Benefit from the technical support of our SERVICE engineers: research, recommendations, and/or support for your maintenance operations.


NTN Technical Assistance

At NTN, the service does not stop after the sale. To ensure our customers get the maximum service life out of their bearings, NTN provides after sales services and engineering support. NTN’s service engineers can help you reduce the cost of ownership of your machines:

  • guarantee the service life of bearings by supporting you in the assembly, disassembly and lubrication
  • maintenance performed correctly and within time limits while monitoring operations
  • preservation of the surrounding parts of the bearings


NTN's innovative TRIAGE Engineering Solutions powered by INSYNC Remote Diagnostics combines HI (Human Intelligence) with AR (Assisted Reality) to help keep production processes running optimally.

A cornerstone of the NTN UBE TRIAGE support system, NTN's INSYNC AR (Assisted Reality) has been designed to remotely connect NTN’s engineering bearing experts to front-line maintenance staff, safely and instantly around the clock, ensuring manufacturing facilities can extract great value from NTN’s bearing solutions now and in the future.

The state-of-the-art system allows NTN experts based at NTN’s Engineering Centre to send precise visual instructions remotely to maintenance technicians at any plant or manufacturing facility to ensure bearing maintenance issues can be fixed as quickly and efficiently as possible, minimizing downtime.

Preparatory analysis for technical assistance

To define the maintenance operation, equipment and the necessary staff, our NTN will analyze:

  • the type of bearing
  • how it is planned to be used
  • operating conditions
  • history and previous use

NTN's engineering support team may have to request additional engineering studies.
They may require access to move around your site in order to validate the preparatory analysis. The recommendations will be sent to you if necessary, for example if the existing configuration does not allow for the optimal functioning of the bearings.

Maintenance operations

NTN's engineering support team is present for the technical management of the work. They will guide the maintenance operators according to the established process and ensures good practices.

NTN can advise you on the assembly, disassembly and lubrication of the bearings.

Post-operative recommendations

At the end of the maintenance operation, NTN's engineering support team carries out a review.

They provide recommendations for maintenance, lubrication, and the maintenance tools to be used and the monitoring method for bearings when they are operating.

NTN performs audits of your mounting process and provides maintenance training to help increase your uptime.
