Super Precision Angular Contact Ball Bearings S7026 ACD/HCP4ADGB

Super Precision Angular Contact Ball Bearings S7026 ACD/HCP4ADGB

The S7026 ACD/HCP4ADGB is a super precision angular contact ball bearing with a 130mm bore and 200mm outer diameter, designed for high-speed applications. It features a 25° contact angle and comes sealed for protection, with universal matching for flexible arrangement options.

Made from chrome steel rings and ceramic balls, it handles dynamic radial loads up to 51525 lbf and spins smoothly at 11000 RPM. The phenolic cage ensures durability, while the light preload (Class B) reduces friction.

Its sealed design keeps grease in and contaminants out, making it low-maintenance. Ideal for machine tools or high-precision spindles where accuracy and speed are key.

Weighing 5.38kg, this bearing is robust yet efficient. It’s interchangeable with SKF models and works in temperatures from -30°C to 110°C. The set includes two bearings for versatile mounting (back-to-back, face-to-face, or tandem).
