Success Story
Industry: Steel & Metals
Application: Wire guides
Cost Savings: € 10 000
Introduction
A wire manufacturer in France was experiencing frequent damage on final products due to bearing failures within their wire guides where Deep Groove Ball Bearings were mounted. On average, the bearings failed every 6 weeks, incurring maintenance time and loss of production. The bearings were failing due to ingress of contamination behind the seals and NSK recommended to replace the existing bearings with Stainless Steel Deep Groove Ball Bearings with Molded-Oil lubrication and DDU seals.
- Wire guides
- Deep Groove Ball Bearings with Molded-Oil
Key Facts
- Wire manufacturing - Wire guides
- Bearing replacement every 6 weeks
- Contaminated environment
- NSK solution: Stainless Steel Deep Groove Ball Bearings with Molded-Oil and DDU seals
- Bearing replacement reduced to 3 times per year
Value Proposals
- The customer experienced many failures on their wire guides. An Application Review determined that ingress of contaminants from the production process was the main cause of failure
- The existing 2RS sealed Deep Groove Ball Bearings were inadequate
- NSK recommended Stainless Steel Molded-Oil Deep Groove Ball Bearings with DDU seals
- Since the introduction of new bearings, lifetime and machine performance has been significantly improved
