Super Precision Angular Contact Ball Bearings S71914 ACE/HCP4ADT

Super Precision Angular Contact Ball Bearings S71914 ACE/HCP4ADT

The S71914 ACE/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 7605 lbf and spins smoothly at high speeds up to 28,000 RPM.

Its sealed design keeps grease in and contaminants out, while the phenolic cage ensures quiet, long-lasting performance. The 25° contact angle and matched pair arrangement (2 bearings << DT) provide excellent stability for precision applications. This bearing is ideal for high-speed machinery like spindles or CNC tools, where accuracy and low friction are key. It operates reliably in temperatures from -30°C to 110°C and meets P4A tolerance standards for tight precision. Weighing 0.55kg, it’s a robust yet lightweight choice for demanding setups. The ceramic balls reduce wear and heat buildup, making it a smart pick for performance-focused systems.
