Nachi Sealed Deep Groove Ball Bearings

Advanced seal design provides excellent protection and smooth operation. The combination of a unique lip design and seal groove provides a labyrinth and steady seal contact. Breathing mechanism avoids torque increases caused by internal pressure variation due to changes in operating temperatures. NSE seals allow NACHI bearings to have constant smooth operation and long service life.

Featuring the following benefits: 

• Triple seal lips
• U-shape seal groove
• Breathing mechanism (on seal O.D.)
• Non-breather type seals are available for applications in severe water contact environments
• Superior in sealing out dust, dirt and contamination
• Superb grease retention
• Light torque
• Rivet-type pressed steel cages for strength and durability
• High-performance grease for long life and low noise
 

SUCCESS STORY: NACHI Sealed Deep Groove Ball Bearings Increased Uptime for Packaging Manufacturer

Problem: A Styrofoam packaging manufacturer needed an improved solution for failing bushings on a molding machine. The life of the bushings was 12 to 16 months. The NACHI solution had the potential to resolve downtime frequencies nationwide.

Solution: By working closely with the end-user, the underlying causes of the bushing failures were diagnosed and equipment was redesigned to incorporate a sealed deep groove ball bearing. NACHI provided in-depth calculations to demonstrate how the bearings were able to exceed the application requirements with over 25 times longer life. NACHI successfully decreased downtime frequencies and the manufacturer has modified their molding machines to incorporate the design changes.
