Sealmaster PN Gold Mounted Bearings Decrease Downtime
A large bakery experienced frequent bearing failures on their conveyors due to contamination from flour, water, and cleaning solutions. This resulted in significant downtime and maintenance costs, with bearings on the bun reversing conveyor being replaced 2-3 times a month.
The Problem
- Frequent bearing replacements: 26 times per year
- High maintenance costs: $30/hour labor + $600/hour lost production revenue
- Total replacement time: up to 2 hours per instance
The Solution
The bakery switched to Sealmaster™ PN Gold™ mounted ball bearings (p/n CRPS-PN23T), featuring a patented triple lip contact seal and Skwezloc® locking collar. This change brought about significant improvements:
Benefits
- Annual Savings: ~$33,000
- Reduced Downtime: Less frequent bearing replacements
- Lower Labor Costs: Fewer bearing removals and installations
- Improved Efficiency: Maintenance staff can focus on other priorities
- Simplified Inventory: Reduced need to stock multiple bearing brands
By upgrading to Sealmaster™ PN Gold™ bearings, the bakery achieved substantial cost savings and improved operational efficiency, making it a compelling solution for other industries facing similar challenges.
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.
- Quickly, easily installed, removed and/or repositioned.
- Helps to protect shaft from scoring and burring.
- Helps reduce out-of- balance vibrational forces and fretting corrosion.
Back Side Shields Available
- Nitrile rubber gaskets reduce bearing moisture contact.
- 304 stainless plates improve assembly strength.
- Drain slots reduce moisture buildup.
End Caps Available
- Polypropylene material is resistant to corrosion.
- Hand-snaps into housing for easy installation.
- Shielded drain hole reduces moisture buildup.
