Repair of spindles and motor spindles fitted with NSK bearings
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnosis of spindles and motor spindles fitted with NSK Ltd bearings — one of the world's largest bearing manufacturers and a benchmark for high-precision machine tool spindle mountings.
NSK Ltd, a Japanese bearing giant since 1916
TLDR: NSK Ltd (Nippon Seikō Kabushiki-gaisha, Tokyo, founded 1916) is one of the world's largest bearing manufacturers. Its range covers industrial, automotive and precision bearings, including NSK spindle bearings widely fitted to high-precision machine tools.
NSK Ltd, founded in 1916 in Tokyo, is one of the world's largest bearing manufacturers, present across industrial machinery bearings, automotive components and precision machinery and parts. The group has established itself as a reference supplier for the precision bearings used in machine tool spindles, alongside FAG (Schaeffler) and SKF. These bearings equip the main spindle mountings of a great many machines, delivering the rotational accuracy and stiffness that high-precision machining demands.
Two different companies carry the NSK initials. NSK Ltd makes bearings. Nakanishi Inc., also Japanese, sells its dental and industrial spindles under the NSK brand — a homonym, not a subsidiary. The confusion is common when ordering a part. If your equipment is a spindle sold under the NSK brand, our Nakanishi page is the one you want; if you are after the bearing inside your spindle, you are in the right place.
One further distinction: NSK Ltd does not manufacture spindles. A spindle fitted with NSK bearings remains a spindle from its own builder. For the role of the component, see our page on spindle bearings.
A range of high-precision spindle bearings for high-speed machining
TLDR: NSK spindle bearings cover several configurations depending on the application — angular contact ball, hybrid ceramic ball — in high precision classes matched to the demands of high-speed machining.
NSK spindle bearings are designed for the precision and stiffness demands of modern spindles: angular contact ball configurations for combined radial and axial loads, and hybrid ceramic ball versions for very high speed, where reducing the mass of the rolling elements limits heat generation and centrifugal force.
Selection rests on several technical criteria: precision class (ABEC or ISO equivalent), internal clearance, lubrication method — grease or air-oil — and compatibility with the maximum speed the application targets. Two NSK bearings of the same dimensions are therefore not interchangeable for that reason alone.
Spindles and motor spindles fitted with NSK bearings we cover (non-exhaustive)
- Machine tool main spindles fitted with NSK angular contact bearings
- NSK motor spindle bearings, hybrid ceramic, for high-speed applications
- Precision bearings for grinding spindle mountings
- Rotary table and precision axis bearings, all brands
- NSK bearings integrated into third-party spindles
Interfaces and specifications
The NSK spindle bearings we use in our repairs cover angular contact and hybrid ceramic configurations — exact references selected according to the original specification of your equipment.
NSK motor spindle bearings with ceramic balls are the ones we see most often on high-speed machining applications. An NSK spindle bearing is never picked from a catalogue: the original specification, the service speed and the lubrication method determine the reference.
Our expertise on spindles and motor spindles fitted with NSK bearings
TLDR: Brochexpress works across the whole life cycle of your spindles fitted with NSK bearings, with the same rigour as on every other component in our portfolio.
On-site customer service
- Diagnosis and intervention directly on your machine, in your production workshop, to limit downtime caused by spindle bearing wear.
Full diagnosis
- Checks on clearances, balancing, the condition of the angular contact bearings and lubrication, with a detailed technical report.
Preventive and corrective maintenance
- A maintenance programme matched to your production rate, with preventive bearing replacement ahead of full failure, plus corrective work when a breakdown occurs.
Overhaul and refurbishment
- Bearings replaced with NSK references equivalent to or above the original, seals renewed and a rotation test in the workshop, restoring the builder's original tolerances.

Frequently asked questions
Are NSK the bearing maker and NSK the dental spindle brand the same company?
No, and the confusion is common. NSK Ltd (Nippon Seikō, Tokyo, 1916) makes bearings. Nakanishi Inc. sells dental and industrial spindles under the NSK brand. Two separate companies, two different products — we work on both, through two separate pages.
Do you work on spindles fitted with NSK hybrid ceramic ball bearings?
Yes. We diagnose and repair these spindles, taking their specific speed and lubrication requirements into account.
What is the average lead time for an NSK spindle bearing replacement?
Allow around 20 working days in the workshop, depending on the condition of the spindle and the availability of the references.
Do you always use NSK bearings for your repairs?
No. We select the bearings best suited to each spindle according to its original specification — NSK is one option among others, alongside FAG, SKF and GAMET.
Do you offer a preventive maintenance contract covering scheduled bearing replacement?
Yes, we set up preventive maintenance programmes matched to your production rate.
A reliable partner for your industrial performance
Whether it is an emergency callout, a full workshop overhaul or a preventive maintenance programme, Brochexpress puts its expertise at the service of your production. As an independent workshop, we work on spindles and motor spindles fitted with NSK bearings, whatever the machine brand.
Our teams are available from our sites in Beaurepaire (France) and Lussery-Villars (Switzerland) for a needs assessment, a diagnosis or a tailored quotation.
