Double direction angular contact thrust ball bearings
Double direction angular contact thrust ball bearings were developed  to axially locate spindles in both directions. These bearings are intended for mounting in combination with cylindrical roller bearings in the NN 30 K or N 10 K series in the same housing bore. This bearing combination simplifies machining of the housing bore.

Double direction angular contact thrust ball bearings are manufactured with the same bore size and nominal outside diameter as corresponding cylindrical roller bearings. However, the tolerance of the housing washer outside diameter, combined with the recommended
housing fit, results in an appropriate radial clearance in the housing bore. This clearance prevents radial loads from acting on the thrust bearing.

Basic design bearings, 2344(00) series
1.a one-piece housing washer
2.two ball and cage assemblies with a large number of balls
3.two shaft washers separated by a spacer sleeve.

When mounted, these bearings become preloaded. The preload, combined with the 60° contact angle and the large number of balls provides a high degree of axial stiffness. Their optimized cage design makes these bearings suitable for relatively high-speed applications. To facilitate efficient lubrication, the bearings have an annular groove and three lubrication holes in the housing washer.
234448m High Precision Angular Contact Ball Bearing Dimensions
The dimensions of  double direction angular contact thrust ball bearings are not standardized but are generally accepted by the market. The bore and outside diameters of bearings in the 2344(00) series correspond to Diameter Series  for radial bearings and are in accordance with ISO standard.

Tolerances
Basic design angular contact thrust ball bearings in the 2344(00) series are made to SP (Special Precision) tolerance class as standard. Bearings made to the UP (Ultra Precision) higher tolerance class can be supplied to order.

234448m High Precision Angular Contact Ball Bearing Preload
Double direction angular contact thrust ball bearings are manufactured as standard with a predetermined preload so that they will have a suitable operational preload after mounting. The preload of basic design bearings in the 2344(00) series is adjusted by setting the width of the spacer sleeve.

Cages
two separate machined brass cages, ball centred, designation suffix M.
The standard cage for bearings in the 2344(00) series is indicated in the product table designations.

Attainable speeds
The "Attainable speeds" quoted in the product tables are guideline values and valid for bearings in the 2344(00) series with standard preload.
Provided they are fitted on a shaft machined to h4 tolerance, lightly loaded (P ` 0,05 C) and that heat dissipation from the bearing position is good.
