Decoding the designation

3583 — the cone number, an inch-series tapered roller cone on a 1.5000 in bore with a 1.2160 in inner ring width.

3520 — the cup number Timken pairs with the 3583 cone, giving a 3.3125 in outside diameter and a 0.9375 in outer ring width.

Precision Class: Not specified. Timken marks Class 3 with an explicit –3, *3 or #3 and Class 2 with an explicit –2; neither marking is carried here.

What these specs mean in practice

Dynamic Load Rating (C1): 113,000 N (25,500 lbf). Dynamic Radial Load Rating (C90): 29,400 N (6,610 lbf). Dynamic Axial Rating (Ca90): 15,400 N (3,460 lbf). Static Load Rating: 134,000 N (30,100 lbf).

K Factor: 1.91. The K factor is the ratio of radial to thrust capability; a value near 1.9 puts this bearing in the shallow-angle group, carrying a high radial share with a moderate thrust share.

e Factor: 0.31. Y Factor: 1.96. These load-zone factors convert a combined radial and thrust load into an equivalent radial load for life calculation.

Item weight: 2.1 kg (4.6 lb) for the two pieces. Cone Weight: 1.4 kg (3.1 lb). Cup Weight: 0.7 kg (1.5 lb).

Mounting data

Effective Center Location: –0.4 in (–10.2 mm), measured inside the cone backface.

Max Shaft Fillet Radius: 0.140 in (3.600 mm). Max Housing Fillet Radius: 0.130 in (3.30 mm).

Shaft Backing Shoulder Diameter, frontface (da): 1.79 in (45.5 mm). Shaft Backing Shoulder Diameter, backface (db): 2.05 in (52 mm).

Housing Backing Shoulder Diameter, frontface (Da): 3.15 in (80.00 mm). Housing Backing Shoulder Diameter, backface (Db): 2.91 in (73.91 mm).

Quantity and configuration

Cone and cup, 2 Pcs. Unit Quantity: 2 Pcs. The 3583 cone carries the inner race, the roller set and the cage; the 3520 cup is the outer race. Timken lists the 3520 as a mating cup for the 3583 cone, so the two form one factory-paired single-row tapered roller bearing.

Interchange guidance

3583 and 3520 are standard ABMA inch tapered roller numbers, so other makers list the same cone and cup under their own prefixes: NTN 4T-3583/3520, SKF 3583/3520, FAG K3583-3520, NSK 3583/3520, Koyo 3583/3520, Fersa 3583/3520, BCA/Bower 3583/3520 and PEER 3583/3520.

MPN Variants: 3583/3520, 3583-3520, 3583 3520.
