Let SPIROL help you choose which is best for your application.  Our hollow dowels provide:

  • Precision alignment
  • Lead-in chamfers to ease insertion
  • Alignment solutions that are 50% lighter and 30% less expensive than solid dowels

SPIROL® Series DB100 Dowel Bushings, Series SD200 Spring Alignment Dowels, and Series GD100 Ground Hollow Dowels 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.

Ground Hollow Dowels are used where centerline tolerancing and precision alignment are required. They are designed to be direct replacements for standard Ground Solid Dowels per ISO 8734 for alignment applications.

Here are the specifications for the DB100 Dowel Bushings and SD200 Spring Alignment Dowels. Here are the specifications of the GD100 Ground Hollow Dowels.
