Super Precision Angular Contact Ball Bearings S71913 ACE/P4ADBC

Super Precision Angular Contact Ball Bearings S71913 ACE/P4ADBC

The S71913 ACE/P4ADBC is a super precision angular contact ball bearing with a 65mm bore and 90mm outer diameter, crafted from high-quality chrome steel. It handles both radial and angular loads, with a dynamic radial load capacity of 5738 lbf. The sealed design keeps grease in and contaminants out, ensuring smooth operation.

With a 25° contact angle and moderate preload, this bearing offers excellent stability for high-speed applications. It can reach speeds up to 31,000 RPM and operates in temperatures from -30°C to 110°C. The phenolic cage adds durability while reducing friction.

This matched set of two bearings (DB arrangement) is ideal for precision machinery like spindles or CNC equipment. Its P4A tolerance class ensures tight performance standards. Weighing 0.4kg, it’s a robust yet manageable component for demanding setups.

Interchangeable with SKF bearings, it’s a reliable choice for replacements or upgrades. The grease lubrication makes maintenance straightforward, while the sealed design extends service life in challenging environments.
