Success Story
Industry: Food & Beverage
Application: Conveyor Belt
Cost Savings: $10,159
Introduction
A vegetable-processing company was experiencing repeated ball bearing failures on their transport systems. NSK was asked to investigate the problem and offer a solution. It was determined that a large amount of water was entering the bearings and washing out valuable grease. NSK suggested the use of sealed, corrosion-resistant Molded-Oil Bearings. This solution allowed grease to remain in the bearings and increase bearing life.
- Conveyor Belt
- Molded-Oil Bearings
Key Facts
- Conveyor belt
- Vegetable processing
- Frequent bearings failures
- Service life of only 2 weeks
- Increased service life required
- NSK solution: Molded-Oil Bearings
- Result: Bearing lifetime increased from 2 weeks to over 9 months
Value Proposals
- The investigation carried out by NSK revealed that severe water ingress was causing problems (grease being washed out of the bearings)
- Use of corrosion-resistant Molded-Oil bearings
- Service life was significantly increased
- Cost saving realised
Product Features
- Molded-Oil provides continuous lubrication supply
- Stainless steel for corrosive environments
- Grease-free property with no oil refilling keeps operating environments clean
- Operating life more than twice as long as grease lubrication (in water or dust contaminated environments)
- Contact-seal type available in standard inventory for ball bearings
- Extended maintenance-free performance is acheived as Molded-Oil provides a continuous supply of lubricant.
- Available for high speed applications
- Available in ball bearing, spherical roller bearing and tapered roller bearings types
