RBC 7610 DLG TNT G 18 High-Precision Angular Contact Bearing | 50x80x16 mm | P4 Class
The RBC 7610 DLG TNT G 18 is a specialized single-row angular contact ball bearing engineered for extreme speed and rigorous precision requirements. Featuring a 50 mm bore, 80 mm outer diameter, and 16 mm width, this bearing utilizes the 'DLG' optimized internal geometry, typically signifying a light 15° contact angle. This specific geometry minimizes axial and radial deflection, making it ideal for maintaining shaft rigidity under high rotational loads. The inclusion of a Polyamide resin cage (TNT) ensures low mass, minimal friction, and excellent thermal stability necessary for continuous high-speed operation, while the G designation guarantees the bearing is dimensionally matched for universal pairing in duplex or triplex sets.
Designed to meet the stringent requirements of the machine tool industry, the Class 18 precision rating (equivalent to ABEC 7 or ISO P4) guarantees exceptional running accuracy and minimal total indicated runout (TIR). This makes the 7610 DLG TNT G 18 the definitive choice for critical applications such as high-speed CNC machine spindles, precision grinding machines, and industrial robotics. Selecting this RBC bearing ensures maximized spindle uptime, predictable preload control, and significantly extended service life compared to standard-grade bearings, directly enhancing overall equipment efficiency (OEE).
