30203J Single-Row Tapered Roller Bearing
The 30203J single-row tapered roller bearing is a compact metric bearing assembly for B2B sourcing and manufacturer-reference comparison. The 30203 product cluster uses a 17 mm bore, 40 mm outside diameter, and 13.25 mm overall width across the verified NSK 30203J, JTEKT/Koyo 30203JR, SKF 30203, and FAG 30203A reference configurations. DUHUI can confirm the final designation, suffix, supply scope, marking, and packaging during quotation.

Product Features
- The single-row tapered roller design carries combined radial and axial loads, with axial load supported in one direction.
- The 17 x 40 x 13.25 mm metric envelope provides a clear dimensional checkpoint across the verified 30203 family references.
- NSK 30203J is specified as a complete standard-precision assembly with one cone, one cup, and a pressed steel cage.
- Separate NSK, JTEKT/Koyo, SKF, and FAG designations give procurement teams practical reference points without merging manufacturer-specific ratings or suffix meanings.
30203J Ordering Verification
- Match the inquiry to Part Number 30203J and the required manufacturer-equivalent designation.
- Confirm the 17 mm bore, 40 mm outside diameter, 13.25 mm overall width, and required bearing quantity.
- Specify the required manufacturer-equivalent designation, complete assembly scope, and any final suffix or marking requirement.
