The FAG HC7018-C-T-P4S-UL is a high-precision hybrid angular contact ball bearing designed for demanding applications requiring high speeds and rigidity. Featuring ceramic balls (silicon nitride) and bearing steel rings, this bearing offers superior performance, reduced friction, and extended service life compared to traditional steel bearings. It has a 15° contact angle (C) and a textile laminate cage (T), guided on the outer ring. The P4S tolerance class ensures exceptional running accuracy, while the UL designation indicates a universal arrangement for paired mounting with a light preload, making it ideal for machine tool spindles and other high-speed rotating equipment. With an inner diameter of 90 mm, an outer diameter of 140 mm, and a width of 24 mm, it is engineered for precision.
