Introduction
A customer experiened repeated bearing failures in conveyor rollers. They were changing approximately 36 bearings annually and failures were taking place about every 6 week. Investigations by NSK showed the failures were caused by the ingress of water and hard particulates. NSK recommended replacing the standard bearings with NSK Molded-Oil bearings. A test of the bearings was conducted and no failures have occurred in 2 years. This solution resulted in a significant cost savings.
- NSK Molded-Oil Bearings
Key Facts
- Approx. 26 bearing failures annually
- Significant number of man hours needed to replace failed bearings
- Substantial machine down time leading to costly loss of production
- NSK solution, Molded-Oil ball bearings
- Productivity improvement
- Cost saving realized
Value Proposals
- NSK Application Review determined the bearings had failed due to the absence of lubrication and ingress of water and hard particulates
- Having completed the review NSK recommended the use of Molded-Oil ball bearings
- A trial using Molded-Oil ball bearings was implemented
- The trial resulted in a substantial increase in bearing life and reduction of machine down time.
Product Features
- Molded-Oil provides continuous supply of lubrication oil
- 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
- Molded-Oil provides a continuous supply of lubricant achieving extended maintenance-free performance. Also available for high speed applications
- Available in ball bearing, spherical roller bearing and tapered roller bearings types
- Stainless steel for corrosive environments.
