Barden Bearings SR8SS3 Precision Ball Bearing

Barden SR8SS3 G-2 Deep Groove Instrument Bearing is a shielded, single‑row precision ball bearing designed for instrument‑grade accuracy. It features a 1/2 in bore, 1-1/8 in outer diameter, and 1/4 in width, with SS guarding to resist contamination and a compact, one‑row configuration. The bearing uses 440C ball steel with a corrosion‑resistant retainer and shield, and is cataloged as SR8SS3/G2, indicating its G‑2 precision class. Its dynamic load rating is 3403 N and static rating 1543 N, making it suitable for precision instrumentation and small‑form‑factor machinery where low friction and rigidity are critical. Barden bearings are a recognized leader in super‑precision solutions, and the SR8SS family is noted for shielded, high‑accuracy performance in demanding metrology and instrumentation applications. This SR8SS3 variant embodies that design intent, offering reliable, compact bearing performance for environments where contamination is a concern and exacting tolerances matter.
