Frequently asked questions about 7203
What does the open design mean on a 7203 bearing?
The 7203 (17mm x 40mm x 12mm) 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 7203?
Equivalent designations include 7203BEP, 7203B.TVP, 7203A . These are brand-specific numbers for the same ISO boundary dimensions as the 7203 (17mm x 40mm x 12mm). The basic number matching does not confirm the complete specification — compare seal type, clearance, precision, cage, and lubrication suffix before ordering.
Does the 7203 come with C3 clearance?
This directory lists the 7203 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 7203 is listed as a 17×40×12mm angular contact bearing in open configuration. Part of the 7200 series, the directory records chrome steel gcr15 and P0 (ABEC-1) precision grade for RFQ verification.
The 7203 bearing cross-references to SKF 7203BEP, FAG 7203B.TVP and NSK 7203A. 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 7200 Series
The 7200 series is a single row angular contact ball bearing with a 40° contact angle. Designed for combined radial and axial loads at high speeds. Often used in matched pairs (face-to-face, back-to-back, or tandem) in machine tool spindles and high-speed pumps.
Common Applications
- Machine Tool Spindles
- High-Speed Pumps
