Selection notes

What matters for each equipment type.

Different machines fail in different ways, so the details that decide the right NACHI bearing change too. These are the points we check first for each equipment group.

CNC machine tool spindle head with angular contact ball bearings

01 · Machine tools

Spindle accuracy starts with the precision spindle bearing

Machine tool spindles run on NACHI precision spindle bearings and angular contact ball bearings. Contact angle, precision class, preload and matched arrangement must all match the original set.

  • Precision class and contact angle suffixes confirmed
  • Matched pair arrangement such as DB / DF checked
  • Hard-to-find spindle sizes sourced through our global network

02 · Pumps & gear reducers

Repair replacements depend on an exact cross-reference

Pumps and gear reducers often reach the repair shop with worn markings or discontinued bearings. We cross-reference the old part to the right NACHI deep groove, cylindrical, spherical or tapered roller bearing.

  • Substitutes for discontinued or unreadable models
  • Clearance such as C3 and seal or shield suffix matched
  • Cage material confirmed before quoting

03 · Construction machinery, automotive & general industry

Heavy loads call for the right roller bearing and housing

Construction machinery, automotive and general industrial equipment rely on tapered, spherical and cylindrical roller bearings, plus thrust bearings, plummer block housings and adapter sleeves.

  • Tapered or cylindrical bore variants such as 22220EXK identified
  • Housings and adapter sleeves supplied with the bearing
  • Mixed model lists quoted together for restocking

FAQ

NACHI application questions

Quick answers for maintenance teams and buyers sourcing NACHI bearings from nachioem in Hong Kong.

Can you cross-reference an old or unreadable bearing to a NACHI model?+
Yes. Send the old part number, a photo or the dimensions, and we propose the matching NACHI model or a substitute. We also check clearance, cage and seal suffixes so the replacement fits your equipment.
Do you supply NACHI precision spindle bearings for machine tools?+
Yes. Precision spindle bearings and angular contact ball bearings are part of our range, including hard-to-find sizes sourced through our global supply network. Send the full model number with all suffixes for an accurate quote.
Which shipping methods do you offer?+
We ship by DHL, FedEx, UPS, air freight and sea freight to buyers worldwide. In-stock models are dispatched as soon as the order is confirmed, after inspection, labelling and packing.
Can I order several different models in one quote?+
Yes. Distributors, repair shops and end users can send a mixed list of NACHI models and quantities, and we quote them together. This suits repair work and small-batch restocking.
