NATA59 Series<\/strong><\/strong><\/strong><\/h4><\/div><\/div><\/div>\n<\/div>\n\n\n\n
\n

Structure:<\/strong> NATA bearings consist of a needle roller bearing and an angular contact ball bearing combined in a single unit.
Load Capacity:<\/strong> They can support high radial loads (from the needle rollers) and axial loads in both directions (from the angular contact ball bearing).
Separable Design:<\/strong> Many NATA bearings are separable, meaning the inner ring can be removed from the outer ring and rolling elements, which can be helpful for installation and maintenance.
Applications:<\/strong> Used in gearboxes, machine tools, automotive transmissions, and other machinery where both radial and bidirectional axial loads need to be supported in a compact space.<\/p><\/div><\/div><\/div>\n<\/div>\n<\/div>\n\n\n\n

NKIB Series<\/strong><\/strong><\/strong><\/h4><\/div><\/div><\/div>\n<\/div>\n\n\n\n
\n

Structure:<\/strong> NKIB bearings combine a needle roller bearing (for radial load) with an angular contact ball bearing (for axial load in both directions) in a single unit.
Axial Load:<\/strong> Unlike NKIA bearings (which only support axial load in one direction), NKIB bearings can support axial loads in both directions.
Separable Inner Ring:<\/strong> The inner ring of NKIB bearings is usually split, which allows for easier mounting and dismounting, especially when both radial and axial loads are present.
Applications:<\/strong> Commonly used in gearboxes, automotive transmissions, machine tools, and other machinery where both radial and bidirectional axial loads need to be supported in a compact space.
Designations:<\/strong> Examples include NKIB5906, NKIB5907, etc., where the numbers indicate the size.<\/p><\/div><\/div><\/div>\n<\/div>\n<\/div>\n\n\n\n

\n

Structure:<\/strong> NATB bearings combine a needle roller bearing (for high radial load capacity) with an angular contact ball bearing (for axial load capacity in both directions) in a single, compact unit.
Axial Load:<\/strong> NATB bearings can support axial loads in both directions, thanks to the angular contact ball bearing component.
Separable Inner Ring:<\/strong> The inner ring is usually split, which allows for easier mounting and dismounting, especially when both radial and axial loads are present.

Structure:<\/strong> NKX bearings consist of a needle roller bearing (for radial load) combined with a thrust ball bearing (for axial load in one direction) in a single unit.
Axial Load:<\/strong> NKX bearings can support axial loads in one direction only.
Non-separable:<\/strong> The bearing is generally non-separable, meaning the components are assembled as a single unit.
Applications:<\/strong> Commonly used in machine tools, automotive transmissions, pumps, and other machinery where both radial and unidirectional axial loads need to be supported in a compact space.

ZARN Series<\/strong><\/strong><\/strong><\/h4><\/div><\/div><\/div>\n<\/div>\n\n\n\n
\n

Structure:<\/strong> ZARN bearings consist of a double direction axial cylindrical roller and cage assembly (for high axial load in both directions) and a radial needle roller bearing (for moderate radial load). The bearing is non-separable and compact.
Axial Load:<\/strong> ZARN bearings can support very high axial loads in both directions, making them ideal for screw support applications.
Radial Load:<\/strong> They also support moderate radial loads, thanks to the integrated needle roller bearing.
Preload:<\/strong> ZARN bearings can be preloaded to increase rigidity, which is important for precision applications like machine tool spindles and ball screw supports.

Applications:<\/strong>
Commonly used in:
Ball screw support in CNC machines
Machine tool spindles
Precision machinery
Robotics

Designations:<\/strong>
Examples include ZARN1545, ZARN2052, ZARN2572, etc., where the numbers indicate the size (bore diameter and width).

Variants<\/strong>
ZARN:<\/strong> Standard type, with a full complement of rolling elements.

The Ultimate Space-Saving Solution for Complex Loads<\/strong><\/h2>\n\n\n\n

When radial space is severely restricted but the shaft must support both heavy radial forces and significant axial thrust, standard bearing arrangements are often too bulky.
ZMS Combined Needle Roller Bearings<\/strong> solve this by integrating a radial needle roller bearing with a thrust bearing component (either a ball or cylindrical roller) into one highly compact, ready-to-mount unit.<\/p>\n\n\n\n

    Ideal Applications for Combined Bearings<\/strong><\/h2>\n\n\n\n

    Because of their unmatched cross-sectional compactness and multi-directional load capabilities, ZMS combined bearings are the preferred choice for multi-spindle drilling heads, machine tool indexing mechanisms, textile machinery, and automated packaging equipment.<\/p>\n\n\n\n
