NSK Bearings for Mining Equipment and Contaminated Environments
NSK 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
- Value implementation
- Value measurement
- Share best practices

Bearings for Conveyor Applications
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.
Bearings for Pulverizers and Vertical Rolling Mills
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.
Spherical Roller Bearings for Vibrating Equipment
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.
Tough Steel Bearings for Extended Life in Heavy Industry
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.
White Papers
NSK Vibrating Screen Success Story
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.
Predicting Bearing Life
Calculating the basic fatigue life expectancy of roller bearings.
Bearing Material Selection
The reliability and specific properties of bearing components such as rings, rolling elements and cages are largely determined by the materials used.
