§ Find the type by position
Which NSK bearing type fits each machine position?
Each machine position needs a different bearing type. Spindles use super-precision angular contact sets, feed axes use ball screw support bearings, and larger rotating assemblies use spherical roller bearings. Start from the position, then send us the full reference so we can confirm it.
| Machine position | NSK bearing type | Link |
|---|---|---|
| Spindle | Super-precision angular contact ball bearingsMatched sets for spindle arrangements, where preload and precision class set runout. | View angular contact → |
| High-rigidity positions | Cylindrical roller bearingsFor high-speed, high-rigidity locations where internal clearance and tolerance class matter. | View cylindrical roller → |
| Feed axis & ball screw support | Ball screw support bearingsFor feed mechanisms and linear axes. Correct execution decides whether the axis holds position. | View feed axis bearings → |
| Large rotating assemblies | Spherical roller bearingsFor larger rotating assemblies. Confirm the adapter sleeve or housing reference along with the bearing. | View spherical roller → |
| Specified positions | Self-aligning ball bearings & thrust bearingsSupplied where the machine specification calls for them. Also view thrust ball bearings. | View self-aligning → |
General bearings in the same machine are also supplied: deep groove ball bearings (open, shielded or sealed as specified) and angular contact ball bearings for combined loads.

§ One order, one machine
Super-precision and general NSK bearings in one order
You can buy the super-precision spindle sets and the general bearings for the same machine in one order. NSK Bearings: Source Factory Direct Sales supplies NSK super-precision and machine tool series together with the deep groove, angular contact and roller bearings used elsewhere in the machine.
- Spindle sets with the matched set and preload confirmed before dispatch.
- Ball screw support bearings for the feed axes of the same machine.
- General bearings with the specified open, shielded or sealed execution.
- One direct contact for repair quantities, maintenance lists and long-term spares.
§ Identification before quotation
We confirm the bearing before we quote it
Before we quote, we fill in any missing identification details in three steps. This stops wrong executions, mixed drive-end and non-drive-end quantities, and incomplete assemblies before they are ordered.
-
Step 01
Confirm the exact execution
We check the full brand suffix (seal, clearance, cage, arrangement, precision class) against your machine data, not just the bore and outside diameter.
-
Step 02
Check the assembly is complete
We go through each position, matched set and adapter sleeve or housing so the quote covers the whole replacement assembly.
-
Step 03
Mark possible alternatives
If an alternative could be considered, it appears as its own clearly marked line. It never quietly replaces the reference you asked for.
Any technical change requires buyer approval
