What is the minimum order quantity (MOQ)?

Stock models can be supplied in small quantities, and non-standard bearings can be custom-made even in small batches. Send us the model number or drawing and we will confirm the MOQ with your quotation.

Can you supply bearings under our own brand?

Yes. NKEN offers full OEM service: your brand laser-marked on the bearing rings, custom colour boxes and labels, so the goods arrive ready for your shelf.

Do you provide free samples?

Yes, free samples are available for most catalogue models so you can test quality and fit before placing a bulk order.

What information do you need to quote?

The bearing model number (or the brand cross-reference number you currently buy), quantity, delivery destination, and any special requirements such as clearance, seals or branding. A drawing is enough for non-standard parts.

Which countries do you export to?

NKEN bearings are exported to more than 73 countries, with sea and air shipping options and export packing as standard.

Large-diameter ball bearing ring with polished steel balls and bright machined races — NKEN oilfield & drilling bearings: rotary-table thrust, hook thrust and mud-pump bearings for drilling rigs

Oilfield & Drilling Bearings — Rotary Table, Hook & Mud Pump

NKEN supplies bearings built for drilling-rig duty: rotary-table thrust bearings, hook thrust bearings and mud-pump cylindrical roller bearings, matched to the original-equipment designations rig maintenance crews already specify. These are shock-loaded, contamination-exposed positions where failure stops the rig — so every oilfield bearing is specified against the original equipment reference before we quote.

The line is completed by a service almost no catalogue supplier offers: renovation of large bearings from 2 in inside diameter up to 100 in outside diameter — raceway regrinding, new rolling elements and cage repair that return an oversize bearing to service at a fraction of new cost and lead time. Send the bearing reference or the rig equipment model to start.

Oilfield & Drilling Bearings — questions buyers ask

Can you supply the thrust bearing for our rotary table model?

Yes — give us the table make and model, or the old bearing's designation/dimensions, and we specify and quote the NKEN equivalent.

What bearings can be renovated?

Large bearings from 2 in ID up to 100 in OD: raceways are reground, rolling elements replaced and cages repaired as needed. Send photos and dimensions for an assessment and quotation.

Can you match the oilfield bearing number we use now?

Yes — our oilfield programme is indexed against original-equipment designations, so quote the number you use and we match the NKEN bearing.
