L15VA2500 Bore 25 Inch, Imperial Open Type A, Angular Contact Ball Bearings
The L15VA2500 Thin-section angular contact ball bearings are primarily used in applications with stringent requirements for weight, space, and precision, such as aerospace gyroscopes, robotic joints, medical CT scanner gantries, machine tool spindles, semiconductor manufacturing equipment, optical instruments (e.g., telescopes), and precision rotary tables.
The L15VA2500 bearing is a Inch Open Type A Angular Contact Ball Bearings with an inner diameter of 25 inch , an outer diameter of 26.5 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 9585 N, its static radial rated load is approximately 34700 N. Its dynamic axial rated load is approximately 116093 N, its static axial rated load is approximately 445690 N. Open (No seal) type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.

The L15VA2500 Thin-section angular contact 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, with contact angles typically of 15°, 25°, or 30°, making them suitable for space-constrained installations.
Thin-section angular contact ball bearings utilize a thin-walled, constant cross-section design, resulting in lightweight construction and a small footprint, effectively reducing the overall weight of equipment. They can simultaneously withstand radial and axial loads, possessing high rigidity, high-speed capability, and good positioning accuracy, and are easy to install.
