Performance Features
71803 AC P4A GA angular contact ball bearing is engineered for high-precision and high-performance applications. Its P4A precision grade ensures ultra-tight tolerances, meeting the stringent requirements of precise machinery. With a 25° contact angle (AC), it can handle radial and axial loads simultaneously, stable high-speed operation, and provides self-lubrication for energy efficiency. Made from premium heat-treated bearing steel, it offers enhanced rigidity for accurate performance under heavy loads, an extended service life, and reliable operation across a wide temperature range, making it ideal for aerospace, semiconductor, and other precision industrial systems.
High-Speed Equipment: Centrifuges and drilling/milling machinery, suitable for scenarios up to 18,000 RPM
High precision, high-speed stability, resistance to combined loads, and long service life make it a critical component in cutting-edge fields like semiconductors, aerospace, and healthcare.
