The SKF 6319-2RS1 sealed deep groove ball bearing is engineered for substantial shaft support in industrial equipment where a 95mm bore and high load-carrying capability are essential. Its 200mm outside diameter and 45mm width provide a robust bearing arrangement for machinery exposed to sustained mechanical loading. SKF Explorer specifications give a basic dynamic load rating of 159kN and a basic static load rating of 118kN, making these values important considerations when assessing operating loads, fatigue life and stationary loading conditions. The single row deep groove raceways primarily accommodate radial forces while also supporting axial loads in both directions within the bearing's rated limits. Compared with the corresponding 6219 series, the 6319 has a larger outside diameter and wider cross-section, so the two bearings are not dimensionally interchangeable.
The 2RS1 rubber contact seals retain factory-applied grease and help restrict the entry of dust, moisture and other contaminants. This protection is useful in large drive systems where bearing access is limited and unexpected maintenance can interrupt production. SKF specifies a limiting speed of 2,200rpm for this contact-sealed configuration; actual continuous operating suitability must also account for temperature, lubrication, load and seal friction. Normal (CN) radial internal clearance distinguishes this bearing from the 6319-2RS1/C3 variant, which has greater initial clearance. Correct shaft and housing fits are especially important on large bearings because interference mounting and thermal expansion can affect operating clearance. When replacing an existing unit, verify the complete designation, sealing arrangement and dimensions before installation.
Typical Applications:
Heavy-duty industrial electric motors
