The SKF 6309-2RS1\/C3 is a single row deep groove ball bearing with a 45 mm bore, 100 mm outside diameter and 25 mm width, fitted with a contact rubber seal on both sides (2RS1) and C3 radial internal clearance. It belongs to the SKF Explorer performance class and, per SKF, carries a basic dynamic load rating of 55.3 kN and a basic static load rating of 31.5 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; 09<\/strong> = bore code for 45 mm (09 x 5); 2RS1<\/strong> = contact seals on both sides; C3<\/strong> = radial internal clearance greater than normal.<\/p>\n

The contact seals rub lightly on the inner ring, which keeps grease in and dust, water and washdown spray out better than a shield. The price of that protection is speed: SKF lists a limiting speed of 4,500 r\/min for this sealed version, against 7,500 r\/min for the shielded 6309-2Z\/C3.<\/p>\n
