The 100BNR10HTDUELP4Y is a super-precision hybrid angular contact ball bearing from NSK's ROBUST series. It features a 100 mm bore, 150 mm outside diameter, and ceramic silicon nitride balls paired with SUJ2 steel rings for reduced weight and enhanced thermal properties. Supplied as a duplex universal matched set with 18° contact angle, extra light preload, and ISO Class 4 (ABEC 7) precision with phenolic resin cage.
Super-precision angular contact ball bearings are designed for high-speed machine tool spindles, precision grinding equipment, and aerospace applications where rigidity, accuracy, and thermal stability are critical. The duplex universal arrangement permits flexible mounting configurations (back-to-back, face-to-face, or tandem) to accommodate different load and stiffness requirements.
