L10WA404 Bore 4.25 Inch, Imperial Open Type C, Radial Contact Ball Bearings
The L10WA404 Thin-section deep-groove ball bearings are primarily used in applications where space is limited, weight reduction is required, and loads are moderate. Typical applications include industrial robots (such as joints and end-effectors), semiconductor manufacturing equipment, medical imaging equipment (CT scanner gantries), optical trackers, radar antennas, packaging machinery spindles, and lightweight aerospace transmission mechanisms. They are capable of supporting both radial and bidirectional axial loads.
The L10WA404 bearing is a Inch Open Type C Radial Contact Ball Bearings with an inner diameter of 4.25 inch , an outer diameter of 6.25 inch, a width of 1 inch. It typically uses ISO Class NORMAL / ABEC-1 grade precision tolerances and AISI 52100 Steel rings, AISI 52100 Steel rolling mlement. Its dynamic radial rated load is approximately 6060 N, its static radial rated load is approximately 8210 N. Open (No seal) type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.

The L10WA404 Thin-section deep groove ball bearings mainly consist of a thin-walled inner ring, a thin-walled outer ring, steel balls, and a cage. Their cross-sectional dimensions are constant and extremely thin, typically conforming to ISO 12240 standards, and are available in open or sealed configurations.
Thin-section deep groove ball bearings utilize a thin-walled constant cross-section design, resulting in lightweight construction and a small footprint, significantly reducing the overall weight and size of equipment. They can simultaneously withstand radial and bidirectional axial loads, exhibiting low friction and high-speed characteristics, and are easy to install, making them suitable for light to medium load conditions.
