Product Description

What this part is

Timken 39575-3 inch-series tapered roller bearing cone: the inner ring with its tapered roller complement and stamped steel cage. Cone only. The matching cup is the Timken 39520. Bore: 2.0000 in. Series: 39500 inch tapered series. Number Of Rows: 1. Rolling Elements: Tapered rollers. Closure Type: Open. Cage Type: Stamped steel. Bearing Material: Bearing steel. Design Units: Inch. Paired with its cup it carries heavy radial load together with thrust in one direction.

Decoding the designation

Part Number: 39575-3. 39575 is the cone number; the matched assembly is written 39575/39520. Precision Class: Timken Class 3, written -3 or *3 — a tighter tolerance than standard on bore, width and running accuracy.

What these specs mean in practice

Class 3 precision gives lower runout and a more predictable mounted fit, which shows up as less running vibration, more even load sharing across the rollers and more repeatable preload setting. Assembly Outside Diameter: 4.4375 in with cup 39520. Assembly Overall Width T: 1.1875 in with cup 39520. Cup Width C: 0.9375 in for the 39520. The cone stands proud of the cup, so the axial setting is made across the mounted pair. Dynamic Load Rating C1: 167,000 N, ISO method over 1 million revolutions, for the complete 39575/39520 assembly. Dynamic Load Rating C90: 43,300 N, Timken method over 90 million revolutions, for the same assembly. Static Load Rating C0: 224,000 N for the complete assembly. C1 and C90 are two rating conventions over two different lives. Harmonization Code: 8482.20.00.

Quantity and configuration

Unit Quantity: 1 Pc. Single-row separable tapered design. The cone runs against the 39520 cup and the pair is normally mounted opposed to a second tapered bearing, which sets endplay or preload on assembly.

Interchange guidance

Searchable forms of the designation: 39575, 39575-3, 39575 3, 39575*3, 395753. Cross-references: 39520 (mating cup), 39575/39520 (complete matched assembly designation), 39575 (cone base number, standard precision). Fafnir bearing numbers sit under Timken.
