FAG Super-Precision Bearings Guide
Product Description
The HC71910-E-T-P4S super precision spindle bearing consists of an inner ring, outer ring, ceramic balls, and a laminated fabric cage. Its hybrid design combines ceramic balls with steel rings, providing low friction, reduced heat generation, and excellent 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 HC71910-E-T-P4S bearing is suitable for machine tool spindles, machining centers, grinding machines, precision milling equipment, and other high-accuracy machinery. Its high running accuracy, low heat generation, axial rigidity, and excellent speed capability provide reliable performance in demanding precision applications.
