adjacent components cannot serve as centred (ig. 3 and ig. 4) The lange facilitates mounting and

For additional information, refer to Design
considerations, page 903 To accommodate combined radial and axial
loads, needle roller thrust bearings in the
AXW series can be combined with the
following radial needle roller bearings:
• drawn cup needle roller bearings with a
closed end or with open ends (ig. 6)
• needle roller bearings with machined
