中国Precision Alignment Dowels
Direct Replacements for ISO 8734 Dowel Pins
SPIROL’s GD100 Ground Hollow Dowels are designed to be direct replacements for Ground Solid Dowels manufactured per ISO 8734 when used in alignment applications. This innovative product is manufactured from strip steel, and then OD ground to achieve extremely tight diameter tolerances that enable critical alignment up to 20µm.
The main advantage of the GD100 Ground Hollow Dowel is its ability to achieve the same alignment as the Ground Solid Dowel with a significant reduction in cost due to its hollow construction. In most scenarios, the Ground Hollow Dowel is approximately 50% lighter and at least 30% less expensive than the solid equivalent.
If installation equipment is required, SPIROL also offers a standard comprehensive line of Installation Equipment from manual to fully automatic modules, with or without out fixturing, to support your assembly requirements.
Application Engineering Assistance: If you would like assistance in selecting the proper Alignment Dowel for your assembly, please Request Technical Support! We are here to help!
Dowel Bushings
SPIROL Series GD100 Ground Hollow Dowels provide precision alignment at a fraction of the cost of Solid Ground Dowels of the same size. GD100 Ground Hollow Dowels are manufactured from low carbon steel. When required, Ground Hollow Dowels can be case hardened for wear resistance or manufactured from heat treated, high carbon steel for improved shear strength. SPIROL's precision line of GD100 Ground Hollow Dowels is offered in five standard diameters: Ø6, Ø8, Ø10, Ø12 and Ø16mm. Depending on the application’s requirements, specials can be developed and manufactured with minimal investment.
