Dynamic Load Rating: 122 kN (27,400 lbf). Static Load Rating: 93 kN (20,900 lbf). Limiting Speed: 3,800 rpm. Operating Temperature: -30 °C to 120 °C. Item Weight: 6.94 lb. Material: Bearing Steel. Manufacturer: Nachi-Fujikoshi.
A deep groove ball bearing takes radial load with moderate thrust in either direction. P5 tolerance tightens bore, outside diameter and raceway runout. Straight bore for a direct shaft seat. Open faces take grease or oil from the surrounding housing.
Cross-references: SKF 6220/P5 and FAG 6220-P5, both on the same 100 x 180 x 34 mm envelope at the same precision class. The standard-tolerance 6220 shares the envelope and is a related size at a looser running accuracy.
100 mm bore, 180 mm outside diameter, 34 mm width.
