Product Description

What this part is:

Timken 16131/16282 single-row inch tapered roller bearing, supplied as a matched cone and cup. Cone Part Number: 16131. Cup Part Number: 16282. Rolling Elements: Tapered Roller. Number Of Rows: 1. Bore Type: Straight. Design Units: Imperial. Bore Diameter: 1.3125 in (33.338 mm). Outside Diameter: 2.8346 in (71.999 mm). Overall Width (T): 0.7480 in (18.999 mm). Cone Width: 0.8125 in (20.638 mm). Cup Width: 0.5605 in (14.237 mm). Series: 16000. Bearing Material: Case-Carburized Steel. Harmonization Code: 8482.20.00.

Decoding the designation:

16131 — the cone number, a 16000-series inch tapered roller cone on a 1.3125 in bore.

16282 — the cup number Timken pairs with the 16131 cone, giving a 2.8346 in outside diameter.

90028 — the Timken assembly marking carried on the carton, recorded as an MPN variant.

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): 56,600 N (12,700 lbf). Dynamic Radial Load Rating (C90): 14,700 N (3,300 lbf). Dynamic Axial Rating (Ca90): 10,100 N (2,270 lbf). Static Load Rating (C0): 65,800 N (14,800 lbf).

K Factor: 1.45. A K factor of 1.45 sits in the steeper group, so the bearing takes a larger thrust share for a given radial load than a 1.9-class taper of the same envelope.

e Factor: 0.40. Y Factor: 1.49. These load-zone factors convert a combined radial and thrust load into an equivalent radial load for life calculation.

The assembled width of 0.7480 in is narrower than the cone ring width of 0.8125 in, because the cone and cup overlap on the raceway taper when the bearing is seated.

Item weight: 0.4 kg (0.8 lb).

Mounting data:

Effective Center Location: –0.16 in (–4.1 mm), measured inside the cone backface.

Max Shaft Fillet Radius: 0.140 in (3.600 mm). Max Housing Fillet Radius: 0.06 in (1.52 mm).

Shaft Backing Shoulder Diameter, frontface (da): 1.56 in (39.5 mm). Shaft Backing Shoulder Diameter, backface (db): 1.81 in (46 mm).

Housing Backing Shoulder Diameter, frontface (Da): 2.68 in (67.10 mm). Housing Backing Shoulder Diameter, backface (Db): 2.48 in (62.99 mm).

Quantity and configuration:

Cone and cup, 2 Pcs. Unit Quantity: 2 Pcs. The 16131 cone carries the inner race, the roller set and the cage; the 16282 cup is the outer race. Timken catalogues the pair as one TS single-row assembly.

Interchange guidance:

16131 and 16282 are standard inch tapered roller numbers and the same digits are carried across the trade. Cross-references: SKF 16131/16282, FAG K16131-16282, NSK 16131/16282, NTN 4T-16131/16282, Koyo 16131/16282, Fersa 16131/16282, BCA/Bower 16131/16282, PEER 16131/16282.
