Frequently asked questions about 7303
What does the open design mean on a 7303 bearing?
The 7303 (17mm 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 7303?
Equivalent designations include 7303BEP, 7303B.TVP, 7303A . These are brand-specific numbers for the same ISO boundary dimensions as the 7303 (17mm 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 7303 come with C3 clearance?
This directory lists the 7303 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 7303 is listed as a 17×47×14mm angular contact bearing in open configuration. Part of the 7300 series, the directory records chrome steel gcr15 and P0 (ABEC-1) precision grade for RFQ verification.
The 7303 bearing cross-references to SKF 7303BEP, FAG 7303B.TVP and NSK 7303A. 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 7300 Series
The 7300 series angular contact ball bearings have a larger cross-section than the 7200 series, providing higher load capacity. Ideal for heavy-duty machine tool applications with combined loads.
