Maximize Mining Equipment Uptime with NSK's Advanced Bearing Solutions
Durability and reliability are crucial for mining machinery in remote locations, where a single component failure can halt operations. Bearings in mining, quarrying, and construction endure punishing loads, misalignment, mechanical shock, grit, contamination, and marginal lubrication. Access to machinery used for extraction, transport, and processing is often remote or restricted, making unexpected failures costly and disruptive.

NSK Spherical Roller Bearings for Vibrating Equipment
NSK’s long-life VE/VS series spherical roller bearings are engineered specifically to handle high speeds, eccentric loads, and mechanical shock in vibrating machinery. With an optimized internal bearing design and tightly controlled clearance and dimensional tolerances, these bearings deliver robust capacity and smooth operation over an extended service life.
Engineered Solutions for Vibrating Equipment:
- Manufactured from ultra-clean steel for optimal fatigue strength and longer life
- Heavy-duty, precision machined one-piece brass cage
- Advanced raceway surface finishing for durability and wear resistance
- Special dimensional tolerances - set at 1/2 relative to the normal - to minimize vibration during operation
- Special internal clearance - set at upper 2/3 relative to the standard - for optimal operating clearance and reduced heat generation
Performance Benefits:
- As much as twice the service life of conventional bearings in applications subject to frequent vibration
- High resistance to heavy and shock loads
- Surface finish minimizes sliding contact in high load zones and facilitates better lubricant film
- Superior roller guidance and lubricant distribution from machined brass cage
- High-speed performance with low temperature rise
- Reduced bearing damage from slippage, surface fatigue and flaking
- Higher operational reliability - reduced maintenance cost

Contaminant and Wear Resistant: Sealed Spherical Roller Bearings
The harsh conditions of mining and quarrying operations take a toll on conventional roller bearings used in head, tail, drive, and tensioning pulleys of conveyors. These bearings often suffer from contamination by hard particles like dirt and dust, as well as water ingress, leading to significantly shortened lifespans. The result? Costly downtime, repetitive maintenance, and thousands of dollars lost.
Spherical Roller Bearings with Removable Seals are engineered to tackle mining's toughest challenges. These complementary solutions combine advanced materials with innovative sealing technology to maximize conveyor reliability while minimizing maintenance costs.
Comprehensive Sealing Solutions:
- High performance seal design, including characteristics to compensate for bearing misalignment
- Removable seal permits measurement of internal clearance during installation
- Easy, bolt-fastened installation of seal
- Dimensionally interchangeable
High Performance Material:
- NSK has adopted our Hi-TF long-life Tough Steel material for bearing inner and outer rings, with the technology to:
- Exponentially have a longer service life in contaminated lubrication conditions.
- Reduce the rate of wear and improve seizure resistance.
- Offer organically higher attainable dynamic loads.
Performance Advantages:
- Combining the Tough Steel material technology with advanced and easy-to-install seals, NSK delivers:
- High performance against contaminant-related bearing failures.
- Reliable solutions for conveyor applications.
