Find bearings by mounting position
NSK bearings sorted by where they sit in the machine.
Start from the position, not the size. Spindle front, spindle rear, ball screw support and general equipment shafts each call for a different NSK execution, and we match the reference to that location.

Matched sets and preload
Matched set and preload arrangement confirmed before dispatch.
Precision spindles and feed axes run as bearing sets. Replacing one bearing without the right pairing can cost you runout or positioning accuracy, so we confirm the set, the arrangement and the preload against your machine first.
- Back-to-back, face-to-face and tandem arrangements checked against the spindle drawing or old set
- Speed, preload and lubrication asked before the NSK series is confirmed
- Super-precision and machine tool series bought on one order
Matched set and preload arrangement confirmed against your spindle before dispatch, so the rebuild goes in as one correctly paired set.

What spindle, CNC and precision machinery buyers say.
Feedback from buyers on correct executions, genuine NSK packaging and identifying references from old bearing markings.
Our spindle rebuild shop depends on NSK super-precision bearings from jpnsk.com. They confirm the matching set and preload arrangement before dispatch, and every spindle we have rebuilt has met the runout specification.
We needed NSK ball screw support bearings for a CNC axis retrofit. The supplier provided the correct execution and measurement report, and our engineer verified the fit on arrival. The axis holds position to tolerance.
When a high-speed spindle failed, they identified the correct NSK precision reference from the old bearing markings the same day. The replacement arrived within the week and the machine is back in production.
Pricing on a set of NSK angular contact bearings for a machine tool rebuild was competitive, with genuine NSK packaging and full documentation. Our quality inspection passed on first sample.
As a precision machinery maintenance buyer, I value suppliers who do not guess. They asked about speed, preload and lubrication before confirming the NSK series. That discipline has kept our machine downtime low.
The NSK cylindrical roller bearings for our high-speed spindle build were supplied to the exact tolerance class. The internal clearance verified against the measurement report, and the spindle has run at design speed without issues.
FAQ
NSK bearing enquiries: common questions.
What should my NSK bearing enquiry include?
Include the machine model, the complete NSK part number with suffix, the bearing position, any sleeve or housing number, quantities, destination country and postcode, and your required arrival date. This lets us confirm the exact execution in one pass.
My repair list only has a short stock code. Can you still quote?
Yes, once the missing details are filled in. A short code hides the seal and clearance, so we confirm the exact structure with you before quoting. Any technical change needs your approval.
Can you confirm the bearing from photos of the markings?
Yes. Send clear photos of the ring face markings on WhatsApp or by email and we help identify the correct NSK precision reference. Add the machine model and position for a faster match.
What does the written quote state?
The written quote states part number, quantity, price and currency, stock status, estimated lead time, validity and the applicable shipping or tax terms. It also lists the product documents supplied with the order.
