The B8-85D-2RS is a specialized, compact single-row deep groove ball bearing designed to deliver reliable, high-speed performance in constrained automotive and small machinery spaces. Distinct from standard unsealed miniature bearings, this unit features premium double rubber contact seals (2RS) that form an impermeable barrier against road dust, moisture, and debris, while effectively retaining the internal lubricant. With its precise metric footprint—an 8 mm bore, 23 mm outer diameter, and a customized 14 mm width—the B8-85D-2RS is a critical component for automotive alternators, car generators, and high-efficiency electric motors.
