Bearings for Mining Equipment and Contaminated Environments

NSKNSK supplies high-quality bearings for contaminated and inadequately lubricated environments in the mining and aggregates industries.

The company's products enable clients to overcome unplanned downtime and resolve contamination and vibration issues in the industry.

Tough steel bearings for adverse mining conditions

NSK Tough Steel TF bearings are developed with innovative materials and heat treatment technology for improved performance under harsh conditions.

Bearings feature enhanced hardness, wear and seizure resistance, as well as an increased service life in contaminated or poorly lubricated environments.

TF bearings are also suitable for conveyors, slurry pumps, vibrating screens and crushers.

Ball and roller bearings

NSK's HPS™ Roller Bearings utilize the latest cage design features and specific surface treatments using state-of-the-art material, resulting in increased bearing load capacity and life expectancy.

The company provides a full line of both ball and roller bearings for heavy-duty mining applications, offering up to double the operating life and up to 20% higher limiting speeds.

Spherical bearings 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 industries.

Key features of the company's spherical 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

Pillow block housings for bearings

Manufactured from high-strength cast iron, pillow block housings are suitable for high-capacity spherical roller bearings or self-aligning ball bearings.

Key features include:

  • A variety of seal options for different contamination levels
  • 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 products and solutions aim to increase equipment reliability and quality, while reducing maintenance, increasing uptime and return on investment (ROI).

Asset Improvement Program for mining sites

NSK's Asset Improvement Program (AIP) offers an opportunity to unlock additional profitability through improved machine reliability and increased working knowledge.

The key to its success is the close working dialog NSK has with personnel to identify and understand the issues and problems that affect clients, as well as and their respective financial impact on their business.

The AIP Value Cycle is comprised of five stages:

  • Situational analysis
  • Value proposition
