The SKF 6319-2Z metal shielded deep groove ball bearing is engineered for substantial rotating shafts operating under demanding industrial loads. Its 95mm bore, 200mm outside diameter and 45mm width provide a robust bearing arrangement for large motors, transmission equipment and machinery drive shafts. Compared with the smaller 6219 series, its larger cross-section offers significantly greater load-carrying capacity, provided the assembly can accommodate the increased housing diameter and width. Its single row deep groove raceways support predominantly radial loads together with axial forces in either direction, within the bearing's rated limits. SKF specifies a basic dynamic load rating of 159kN and a basic static load rating of 118kN, making accurate load calculations and proper shaft support important during selection.
The 2Z suffix identifies a non-contact metal shield on each side of the bearing. These shields help retain the factory grease and restrict the entry of larger particles without the rubbing contact associated with rubber contact seals. This supports relatively low-friction operation, although metal shields offer less protection against water and fine contamination than contact seals. The SKF 6319-2Z has a published limiting speed of 3,600rpm, subject to operating load, lubrication and temperature. Its normal (CN) radial internal clearance differs from the greater-than-normal clearance of the 6319-2Z/C3. This distinction matters where interference fits or operating temperatures reduce internal clearance. For replacement work, verify the complete designation, shield configuration and mounting dimensions before installation.
