NAA15XL0 Four-point Contact Ball Bearing (type X), Nylon Cage
The NAA15XL0 Thin-section four-point contact ball bearings are widely used in fields with stringent space and precision requirements, including: industrial robots (wrist and elbow joints), medical equipment (CT scanner rotating frames, surgical robots), aerospace (satellite antenna drive mechanisms), semiconductor equipment (wafer handling robotic arms), optical instruments (laser trackers, precision rotary tables), and precision machine tools (rotary worktables).
The NAA15XL0 bearing is a Thin-section bearings with an inner diameter of 1.5 inch , an outer diameter of 1.8752 inch, a width of 0.1875 inch. It typically uses Precision Class 1 per ABEC 1F grade precision tolerances and AISI 52100 steel rings, AISI 52100 steel rolling mlement. Its dynamic radial rated load is approximately 1311.2 N, its static radial rated load is approximately 1778 N. Its dynamic axial rated load is approximately 1987 N, its static axial rated load is approximately 4362 N. open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
NAA15XL0 bearings ( 1.5 inch x 1.8752 inch x 0.1875 inch) have the advantages of Extremely compact, lightweight design, composite load-bearing capacity, high rigidity, and flexible installation, and are therefore widely used in the Robotics, aerospace, semiconductor equipment, medical instruments and optoelectronic turntables.

The NAA15XL0 Thin-section four-point contact ball bearings are mainly composed of a thin-walled inner ring, a thin-walled outer ring, steel balls, and a cage. The raceway has a Gothic arch shape, and the steel balls form four-point contact with the inner and outer rings. The cross-sectional dimensions are constant and extremely thin.
Thin-section four-point contact ball bearings utilize a thin-walled constant cross-section design, resulting in lightweight construction and a small footprint. A single bearing can simultaneously withstand radial loads, bidirectional axial loads, and overturning moments. They possess high rigidity, high-speed capability, and are easy to install, making them a viable replacement for traditional combined bearings.
