About NTN Bearing Asm

An independent brand for compatible replacement bearings, built to ISO boundary dimensions.

What we supply

We manufacture and supply compatible replacement rolling bearings for industrial aftermarket buyers: single row deep groove ball bearings (60/62/63 series) and metric single row tapered roller bearings in the 302, 303, 320, 322 and 323 dimension series, plus double row spherical roller bearings (213xx, 222xx, 223xx and 230/231/232 series). Every designation in our catalogue is produced to ISO boundary dimensions, so it is dimensionally interchangeable with the corresponding industry designations — including NTN-series designations our customers reference every day.

How we control quality

Each production batch goes through 100% dimensional inspection (bore, outside diameter, width), clearance and seal checks before packing. Inspection records are kept per batch and can be shared with your quotation on request, so what you approve is what you receive.

How buying works

Add the models you need to the enquiry list and send it as one request. We reply with a quotation within one business day, covering quantity pricing, clearance and seal options, packaging and lead time. Confirmed orders move to a proforma invoice, then production or stock allocation, then shipment with the paperwork your customs broker needs.
