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.

Angular contact ball bearing in polished steel on a clean studio background — for machine tool spindles, pumps and compressors

Angular Contact Ball Bearings — 72 / 73 Series & Matched Pairs

NKEN supplies angular contact ball bearings in the 72 and 73 series — single-row, double-row, and matched pairs in DB, DF and DT arrangements — for machine-tool spindles, pumps, compressors and high-speed motors, where combined radial and axial loads and precise shaft guidance matter. Standard 15°, 25° and 40° contact angles are available, with precision grades up to P4 for spindle applications.

Dimensions follow the standard 72/73 series in the table below, so NKEN bearings interchange directly with the bearing you are replacing. Hybrid ceramic executions (Si3N4 balls) for very high speeds are produced on the ceramic line — ask for the hybrid option in your inquiry.
