Super Precision Angular Contact Ball Bearings S71915 CE/HCP4ADT

Super Precision Angular Contact Ball Bearings S71915 CE/HCP4ADT

The S71915 CE/HCP4ADT is a super precision angular contact ball bearing with a 75mm bore and 105mm outer diameter, crafted from durable chrome steel and ceramic balls. It handles radial loads up to 8190 lbf and reaches speeds of 28,000 RPM, making it suitable for high-performance applications.

Its sealed design and grease lubrication ensure low maintenance, while the phenolic cage enhances durability. The 15° contact angle and matched arrangement (2 bearings << DT) provide excellent stability under angular loads. This bearing operates smoothly in temperatures from -30°C to 110°C and meets the P4A tolerance class for precision. Ideal for machine tools, spindles, or other high-speed equipment requiring accuracy. Weighing 0.59kg, it’s a robust yet lightweight solution. Interchangeable with SKF bearings, it offers a reliable replacement option.
