Introduction:

In the realm of machinery and mechanical systems, precision in axial motion is essential for optimal performance and efficiency. Axial angular contact ball bearings play a critical role in facilitating precise axial movements, particularly in high-speed and high-precision applications. Among the variety of axial angular contact ball bearings available, the 2344 and 2347 series stand out for their precision engineering and reliability. This article delves into the features, advantages, and applications of these bearings, highlighting their significance in driving efficiency and accuracy in axial motion control.

Precision Engineering for Axial Motion:

The 2344 and 2347 series of axial angular contact ball bearings are meticulously engineered to deliver precision in axial motion. Their design incorporates raceways inclined at an angle to the bearing axis, enabling them to accommodate both axial and radial loads simultaneously. This innovative design minimizes friction and ensures smooth axial motion, contributing to optimal performance in a wide range of industrial applications.

It consists of two shaft rings, one seat ring, one spacer and two rows of rolling elements and cage assembly. The clearance and preload of the bearing can be adjusted by grinding the thickness of the spacer. The contact angle of the bearing is 60°. The outer diameter of the bearing and its supporting double row cylindrical roller bearings with the same outer diameter, but the outer ring and the box hole between the gap, therefore, two-way thrust angular joint ball bearings do not bear radial load, and double row cylindrical roller bearings supporting the use of in order to withstand bidirectional axial load;.

With high precision, good rigidity, low temperature rise, high speed, easy loading and unloading and other advantages.


Two-way thrust angular joint ball bearings are divided into 2344 and 2347 two size series, 2344 series bearings are used with double rows of cylindrical roller bearings taper hole small end fit, 2347 series used for large end fit.
