NSK Increasing Uptime and Reducing Costs for Mine and Quarry Operations

NSK

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.

For Adverse Mining Conditions, NSK Gets Tough

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.

Added Protection, Same Footprint: NSK Spherical Roller Bearings with Detachable Seal

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.

Extended Uptime for Vibrating Equipment

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:

  • Heavy-duty brass cage
  • Optimized cage geometry for improved lubrication and reduced roller skew
  • Tighter clearance and dimensional tolerances
  • Improved raceway finish and geometry for lower heat generation

Maximum Bearing Performance: NSK Pillow Block Housings with OLB Seals

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:

  • OLB seals do not require grease or maintenance to operate
  • OLB seals 2 piece design keeps contamination out and lubrication in
  • Housings available in cast iron or ductile steel
  • Temperature strip to easily detect heat issues
  • Oil lube options
  • Options for vibration and temperature sensors
  • Auto lube or other custom ports available

NSK’s Asset Improvement Program for Mine Operators

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:

  • Situational analysis
  • Value proposition
  • Value implementation
  • Value measurement
  • Share best practices

By working with NSK, mine operators around the globe have realized significant – and consistent – improvements in machine output, uptime, and cost reductions.
