FAG Super-Precision Bearings Guide
Product Description
The XC7021-E-T-P4S super precision spindle bearing consists of Cronidur steel inner and outer rings, ceramic balls, and a laminated fabric cage. Its hybrid design combines high-performance Cronidur steel rings with ceramic balls, providing excellent wear resistance, low friction, reduced heat generation, and high-speed capability. The 25° contact angle provides high axial rigidity and load capacity, while the P4S precision class ensures high running accuracy and stable performance.
The XC7021-E-T-P4S bearing is suitable for machine tool spindles, machining centers, grinding machines, precision milling equipment, and other high-performance machinery. Its high running accuracy, wear resistance, low heat generation, and axial rigidity provide reliable performance in demanding high-speed and precision applications.
