Super Precision Angular Contact Ball Bearings S71916 ACE/HCP4ADBA

Super Precision Angular Contact Ball Bearings S71916 ACE/HCP4ADBA

The S71916 ACE/HCP4ADBA is a super precision angular contact ball bearing with an 80mm bore and 110mm outer diameter, crafted from durable chrome steel. Its compact 32mm width makes it suitable for tight spaces, while the ceramic balls enhance performance.

This bearing handles radial loads up to 7898 lbf and reaches speeds of 28,000 RPM, thanks to its phenolic cage and grease lubrication. The 25° contact angle ensures smooth operation under angular loads.

Sealed for protection, it comes as a matched set of two bearings (DB arrangement) with extra light preload. Ideal for high-speed applications like machine tool spindles or precision equipment.

Operating between -30°C and 110°C, it meets P4A tolerance standards for accuracy. Weighing 0.62kg, it balances strength and lightweight design.
