Super Precision Angular Contact Ball Bearings S71909 CE/HCP4ADBA

Super Precision Angular Contact Ball Bearings S71909 CE/HCP4ADBA

The S71909 CE/HCP4ADBA is a super precision angular contact ball bearing with a 45mm bore and 68mm outer diameter, crafted from chrome steel for durability. Its 15° contact angle and ceramic balls ensure smooth operation under radial loads up to 3780 lbf.

This sealed unit comes pre-greased and can handle speeds up to 46,000 RPM, making it ideal for high-performance applications. The phenolic cage adds stability, while the extra-light preload (Class A) reduces friction.

Designed as a matched pair (DB arrangement), it offers precise alignment for demanding setups. Suitable for CNC spindles or precision tools where accuracy is key.

Weighing 0.23kg, it operates in temperatures from -30°C to 110°C. Compliant with P4A tolerance standards for reliable performance. Interchangeable with SKF bearings for easy replacement.
