Super Precision Angular Contact Ball Bearings 7005 ACE/HCP4AL1DT

Super Precision Angular Contact Ball Bearings 7005 ACE/HCP4AL1DT

The 7005 ACE/HCP4AL1DT is a super precision angular contact ball bearing with a 25mm bore and 47mm outer diameter, crafted from durable chrome steel and ceramic balls. It handles radial loads up to 2858 lbf and spins smoothly at speeds up to 75,000 RPM.

Its 25° contact angle and matched pair design (2 bearings << DT) provide excellent stability for angular loads, while the phenolic cage ensures quiet operation. The open seal allows easy lubrication and maintenance. This bearing is ideal for high-speed applications like machine tool spindles or precision instruments, operating in temperatures from -30°C to 110°C. With a P4A tolerance class, it offers reliable performance for demanding setups. Weighing just 0.13kg, it’s lightweight yet robust. Interchangeable with SKF bearings, it’s a practical choice for replacements or upgrades. The preload option adds versatility for fine-tuning performance.
