About Inch Tapered Roller Bearings

The rolling elements of a tapered roller bearing are tapered rollers, forming a line contact with the raceways of the inner ring (cone) and outer ring (cup). They are separable bearings, available in both metric and inch dimensions.

They can be made to special dimensional requirements within basic design limitations.

  • Capable of carrying high radial loads as well as axial loads in one direction
  • Suitable for low and medium speed applications
  • Normally mounted in pairs for axial location in both directions

Available Variants

  • Single row types — 302, 303, 303D, 320, 322, 323, 330, 331 and 332 series
  • Double row type — DRT (details available on request)
  • Four row type — FRT (details available on request)
  • Precision grade P0 and higher precision grade P6

Suffix Codes

Add these suffixes to the bearing number to specify clearance, cage and bore options.

SuffixMeaning
AModified internal design.
AR / RAFlange on the cup.
DUsed with 303 series to denote equivalence to the 313 series of other brands.
MMachined brass cage.
PPolyamide cage.
P6Dimensional and running accuracy conforming to ISO class 6.

Typical Applications

  • Wheel hubs and axle assemblies
  • Gearboxes and differentials
  • Rolling mills and heavy machinery
  • Machine tool spindles and conveyor drives

Frequently Asked Questions

What sizes are available in the INCH-2 series?

INCH-2 series bearings are available from 23.812mm – 28.575mm bore, as listed in the dimension table on this page. Each size has its own bearing number for ordering.

What load ratings apply to INCH-2 bearings?

Dynamic and static load ratings vary by size — see the table for the exact rating per bearing number. Larger sizes carry proportionally higher load ratings.

What is the INCH-2 series typically used for?

Common applications include wheel hubs and axle assemblies and gearboxes and differentials, and similar general industrial equipment.

Are these tapered roller bearings in inch sizes?

Yes. These are inch-series bearings listed by cone and cup number (for example cone/cup pair 4050/4138); all dimensions are shown in millimetres.

Can I order INCH-2 series bearings with special options?

Yes. Many options are available — see the variants and suffix codes on this page — subject to design and manufacturing constraints. Share your requirement in a quote request.
