Machine rebuild and repair
- Buy by complete NSK model, not by size alone.
- Keep the exact specification the equipment or repair requires.
- Enquire by single model, matched set or equipment parts list.
Find bearings by equipment and work order. Feed Mechanisms Company quotes each line by complete NSK model and shaft position, for buyers worldwide.

Spindle, feed axis and auxiliary drive bearings do different jobs, even on one machine. List function, preload, precision and arrangement by position, and the quote matches what the equipment requires.
| State in the enquiry | SpindleAngular contact, cylindrical roller, matched sets | Feed axisBall screw support bearings | Auxiliary driveDeep groove and thrust bearings |
|---|---|---|---|
| Function | Identify the line as a spindle bearing and name the machine. | Identify the feed axis or linear axis the bearing supports. | Identify the auxiliary drive or the defined axial support position. |
| Preload | State the preload required for the bearing or set. | State the preload given in the axis specification. | State it where the equipment specification calls for it. |
| Precision | State the precision class from the spindle specification. | State the precision class and the drawing version. | Keep the complete NSK model from the parts list. |
| Arrangement | State the matched arrangement of the set. | State the arrangement if bearings are ordered as a set. | List the quantity for each position alongside the main parts. |
Repair work holds to the exact NSK specification. Retrofit and new-build projects add a drawing version, and any engineering change is reviewed on its own.
Function, arrangement and revision control each sit with a different person. The quote should serve all three.
Sets the axis function and the approved bearing specification.
Sets the bearing set arrangement and the repair requirements.
Tracks drawing versions and separately quoted alternatives.
Machine tool rebuild
Pricing on a set of NSK super-precision bearings for a machine tool rebuild was competitive. The bearings arrived with the correct packaging and documentation, and our quality inspection passed on first sample.
Park Sang-hoPark Precision Machine, South Korea
CNC grinding
We had an urgent spindle bearing failure on a CNC grinder. The supplier identified the correct NSK precision reference, shipped same-day, and the spindle was rebuilt and back in production within the week.
Michael ChenChen Precision Grinding, USA (CA)
Linear axis retrofit
We needed NSK ball screw support bearings for a linear axis retrofit. The supplier provided the correct execution, and our engineer measured the fit on arrival. The axis now holds position to the tolerance we specified.

Short answers for engineers, service leads and project buyers sourcing NSK bearings.
They differ by bearing function and product family. A spindle line usually covers super-precision angular contact or cylindrical roller bearings, often with a matched arrangement and required preload. A feed-axis line covers ball screw support bearings. List them separately, even when they belong to one machine.
Provide the exact specification, the complete assembly, and whether a separately marked alternative is acceptable. Function, preload, precision and drawing version give the comparison its basis. Any technical change requires your approval.
State the new version so the affected lines can be checked against it. A resulting engineering change is reviewed separately and is not treated as a routine substitution. It goes ahead only with your approval.
Yes. Send a clear photo of the marking and note the items still to be confirmed. The specification is settled before you accept the quotation.
