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.

Cylindrical roller bearing NU series with brass cage, for electric motors and gearboxes

Cylindrical Roller Bearings — NU / NJ / NUP / NN Series

NKEN manufactures cylindrical roller bearings in the NU, NJ, NUP, N, NF and NN series, single- and double-row, at the Shandong factory — one of the group's two main production bases. Line contact and a separable design make these bearings the standard choice for electric motors, gearboxes, pumps and machine tools: high radial capacity, fast mounting, and free axial shaft movement on NU/N types.

All 294 NU models from our model library are listed in the full table below with dimensions and load ratings; NJ, NUP, N and NF share the same boundary dimensions for the same number. Brass, steel and polyamide cage options, plus C3 clearance and insulated executions, are available — see the electrically insulated bearings page for coated motor bearings.

Cylindrical Roller Bearings — questions buyers ask

Is the NU310 bearing available with a brass cage?

Yes — NU310 (50 × 110 × 27 mm) is supplied with pressed-steel or machined-brass (M) cage. Add the cage suffix you need, or tell us the application and we will specify it.

Can you supply insulated NU bearings for VFD motors?

Yes, cylindrical roller bearings are available with ceramic insulation coating in the industry-standard VL / J20 insulation classes — see the Electrically Insulated Bearings page or ask in your inquiry.

What is the difference between NU and NJ?

NU has two ribs on the outer ring and none on the inner ring, so the shaft floats axially; NJ locates the shaft in one direction. Both share the same boundary dimensions for the same model number.
