| Inch series single row tapered roller bearings |
 |
 |
Inch single row tapered roller bearings are different from the metric bearings in structure, mounting dimension and rotate speed precision. Inch single row Tapered roller bearings are generally of separable design and have tapered cone and cup raceway between which tapered roller are arranged, their design makes Inch single-row tapered roller bearings particularly suitable for carrying combined (radial and axial ) load |
 |
Tapered roller bearings can be disassembled into parts .. the inner ring, rollers, and cage (collectively known as the "cone") .. and the outer ring (known as the "cup"). These are the bearing’s "subunits". Subunit dimensions are standardized under ISO or ABMA standards, and unified subunits are interchangeable within each dimensional standard. However, high precision grade bearings are generally not interchangeable, and these subunits must be used by assembling only subunits with identical manufacturing numbers. |
| Aside from any cautionary notes that may appear, the single row tapered roller bearings listed in the dimension tables have subunits standardized for both metric and inch systems (including J series) (Refer to Diagram 2) |
| These bearings are constructed to have a high capacity for radial loads, axial loads, and combined loads. The larger the contact angle, the greater the axial load capacity becomes. When a pure radial load is placed on the bearings, an induced load in the axial direction is also generated, and so these bearings are generally used in pairs arranged face to face. |
 |
|
When used in pairs, proper internal clearances and preload can be set by adjusting the distance between the two bearings' inner and outer rings. |
