Part #:711237
Catalog #:CRFBF-PN31
KEY FEATURES
- High phosphorous electroless nickel plated 52100 steel for exceptional corrosion resistance
- High performance triple lip contact seal design provides multi-directional sealing with 304 stainless steel body and flinger to minimize contamination ingress and retain lubrication
- Fluoropolymer coated cast iron housing for corrosion resistance.
- USDA H1 complaint food grade grease
- Exclusive locking pin and dimple system provides a direct lubricant into the bearing cavity and ball path instead of around a lubrication groove, prevents outer ring rotation.
- Unique land riding retainer design provides superior pocket clearance that allows for 360° grease circulation around the rolling elements resulting in better retained and utilized lubrication.
- Tapered Lands ensures that lubricant will be easily redirected back to the raceway.
