A national food and beverage company was
using standard mounted ball bearings on the
conveyors in their plant. The bearings were
exposed to extreme washdown conditions
and began to experience contamination
and lubrication issues that led to extended
downtime. During a failure analysis of the
bearings, it was determined that contamination
penetration was the root cause of their bearing
failures. There are a total of 248 bearings on this conveyor.
SEALMASTER® SOLUTION
Regal proposed to replace their bearings with
the Sealmaster® Reduced Maintenance PN
Gold™ solution. This enhanced bearing solution
addressed the contamination issue with the triple
lip multi-directional high-performance seal to
prevent contaminants from entering the bearing.
Regal also recommended a protective backside
shield that will prevent water from entering the
back raceways of the bearings during washdown.
The “sealed for life” bearing eliminated the
need for frequent lubrication intervals by the
maintenance staff.

Key Customer Need(s) and Benefits from Sealmaster® Products
Since implementation, the customer discovered
that where 14 bearings were previously needed
over the same time interval, 1 Sealmaster® Reduced
Maintenance PN Gold™ bearing proved to cover the
same performance life, saving the plant over $325,000
per year!
Sealmaster® Reduced Maintenance PN Gold™ Bearings
HIGH PERFORMANCE SEAL (HPS)
• Triple lip contact seal design provides multi-directional sealing to minimize contamination ingress and retain lubricant.
• Highly durable, FKM seal lip material provides good chemical resistance and can withstand high temperatures.
• 304 stainless steel shell protects bearing and components from incoming contaminants.
• 304 stainless steel rotating flinger provides a corrosion resistant wear surface for all three lips and shields seal from contamination.
PN GOLD™ BEARING WITH SKWEZLOC® LOCKING COLLAR
• SKWEZLOC locking collar centers the shaft in the bearing bore and secures the shaft with near perfect concentricity.
• Allows for quiet, smooth operation at higher speeds.
• Helps to protect shaft from scoring and burring.
• Helps reduce out-of- balance vibrational forces and fretting corrosion.
TAPERED LANDS
• Sealmaster® PN Gold™ Bearings have a wide outer race that features a tapered land profile.
• The tapered lands surface is tapered in radial direction toward the bearing race to ensure that lubricant will be easily redirected back to the raceway.
• Polypropylene material is resistant to corrosion.
• Hand-snaps into housing for easy installation.
• Shielded drain hole reduces moisture buildup.
