AUDIT of automotive bearing assembly lines

Doing an audit of your lines of automotive bearings with NTN-SNR decreases costs and increases the satisfaction of your customers.

Have you correctly installed your bearings? Benefit from the technical expertise of NTN-SNR in automotive bearings and mechanical sets to limit the risk of bad assembly on your production lines.

Preservation of your brand image

Mounting defects always have an impact on your brand image. Auditing your methods is a guarantee against premature wear related to a bad installation.

Gains in your mounting process

An adapted mounting operation is more efficient and therefore more economical. We therefore audit:

  • assembly lines for new products
  • already operating assembly lines

This second type of audit allows derivatives to be corrected which could have existed since the start, or have been installed over time.

Gains on your purchases of bearings

An incorrect installation causes premature failure of bearings. An audit of the assembly lines of automotive bearings can avoid warranty returns which generate repair costs: cost of dismantling, cost of bearings, fees to handle returned goods under guarantee.

Optimisation of the productivity of your assembly line

Guarantee your customers can enjoy the performance that you advertise. Well mounted bearings allow your assembly lines to operate optimally throughout their lifetime and to avoid sudden stops.

We can carry out 2 types of audits: audits of assembly lines for bearings and audits of production lines for ball bearings. We follow a rigorous method:

  • acknowledgement of your procedures to completely understand the context
  • audit of the line item by item (from the stage of receiving the bearings to the end of the operations related to the bearings)
  • review of your process, the methods used, state of the environment and cleanliness, the conditions for handling and transport
  • immediate notification of weak points that have been identified
  • final evaluation, taking into account every weak point
  • corrective recommendations regarding means and methods of assembly

We also support our clients in the implementation of recommendations as well as providing expertise in defective products.

During an audit of the assembly lines of bearings for gear boxes, we were guided towards a probable cause for improper mounting. We found a problem with the assembly technique that had a large impact at the level of the depression of the bearing ring. 
The result? There were flakes on the rollers, which led to premature destruction of the bearing in operation.

Our recommendations:

  • assemble under pressure and adapted equipment
  • measures to remove the sources of corrosion and pollution on the items

After having put these in place, the customer solved his problem. He now consults us when setting up any new products: we validate his equipment and its environment with him.
