Spring Alignment - Dowels and Bushings

 

Dowels and Bushings Thread-Rite Screw Company Chicago ILSpirol's roll formed hardened bushing are designed to meet one or more of the following objectives:

  • Align mating components,
  • Eliminate drilling of a separate bolt hole,
  • Protect bolts from shear loading, and/or
  • Maintain joint integrity

Although these hollow, lightweight bushings are not precision ground and do not require precision holes, thus saving in component and hole preparation costs, they are capable of precision alignment if the design guidelines are followed. Further savings can be achieved by using the inside of the dowel bushing for the bolt and thus eliminating the cost of a separate bolt hole. The design concept also protects the bolt from shear loads perpendicular to the bolt and isolates the forces on the bolt to tension loading. Shear forces acting on a bolted joint cause the joint members to slip back and forth, which causes the bolts and nuts to rotate, reducing the pre-load tension. This is particularly the case with short bolts with a reduced clamping distance.
