SD200 DB100 Dowel Bushing Ground Hollow Dowels

alignment dowels/ bushings/ locating bushings/ ground hollow dowels - DB100/SD200/GD100

Alignment Dowels/Bushings are used to locate components with respect to each other. For Dowel Bushings applications, the hollow design permits a fastening screw or bolt to pass through the inside diameter eliminating the need to drill a separate hole.

If components are located or positioned by methods other than the dowel itself, and the issue is to allow for disassembly and then re-assembly with the components in exactly the same location – then it is recommended that the components be drilled together and the dowel installed in the assembled condition. During disassembly, the dowel may be removed and reinstalled during re-assembly. This method eliminates the need for hole tolerancing and hole centerline concerns. It provides for very accurate permanent locating.

Features and Benefits as follows.

Spring action – The diameter of the bushing is slightly larger than the hole. The spring action of the Bushing allows it to be installed into a drilled or cored hole and assume the diameter of the hole. It is self-retained once installed.

Staggered seam - The staggered seam prevents interlocking, making these Bushings suitable for automatic feeding and eliminating the need to separate them during manual assembly.

Lead-in chamfers - The beveled chamfer around the entire periphery of the Bushing is designed to facilitate ease of insertion and to avoid skiving of the Bushing during installation.

Controlled inside diameter - The inside diameter of the Dowel Bushings is designed to provide clearance for a bolt through the Bushing for the purpose of fastening the aligned components together. This isolates the bolt from the shear loading and increases the joint integrity. It also eliminates the cost of a separate hole.

The more common application is to use the Dowels to fix the relative location of two or more components. In this situation, the Dowels are partially installed in one component, the initial installation, and then holes in the mating component are pushed over the exposed end of the partially installed Dowel. The following factors need to be considered for precision location:

Hole dimension tolerance

Relative depth of initial installation

Total length of the Dowel

True position of hole centerlines
