The SKF 6301-2Z\/C3 is a single row deep groove ball bearing with a 12 mm bore, 37 mm outside diameter and 12 mm width, fitted with a non-contact metal shield on both sides (2Z) and C3 radial internal clearance. It belongs to the SKF Explorer performance class and, per SKF, carries a basic dynamic load rating of 10.1 kN and a basic static load rating of 4.15 kN.<\/p>\n

The designation can be read directly: 6<\/strong> = single row deep groove ball bearing, 3<\/strong> = ISO dimension series 03 (medium), a heavier cross-section with larger balls for higher loads on the same shaft size; 01<\/strong> = bore code for 12 mm; 2Z<\/strong> = shields on both sides; C3<\/strong> = radial internal clearance greater than normal.<\/p>\n

Shields leave a narrow gap to the inner ring, so friction stays low and SKF lists a limiting speed of 22,000 r\/min for this version, compared with 14,000 r\/min for the sealed 6301-2RSH\/C3. That makes the 2Z design the usual choice for electric motors, fans and other clean, fast-running positions.<\/p>\n
