Ground Hollow Dowels suit precision alignment applications.

Press Release Summary:

Series GD100 Ground Hollow Dowels are manufactured from strip steel and are OD ground to achieve tight diameter tolerances that enable alignment up to 20 µm. Offered in standard diameters of 8, 10, 12, and 16 mm, dowels can be case-hardened for wear resistance or manufactured from heat treated, high carbon steel for greater shear strength.

SPIROL Introduces New Ground Hollow Dowel for Precision Alignment Applications

Danielson, CT - SPIROL International Corporation is pleased to announce the release of a new innovative lightweight product to achieve precision alignment. SPIROL's new Series GD100 Ground Hollow Dowels are designed to be a direct replacement for Ground Solid Dowels manufactured per ISO 8734 when used in alignment applications. The Series GD100 is manufactured from strip steel, and then OD ground to achieve extremely tight diameter tolerances that enables critical alignment up to 20 µm. The main advantage of the new GD100 Ground Hollow Dowel is that one can achieve the same alignment as with Ground Solid Dowels with a substantial reduction in cost. In most scenarios, the GD100 Ground Hollow Dowel is at least 30% less expensive. In addition, the weight of the Hollow Dowel is approximately 50% less. This translates into lighter assemblies, and a significant cost savings over Ground Solid Dowels. The Series GD100 supplements SPIROL's Coiled Pins and Alignment Bushings that are also used for alignment. This new precision line is offered in four standard diameters: 8, 10, 12 and 16mm. Special sizes can be designed upon request. When required, the GD100 line can be case hardened for wear resistance, or manufactured from heat treated, high carbon steel for improved shear strength. Take advantage of SPIROL's complimentary Applications Engineering support on your next alignment application. SPIROL Engineers will review your application needs and work with your design team to recommend the best solution at the lowest total installed cost. It all starts with our Optimal Application Engineering process.
