Shop by shaft position

Each shaft position does a different job. Buy NSK bearings to match it.

Feed Mechanisms Company supplies NSK bearings for spindles, feed axes and auxiliary drives to buyers worldwide, so every line can be separated by function.

Spindle

Sets running accuracy at the tool, so arrangement, preload and precision class define the right bearing.

Super-precision angular contact ball bearings, cylindrical roller bearings, matched sets

Feed Axis

Holds the ball screw against axial load, so the support bearing governs how well the axis keeps position.

Ball screw support bearings for linear axis builds and retrofits

Auxiliary Drive

Keeps the supporting motion of the machine turning, with bearings chosen for the specific radial or axial duty.

Deep groove ball bearings, thrust bearings

Size or full specification

Size alone does not define a precision bearing. A complete line does.

A full enquiry line lets your engineer compare the offer against the machine requirement, including matched bearing sets supplied to the required preload and arrangement.

Alternative rule

Your model is quoted as written. Alternatives stay separate.

An engineering change never passes as a routine substitution, because each alternative is marked on its own line and proceeds only with buyer approval.

Model quoted as specified

  • Keeps the exact NSK specification your equipment or repair record calls for.
  • Stays tied to the shaft position and drawing revision you supplied.
  • Lets engineering and purchasing check the same line.

Alternative marked separately

  • Appears on its own line, apart from the requested model.
  • Goes through your own review as an engineering change.
  • Moves forward only after the buyer approves it.

How to order

Six steps from NSK model to checked delivery

An order moves from a complete enquiry to a written quotation, confirmed shipment and inspection on receipt.

Technician checking a precision bearing on a clean workbench
  1. 1

    Submit the enquiry

    Send by WhatsApp or email: NSK precision model, spindle or feed-axis function, preload, precision and drawing revision, quantities, destination country and postcode, and required date. If a model is incomplete, attach a clear photo of the markings and note the open points.

  2. 2

    Close identification gaps

    Confirm the exact specification, the complete assembly and whether a separately marked alternative may be considered.

  3. 3

    Receive the written quotation

    Review the quoted lines and confirm the product documents available for your order.

  4. 4

    Place the order

    Confirm specification, quantity, delivery details, payment arrangement and commercial terms.

  5. 5

    Confirm shipment

    Agree the transport method, dispatch arrangement and shipping documents for the order.

  6. 6

    Inspect on receipt

    Check labels, quantity and visual condition. Any difference is resolved with the order number and photos.

FAQ

NSK spindle and feed-axis enquiry questions

How do spindle and feed-axis enquiries differ?

They describe different bearing functions, so they should be listed separately. A spindle line typically names the super-precision bearing, arrangement, preload and precision class. A feed-axis line names the ball screw support bearing and the axis it serves.

What should be provided before an alternative is considered?

Provide the original NSK model, shaft function, preload, precision class and drawing revision. If the model is incomplete, add a clear photo of the markings. Any alternative is then marked separately and needs buyer approval.

What does the written quotation list?

It lists product model, quantity, price and currency, stock status and estimated lead time. It also states the quotation validity and the applicable shipping or tax terms.

Can I enquire about a matched bearing set?

Yes. Matched bearing sets are supplied to the required preload and arrangement. State both on the line, together with the NSK model and the machine function.
