Tapered Roller Bearing Description:

Taperedroller ring included cup and cone there two parts.Cup is outer ring, Cone comprise rollers,cage,inner ring.And the inner ring with the rollers and cage can be fitted separately from the outer ring.The tapered roller bearings are generally used to support comnined load mainly consisting of radial load. The carrying capacity of axial load depends on the contact angle of raceway of outer rings. The bigger the contact angle is, the strongerr the capacity will be.

The kinds of tapered roller bearing and models:                      

Single row tapered roller bearing

TS (pressed steel cage) 
ID 0.3125 to 34.0000 in. (7.937 to 863.600 mm)
OD 1.2595 to 41.7323 in. (31.991 to 1060.000 mm ) 
Design attributes:
          * Single cone and cup
          * One-piece pressed steel cage retains rollers on the cone and spaces them evenly 
Potential applications: vehicle front wheels, differential and pinion configurations; conveyor rolls; machine tool spindles; trailer wheels 
 
TS (pin-type cage) 
ID 6.0000 to 67.0000 in. (152.400 to 1701.800 mm)
OD 12.1250 to 80.0000 in. (307.975 to 2032.000 mm) 
Design attributes:
          * Additional rollers accommodate larger loads
          * Cage features two rings at each end of the rollers
          * Cage pins are threaded in the center of each roller and welded at the ends 
Potential applications: larger-load automotive and industrial equipment configurations.

TSF (flanged cup)

ID 0.3125 to 50.0000 in. (7.937 to 1270.000 mm)
OD 1.2595 to 56.5000 in. (31.991 to 1435.100 mm)

Double row tapered roller bearing

TDO (two-row double-outer race) 
ID 1.0000 to 47.2500 in. (25.400 to 1200.150 mm)
OD 1.2000 to 96.8504 in. (30.480 to 2460.000 mm) 
Design attributes:
          * Double cup and two single cones, with or without a spacer
          * When spacers are used, bearing is furnished as a preset, matched assembly
          * Cup features groove and lubrication holes in the OD
          * Spacers available with or without lubricant grooves and holes 
Potential applications: Heavy-duty gear drives and a variety of industrial configurations.

TDI (two-row double-inner race)

ID 1.0000 to 47.2500 in. (25.400 to 1200.150 mm)
OD 1.2000 to 96.8504 in. (30.480 to 2460.000 mm)

TDIT (two-row double-inner race) 
ID 1.0000 to 47.2500 in. (25.400 to 1200.150 mm)
OD 1.2000 to 96.8504 in. (30.480 to 2460.000 mm)

TNA (two-row non-adjustable/TNA with lubrication grooves/TNA with extended ribs)

TNASW/TNASWE

TNASW/TNASWE 
Design attributes:
          * Double cup and two single cones
          * Internal bearing clearance controlled by extending the front faces of the cones so they contact each other 
          * SW variation features chamfers in the bores at the front faces of the two single cones to form a lubrication groove
          Potential applications: sheaves, crane sheaves, oil-field drilling rig sheaves and applications where two-row preset bearings are required.

 * SE variation features a backface rib design to accommodate radial lip seals or stamped closure.
