§ Start from the repair, not the catalogue

Pick the job on your bench. We confirm the bearings that job needs.

Each scenario below shows what we check before quoting, what to send us, and what a buyer in that situation told us afterwards. Bearings are confirmed by position and complete NSK reference — never by size alone.

Large industrial shaft supported by spherical roller bearings in split plummer block housings

Scenario 05 · Industrial rotating assemblies

List the bearing, the adapter sleeve and the housing together — or the assembly arrives incomplete.

On larger rotating assemblies, a spherical roller bearing is only one part of the position. We confirm bearing, sleeve and housing references as one line so the assembly is complete on arrival.

Per position, send	Why we ask
Full bearing reference	Clearance and execution sit in the suffix
Adapter sleeve model	Tapered-bore bearings mount on a matching sleeve
Housing model	Confirms the assembly is complete, not just the bearing
Drive end / non-drive end	Prevents mixed positions and wrong quantities

Scenario 06 · Distributors buying specified parts

Every line, every quantity, every repeat reference — checked against your last order.

Distributor buyers need repeat orders that match exactly. We check each line's quantity and confirm repeat references are identical to what you bought before, with commercial terms in writing.

§ Machine down today?

Send a clear photo of the old bearing markings and we help confirm the NSK reference.

When a spindle fails and the part number is incomplete, clear photos of the markings on the old bearing let us help identify the correct precision reference before you order.

§ Questions buyers ask

Before you send your bearing list

Are the NSK bearings genuine?+

Yes. NSK Bearings: Source Factory Direct Sales supplies genuine NSK bearings in original NSK packaging with documentation. The written quote confirms which product documents are available for your order.

My maintenance list only has a short stock code. Can you still quote?+

We quote against the complete reference, so we will ask for the missing details first. Send the machine model, bearing position and photos of the old bearing markings, and we confirm seals, clearance and execution before quoting.

Can I replace just one bearing in a spindle set?+

Often it will not restore runout or positioning accuracy. Precision spindles and feed axes rely on matched sets and preload, so we confirm the arrangement for the whole position before quoting.

Will you substitute a different reference?+

Only if you approve it. Any substitute is listed separately on the quote, and technical changes require the buyer's approval.
