Okuma spindle repair
Inspection, bearing replacement and run-in of Okuma spindles in our workshop.
Parts by brand
Okuma designs its own spindle, motor, encoder and OSP control, so every spare part has to match the exact build of the machine series. From our workshop near Bonn we source spindle units, bearing sets, drawbars and sensors for Okuma machines on the European market, check them before dispatch and ship them to you, with fitting in our workshop as an option.
Series and assemblies
The most common requests are for vertical machining centres of the MB-V series, horizontal MA-H and MB-H centres, LB lathes and Multus multitasking machines, which combine a turning spindle with a milling head. Bridge-type MCR machines and GENOS models are also part of the range.
On Okuma machining centres most of the load falls on the front bearing set and the drawbar; on LB lathes it is the main spindle bearings and the rotating chuck cylinder. On a Multus the turning spindle and the H1 milling head spindle are separate assemblies with their own part numbers, so we identify which one you need first.
New, reconditioned or exchange units for MB and MA machining centres and for the Multus milling head.
Matched sets of angular contact bearings in the same precision class, plus labyrinth and lip seals.
Drawbar, disc spring stack, collet and unclamping cylinder for Okuma milling spindles.
Spindle position and orientation sensors with connecting cables. We confirm compatibility from the marking on the old part.
How to order
Okuma marks its spindle units with its own drawing numbers, so a photo of the nameplate is the quickest way to the correct part.
Photograph the machine plate (model and serial number), the spindle or motor nameplate and, if possible, the label on the old part. The OSP control version helps as well.
We match the part number against documentation and the market: original or equivalent-quality new part, or a reconditioned unit.
You receive the options with prices. Availability and delivery time are confirmed after your enquiry and stated in the quote.
We inspect the part and ship it by courier or freight forwarder. On request we fit it in our workshop, with run-in and balancing.
Why us
We source parts across the European market, from original parts to proven equivalents.
Before dispatch we check runout, fits and completeness; spindle units are tested on the bench.
We fit bearings or a drawbar into your spindle and run it in with temperature monitoring.
Within the EU parts travel without customs paperwork; for other countries we help with export documents.

Repairing the original spindle is often the faster route compared with a new unit. Compare both options and we help you weigh them up.

FAQ
The spindle housing, or the cover next to it, usually carries a plate with the drawing number and serial number. If it is hidden, send us the machine plate: the serial number shows the machine configuration.
Units within one series differ in speed, taper and bearing arrangement. That is why we identify the part by number rather than by appearance.
That depends on the condition of the shaft and housing. After inspection we show you both options with prices, and you decide.
Yes. The springs are best replaced as a complete stack, together with a clamping force check, which we carry out in our workshop.
After installation the spindle orientation and drive parameters are checked. We tell you exactly what to check, and on-site support can be arranged on request.
Request
A photo of the machine plate and the spindle nameplate is enough for a first identification. We reply with options and ship the parts across Europe and worldwide.

Every operation below is done in our own workshop in Germany. Follow a link for what it involves and what we need from you.
Machine brand
We are independent and work with spindles of every builder. These are the makes whose spindles come across the bench most often.
