SKF cam followers (stud-type track rollers) are designed to run on all types of tracks and to be used in cam drives, conveyor systems, etc. They are based on either needle (fig. 1) or cylindrical (fig. 2) roller bearings. Instead of an inner ring, they have a threaded solid stud (pin). SKF supplies them ready-to-mount. They are available in several designs and variants:

• With or without a cage
• With different stud designs:
  • A concentric seat
  • An eccentric collar
• With several sealing solutions
• With the outer ring running surface profile:
  • Crowned as standard
  • Cylindrical (flat)

In contrast to ball and roller bearings, where the bearing size refers to the bore diameter d, for cam followers the size refers to their outside diameter D.

Features and benefits

• Accommodate high radial loads
  The thick-walled outer ring enables high radial loads, while reducing distortion and bending stresses.
• Accommodate axial loads
  The integral flange (stud head) and the pressed-on flange ring enable cam followers to accommodate axial loads that can occur because of skew or tilting.
• Long service life
  The crowned outer ring running surface is beneficial for applications where outer ring tilting relative to the track may occur or where edge stresses need to be minimized.
• Easy to mount
  The threaded solid stud (pin) of cam followers can be quickly and easily attached to appropriate machine components by means of a hexagonal nut.
