Product Description

The XC71911-EDLR-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 Direct Lube design supplies lubricant directly to the rolling contact area for efficient lubrication and stable operation at high speeds.

The XC71911-EDLR-T-P4S bearing is suitable for machine tool spindles, high-speed machining centers, grinding machines, precision milling equipment, and other high-performance machinery. Its high running accuracy, efficient lubrication, wear resistance, and low heat generation provide reliable performance in demanding high-speed and precision applications.
