NTN’s Double Lip Seal Excels at Excluding Contamination
Welcome to our monthly newsletter! This edition shines a spotlight on the industry’s best deep groove ball bearing seal – NTN’s LLU double-lip seal. Let’s delve into why it’s the top choice for excluding contamination and retaining grease within bearings.
The Power of NTN’s LLU Seal: At NTN, we offer a diverse range of shield and seal types for our ball bearings, but none rival the effectiveness of our LLU double-lip seal. As shown in the picture below, this innovative orange seal boasts an inner lip pressed against the V-groove’s inner surface, while the outer lip creates a small gap with the inner ring, forming a labyrinth effect. Even if the inner lip wears, the contact pressure remains constant, ensuring prolonged bearing service life.
LLU Seal Success Stories: NTN’s LLU seal has generated significant cost savings and operational improvements across various industries. Here are just two examples:
- LLU Seal Success Story #1: A leading producer of potato chips faced frequent bearing failures on its seal checking line, costing over $25,920 annually. By switching to NTN’s LLU sealed ball bearings, bearing life doubled, and maintenance costs were significantly reduced, resulting in $26,964 in savings.
- LLU Seal Success Story #2: A prominent North American steel mill battled bearing failures on its cold rolling mill, incurring $33,000 per roll failure. With NTN’s LLU seal, downtime was reduced, uptime tripled, and annual savings surpassed $477,000.
