Super Precision Angular Contact Ball Bearings S71914 ACD/HCP4ADT

Super Precision Angular Contact Ball Bearings S71914 ACD/HCP4ADT

The S71914 ACD/HCP4ADT is a super precision angular contact ball bearing with a 70mm bore and 100mm outer diameter, crafted from durable chrome steel and ceramic balls. It handles radial loads up to 11858 lbf and reaches speeds of 28000 RPM, making it suitable for high-performance applications.

Its sealed design and grease lubrication ensure low maintenance, while the phenolic cage offers excellent durability. The 25° contact angle and matched arrangement (2 bearings << DT) provide stability under angular loads. This bearing operates smoothly in temperatures from -30°C to 110°C and meets P4A tolerance standards for precision. Ideal for machine tools, spindles, or other high-speed equipment requiring accuracy. Weighing 0.57kg, it’s a robust yet lightweight solution. Interchangeable with SKF bearings, it’s a reliable choice for replacements or upgrades.
