CSXF350 Bore 35 Inch, Imperial Open Type X, 4-Point Contact Ball Bearings
The CSXF350 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 CSXF350 bearing is a Inch Open Type X 4-Point Contact Ball Bearings with an inner diameter of 35 inch , an outer diameter of 36.5 inch, a width of 0.75 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 14100 N, its static radial rated load is approximately 40350 N. Its dynamic axial rated load is approximately 116627 N, its static axial rated load is approximately 448803 N. Open (No seal) type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.

The CSXF350 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.
