The FPAB108 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.
