Details

SKF QJ 228 N2MA/C3 is a four point contact ball bearing with inner diameter 140 mm, outer diameter 250 mm and width 42 mm. Additional specifications include bore type CYLINDRICAL, cage STANDARD and lubrication STANDARD.

Four-point contact ball bearings with locating slots can accommodate high axial loads in both directions and small radial loads. They can operate at very high speeds and are more suitable than deep groove ball bearings for supporting large axial forces. The outer ring, with ball and cage assembly, can be mounted separately from the two inner ring halves. The locating slots can be used to prevent the outer ring from rotating. Features are : High-speed capability, Accommodate high axial loads in both directions and small radial loads, Require considerably less axial space than double row angular contact ball bearings, The locating slots can be used to prevent the outer ring from rotating. Applications : Pumps and compressors, Industrial gearboxes, Heavy machinery, Vertical shafts, Robotics and automation. N2 : Two Locating Slots (Notches), 180° Apart, In The Large Outer Ring Side Face, MA : Machined Brass Cage Guidance By The Outer Ring, C3 : Internal Clearance Larger Than Normal.
