The FAG HCS71908-C-T-P4S-UL is a high-precision hybrid angular contact ball bearing designed for demanding spindle applications. Featuring a 40 mm bore, 62 mm outer diameter, and 12 mm width, this bearing incorporates ceramic balls (silicon nitride) for reduced friction, higher stiffness, and extended service life, particularly at high speeds. It has a 15° contact angle (C) and P4S precision class, making it suitable for universal pair mounting (UL). The textile laminate cage (T) further contributes to its high-speed capabilities, supporting dynamic loads up to 14.5 kN and static loads up to 8.3 kN, with limiting speeds of 30,000 rpm for grease lubrication and 45,000 rpm for oil-air lubrication.
