Frequently asked questions about NU204
What does the open design mean on a NU204 bearing?
The NU204 (20mm x 47mm x 14mm) is supplied open — without seals or shields — so lubrication and relubrication come from the surrounding housing or an external system. Compare seal types before deciding on the replacement.
Which part numbers are equivalent to NU204?
Equivalent designations include NU204ECP, NU204E.TVP2, NU204EM . These are brand-specific numbers for the same ISO boundary dimensions as the NU204 (20mm x 47mm x 14mm). The basic number matching does not confirm the complete specification — compare seal type, clearance, precision, cage, and lubrication suffix before ordering.
Does the NU204 come with C3 clearance?
This directory lists the NU204 with CN (Standard). C3 (increased internal clearance) versions are common for higher operating temperatures, higher speeds, or press-fit arrangements — specify the required clearance on your RFQ so the quotation matches the application. Read the clearance guide.
The NU204 is listed as a 20×47×14mm cylindrical roller bearing in open configuration. Part of the NU200 series, the directory records chrome steel gcr15 and P0 (ABEC-1) precision grade for RFQ verification.
The NU204 bearing cross-references to SKF NU204ECP, FAG NU204E.TVP2 and NSK NU204EM. This means you can replace an SKF equivalent, FAG alternative, NSK cross reference, or NTN interchange part with the same ISO boundary dimensions. Compare the full specification table and designation suffixes before ordering, especially the seal type (2RS vs ZZ) and internal clearance (C3 vs CN).
About the NU200 Series
The NU200 series is a single row cylindrical roller bearing with two integral flanges on the outer ring and a plain inner ring. The separable design allows the inner ring to be removed, simplifying installation. Optimized for high radial loads at moderate to high speeds.
