Suited for a wide range of applications, LOCTITE® retaining compounds increase the reliability of cylindrical fittings like bearing on shaft.

To find the ideal Loctite for securing cylindrical fittings, just answer three whats:

  • 1 Diametrical clearance
  • 2 Shear strength
  • 3 Temperature resistance
