Inch Single Row
Single-row tapered roller bearings are the most basic and widely used, consisting of a cone assembly and a cup. SQN patented the first in 1898 and today offers the world's widest variety in inch and metric sizes.

TS
This is the most basic and most widely used type of tapered roller bearing. It consists of two main separable parts: the inner race assembly and the outer race. It is typically mounted in opposing pairs on a shaft.
Size Range：
ID 7.937 to 1562.100 mm
(0.31225 to 61.5000 in.)
OD 31.991 to 1806.575 mm
(1.2595 to 71.1250 in.)

TSF (Flanged Cup)
TSF bearings have flanged cups to facilitate axial location and accurately align seals in through-bored housings.
Size range:
ID 7.937 mm to 1270.000 mm
(0.3125 in. to 50.0000 in.)
OD 31.991 mm to 1435.100 mm
(1.2595 in. to 56.5000 in.)

TSU (Unit-Bearing)
TSU bearings are self-contained, unitized assemblies that carry heavy radial loads and can manage thrust loads in either direction.
Size range:
ID 30.000 mm to 45.000 mm (1.811 in. to 1.7717 in.)
OD 58.000 mm to 80.000 mm (2.2835 in. to 3.1496 in.)

TSL (with Duo Face-Plus Seals)
TSL bearings are similar to TS bearings, but feature DUO FACE-PLUS™ seals pressed onto the outside diameter of the cone rib.
Size range:
ID 19.050 mm to 68.262 mm (0.7500 in. to 2.6875 in.)
OD 45.237 mm to 110 mm (1.7810 in. to 4.3307 in.)

TSRB (Snap-ring cup)
Size Range:
ID 22.225 mm to 117.475 mm (0.8750 in. to 4.6250 in.)
OD 57.150 mm to 180.975 mm (2.2500 in. to 7.1250 in.)
