Increasing Uptime and Reducing Costs for Mine and Quarry Operations
4200 Goss Road, Ann Arbor, MI 48105, United States of America
For more than 100 years, NSK has been a global pioneer in bearing technology and manufacturing, with particular specialization in mine and quarry applications.
NSK field engineers and technicians have worked with facility operators for decades, analyzing the challenges and creating process-specific, condition-proven bearing solutions that deliver exponentially greater production uptime, extended maintenance intervals, and consistently lower operating costs.
For applications where contamination, shock and vibration loads, and poor lubrication can compromise output, NSK bearing solutions have dramatically reduced planned and unplanned maintenance downtime for the most respected producers in the industry.
NSK Tough Steel TF bearings are developed with innovative materials and heat treatment technology for improved performance under harsh conditions. Tough Steel bearings feature enhanced hardness, wear and seizure resistance, and deliver increased service life in contaminated and poorly lubricated environments. TF bearings are also suitable for conveyors, slurry pumps, vibrating screens and crushers.
NSK’s newly designed spherical roller bearings with detachable seals provide a first in the industry. The bearings come with a removable high-performance seal which allows for proper installation via clearance measurement in tapered bore applications. This new design comes standard in NSK’s Tough Steel to allow for increased load ratings while still maintaining ISO envelope dimensions.
NSK’s Long-Life HPS™ spherical roller bearings for vibrating equipment are engineered specifically to contend with high speeds, shock loading, misalignment, marginal lubrication and frequent vibration of equipment used in mining, aggregate, cement and construction applications. Key features of these bearings include:
Manufactured from high-strength cast iron, NSK pillow block housings are engineered to deliver optimal performance and productivity from high-capacity spherical roller bearings or self-aligning ball bearings. NSK’s unique OLB seals provide optimum protection against contamination without some of the limitations of conventional seals.
Key features include:
NSK’s Asset Improvement Program (AIP) provides mine and quarry operators the ability to unlock additional profitability, through improved machine reliability and optimized stores management. The key to its success is the close working dialog NSK enjoys with key mine personnel, to identify and understand the challenges these clients face, and their respective financial impact on their business.
The AIP Value Cycle is comprised of five stages:
By working with NSK, mine operators around the globe have realized significant – and consistent – improvements in machine output, uptime, and cost reductions.
Heavy contamination in a coal mining head pulley was causing bearing failures every 18 months leading to lost production and increased maintenance time. NSK Tough Steel bearings were installed and extended the bearing life to over six years.
Rather in the raw or finishing mill, cement vertical roller mills are used to grind the raw cement materials to fine particles. The quality of the cement is dependent on the size of the materials.
NSK's Long-Life Spherical Roller Bearings for vibrating equipment are engineered specifically to contend with high-speeds, shock loading, misalignment, marginal lubrication and frequent vibration of equipment used in mining, aggregate, cement and construction industries.
Typical bearing failures: Most bearings don't reach their full L10 calculated life. NSK's Tough Steel family of bearings addresses the root causes of over 80% of bearing failures seen in their failure analysis labs: marginal lubrication and contamination.
Worldwide, NSK is the acknowledged leader in advanced motion and control technology, rapidly driving major developments in materials, mechanical design, lubrication and sealing to downsize bearings and reduce costs without compromising machine performance.
The reliability and specific properties of bearing components such as rings, rolling elements and cages are largely determined by the materials used.
NSK engineers proposed a complete bearing assembly be designed such that the resultant unit could simply be bolted down to the machine frame without complex assembly of bearings, seals and lubrication.
