For machine tool spindles, measuring systems and positioning equipment, the NTN 5S-2LA-HSE9U series delivers the rigidity and rotational accuracy that precision work demands. These single-row angular contact ball bearings handle combined radial and axial loads in one direction, and their design allows fine control of axial clearance for a secure fit in demanding setups.

Reading the part number helps you confirm you are specifying the right execution. The prefix 5S denotes ceramic balls in a hybrid arrangement. The 2LA block covers the cage and lubrication type. HSE identifies the high-speed, precision execution, and 9U marks the single-row angular contact configuration. The digits between HSE and U indicate size: 5S-2LA-HSE910U and 5S-2LA-HSE917U are two examples from the same series, sharing construction details while differing in size.

In US shops and production plants, these bearings are found in milling and grinding machine spindles, machining centers, metrology equipment and industrial robots. They also suit precision transmission points where axial stiffness and high-speed capability are essential. When repeatability and reliable service life matter, this series is a common choice.

Selection depends on the direction of the axial load, the mounting arrangement (single, paired or tandem) and the internal clearance your application requires. Lubrication and sealing also play a role: the 5S-2LA-HSE9U series typically uses a synthetic cage and lubrication specified for high speed. Correct alignment of shaft and housing, along with a proper fit, supports performance and helps avoid premature failure.

If you are replacing a bearing from another manufacturer, we can help you identify a suitable equivalent. Interchangeability is generally based on principal dimensions and execution type, but tolerances and clearance should always be verified. Our team can assist so the replacement meets your application requirements.
