Timken3583/3530Tapered Roller Bearing Cone and Cup Set – 1.5000 in Bore, 3.3125 in Outside Diameter, 1.1875 in Width, 113,000 N Dynamic Load Rating

Product Description

What this part is:

Timken 3583/3530 inch tapered roller bearing set, a TS assembly pairing the 3583 single cone with the 3530 single cup. Bore Diameter: 1.5000 in (38.1 mm). Outside Diameter: 3.3125 in (84.138 mm). Overall Width: 1.1875 in (30.163 mm). Cone Width: 1.2160 in (30.886 mm). Cup Width: 0.9375 in (23.813 mm). Series: 3500. Base Number: 3583. Rolling Elements: Tapered Roller. Number Of Rows: 1. Bore Type: Straight. Bearing Material: Case-Carburized Steel. Item Weight: 0.8 kg (1.8 lb). Design Units: Imperial.

Decoding the designation:

3583 — the cone number, fixing the 1.5000 in bore and the raceway angle.

3530 — the cup number, fixing the 3.3125 in outside diameter and the matching raceway.

What these specs mean in practice:

Dynamic Load Rating: 113,000 N (25,500 lbf) at 1 million revolutions. Static Load Rating: 134,000 N (30,100 lbf). Dynamic Radial Rating C90: 29,400 N (6,610 lbf). Dynamic Axial Rating Ca90: 15,400 N (3,460 lbf). K Factor: 1.91. e Factor: 0.31. Y Factor: 1.96. G1 Factor: 39.5. G2 Factor: 10.5. Geometry Factor (Cg): 0.0808.

A K factor of 1.91 is a shallow raceway angle, which puts most of the capacity into radial load: 113,000 N radial against 15,400 N of thrust at the 90-million-revolution rating. That suits shafts carrying heavy radial load with modest axial location duty.

Mounting data:

Effective Center Location: -0.4 in (-10.2 mm), the load centre lying inside the cone backface. Max Shaft Fillet Radius: 0.140 in (3.600 mm). Max Housing Fillet Radius: 0.03 in (0.76 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): 2.99 in (75.95 mm). Cage Location relative to backface (Aa): 0.07 in (1.8 mm). Cage Location relative to frontface (Ab): 0.05 in (1.3 mm). Precision Class: Not specified.

Quantity and configuration:

Unit Quantity: 2 Pcs. One 3583 cone and one 3530 cup, supplied together as the set.

Interchange guidance:

The 3583/3530 designation is the shared inch tapered roller bearing number, so it is carried by SKF, NSK, Koyo, Fersa, Bower/BCA and PEER as 3583/3530, by NTN with its 4T- prefix as 4T-3583/3530, and by FAG with its K- cone prefix as K-3583/K-3530. Searchable variants: 3583/3530, 3583 3530, 3583 / 3530.
