NN3012-AS-K-M-P4 Super precision cylindrical roller bearings

NN3012-AS-K-M-P4 double row cylindrical roller bearings are suitable for high radial load scenarios and are commonly used in machine tool spindles, gearboxes, and other equipment. AS： The outer ring is equipped with lubrication grooves and oil holes to enhance high-speed performance and load-bearing capacity, K： Representing a conical hole (taper 1:12), it is convenient for installation adjustment and pre tightening force control, M： Machine cut brass retainer, P4： The accuracy level is P4 (ISO standard), with high rotational accuracy (radial runout ≤ 5 μ m). The NN30 series is suitable for precision machine tools or high-precision equipment.
