Three ways to buy

Buy by single model, matched set or equipment part list.

Each route keeps the exact NSK specification attached to the job. Choose the one that fits how your project is documented.

Single Model

For machine repair and replacement, when the equipment or repair specification already names the bearing.

  • Keeps the exact NSK specification
  • Suits engineers with an approved specification
  • Purchased by model, not only by dimensions

Matched Set

For spindle builds and machine tool rebuilds, when the arrangement and preload are part of the requirement.

  • Specify the matched arrangement
  • State the required preload and precision class
  • Suits precision-machine service leads

Equipment Part List

For whole-machine projects, when auxiliary bearings should be priced with the main precision parts.

  • Reduces separate buying for one machine
  • Separates each line by shaft function
  • Helps procurement track drawing revisions

NSK bearing models you can quote today

Every listing leads to a quote against the NSK model, so the part you price is the part your specification calls for.

Matched bearing sets

Specify the set, not just the size.

NSK matched bearing sets are supplied to the preload and arrangement you require. Put both in your enquiry so the price reflects the set your machine needs.

  1. 1

    Name the complete NSK model

    Use the designation from the machine, repair specification or bearing marking.

  2. 2

    State the arrangement

    Say how the set is mounted: back-to-back, face-to-face or tandem. This decides how it carries load.

  3. 3

    State the required preload and precision

    Preload is the internal load set into the bearings to control stiffness. Give it with the precision class and drawing version.

Quote by shaft position

A spindle is not a feed axis. Your enquiry can show it.

Spindle, feed-axis and auxiliary-drive bearings do different jobs and call for different specification items. Identify each line by function to get a price you can compare.

Comparison of NSK bearing positions, functions, families and specification items to state in an enquiry
Position Function NSK families State in your enquiry
Spindle Main rotating shaft that holds the tool or workpiece. Super-precision angular contact ball bearings, super-precision cylindrical roller bearings, matched sets Complete NSK model, arrangement, preload, precision class, drawing version
Feed axis Supports the ball screw that drives linear axis motion. Ball screw support bearings Complete NSK model, axis function, preload, precision class, drawing version
Auxiliary drive Supporting transmission and defined axial support positions on the machine. Deep groove ball bearings, thrust bearings Complete NSK model, position on the machine, quantity per assembly

Special-environment bearings are quoted by complete NSK model.

Every alternative is marked separately. Every technical change needs your approval.

An engineering change is never handled as a routine substitute. Your specified NSK model stays on the quote, and any alternative sits on its own line for your review.

Written quotation

A quote your engineer can check line by line.

Each written quotation states seven items, so engineering and procurement review the same facts.

  • Product model
  • Quantity
  • Price and currency
  • Stock status
  • Estimated lead time
  • Quotation validity
  • Applicable shipping or tax terms

Buyer questions

NSK bearing purchasing FAQ

How do spindle and feed-axis enquiries differ?

They differ by bearing family and by the function you state. Spindle enquiries usually cover super-precision angular contact or cylindrical roller bearings, with arrangement and preload. Feed-axis enquiries cover ball screw support bearings for the named axis.

What should be provided before an alternative is considered?

Provide the complete NSK model, shaft function, preload, precision class and drawing version. These define what the alternative must be reviewed against. It is then marked separately, and any technical change needs your approval.

What if I do not have the complete NSK model?

Send a clear photo of the bearing markings and note what still needs confirming. The exact specification and complete assembly are settled before you accept a quote.
