Multi-market maintenance kit : Facilitating maintenance to improve productivity

In harsh industrial environments – mining, steel, metallurgy, water treatment, sawmills and paper mills – equipment reliability and maintenance are essential. A breakdown can halt production, incur high costs and compromise deadlines. Preventive and effective maintenance of components, particularly bearings, therefore becomes a strategic issue.

The challenges of maintenance in harsh environments

Equipment such as crushers, conveyors, screens and loaders are subject to extreme conditions: heavy loads, shocks, humidity, dust and temperature variations. In this context, maintenance aims to:
-    Avoid premature wear of critical components
-    Reduce recurring breakdowns and unplanned downtime
-    Control maintenance costs
-    Ensure consistent performance despite environmental constraints
Aware of these challenges, NTN Europe offers simple, effective and reliable maintenance solutions, particularly for its spherical roller bearings. 

Multi-market maintenance kits  : all-in-one, simple and effective

To simplify the lives of maintenance professionals, NTN Europe offers two  maintenance kits designed to facilitate maintenance, bearing assembly and prevent equipment failure. 

1-    Partial maintenance kit (without bearing replacement):
The kit includes a sealed spherical roller bearing (SRB)  , a mounting sleeve, 2 retaining rings, 2 sets of nitrile seals, and 1 technical manual. 

Benefits: 

• Bearing life increased by a factor of 3 thanks to reinforced sealing. 
• Simplified maintenance: all components in a single kit.  
• Fewer interventions: high-performance sealed bearing and reduced re-greasing. 
• Environmentally friendly: reduced waste and grease consumption. 

2-    Complete maintenance kit (with bearing replacement)
The kit includes: 1 SNC bearing (in 2 parts), 1 bearing (standard or sealed), 1 mounting sleeve, 2 retaining rings, 2 sets of nitrile seals, 1 plug, 1 technical manual. 

Additional benefits: 

• Simplified logistics management: a single box ready for use
• Time saving: reduced risk of error during assembly
• Optimised maintenance: a single kit for two applications 
• Reduction in production downtime and unexpected breakdowns

Frequently asked questions about the maintenance of spherical roller bearings  – Answers from Pierre Hingrez – market expert at NTN Europe

Why did you introduce the SRB all-in-one kits?  
To meet the needs of manufacturers who need to respond quickly and efficiently in the event of a breakdown or during scheduled maintenance. The kits ensure safe installation, simplified logistics and reduced human error, while optimising bearing service life.

Who are they for?
All maintenance professionals working in harsh environments: technicians, maintenance managers, methods offices and machine fleet managers in the heavy industry, agri-food and infrastructure sectors.

How can you quickly replace a spherical roller bearing  in the event of a breakdown? 
Thanks to NTN SRB kits, all the components needed for replacement are available in a single package. Clear instructions facilitate assembly, and the components are designed to fit directly into existing configurations (fixed or floating mounting). Replacement can be carried out on site in a minimum of time, significantly reducing machine downtime.

In general, what advice can you give for bearing maintenance? 

• Choose sealed bearings for aggressive environments
• Use all-in-one kits to avoid omissions or assembly errors
• Follow the assembly recommendations (alignment, tightening torque, lubrication)
• Regularly monitor temperature, noise and vibrations
• Plan regular maintenance to prevent breakdowns. 

NTN Europe's maintenance kits are much more than just practical solutions: they are a real lever for optimisation for industrial maintenance services. By facilitating maintenance, reducing breakdowns and extending the service life of equipment, they actively contribute to improving the overall performance of production sites.
