Linear motion ball bearings

Characteristics

Linear motion ball bearings are composed of a sleeved outer ring and a cage-multi-row balls assembly.

These bearings can make a linearly reciprocating motion on a shaft in axial directions.

They are specialized in multi-row balls, less frictional moment, light and mobility, and long life.

The bearing designs bring together within low cost application, simplified maintenance and convenient interchangeability for end users.

Structural features

LB TN (ZX-), normal type bearings with normal class P tolerances and precision class T tolerances.

LB AJTN (ZX-t), bearings with axial cut out in the sleeved outer ring which can be adjusted radial internal clearance.

LB OPTN (ZX-k), bearings with sectorial cut out in the sleeved outer ring which can be mounted on the shaft with a stay, so as to adjust radial with a stay, so as to adjust radial internal clearance.

Semicircle type bearings, i.e. half s standard bearings, which can be mounted radially and used to support the shaft partially.

Designations for linear motion ball bearings

Tolerances

Linear motion ball bearings are manufactured to normal class tolerances P and precision class tolerances J.

Special series bearings are only manufactured to normal class tolerances.

Size deviation at all level refer to the data in the table.
