The S71903 ACB/HCP4ADGA is a super precision angular contact ball bearing, measuring 17mm by 30mm by 14mm, crafted from high-quality chrome steel and ceramic balls. It handles radial loads up to 994 lbf and spins at remarkable speeds of 85,000 RPM, thanks to its phenolic cage and grease lubrication.
Its 25° contact angle and sealed design ensure smooth operation under angular loads, while the universal matching feature allows flexible arrangements like back-to-back or face-to-face. The extra-light preload (Class A) enhances precision in demanding applications.
This bearing excels in high-speed scenarios like machine tool spindles or dental equipment, where accuracy and low friction are crucial. It operates reliably in temperatures from -30°C to 110°C.
Weighing just 0.03kg, it’s lightweight yet robust, and comes in a matched set of two for balanced performance. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for easy replacements.
