flingers surround the lip seal. All this adds to the seal effectiveness while providing a smooth surface for the seal lips to ride.
