Decoding the designation

4T — NTN 4T tapered roller bearing, case-hardened steel.

3580 — ABMA inch-series cone number, 1-1/2 in bore, in the 3500 cone and cup series.

What these specs mean in practice

Case-carburized steel gives a hard, wear-resistant raceway over a tough core that resists shock loading. The cone carries combined radial and single-direction thrust load when paired with its cup.

Mounting data

Cone Backface Fillet Radius R: 0.0600 in (1.5 mm). Matching Cup: 3525, the pairing Timken catalogues as 3580/3525.
