SPIROL Introduces New Precision Machined Compression Limiters to Protect Plastic Assemblies

SPIROL is pleased to introduce the new Series CL6000 lightweight, lead-free, Aluminum Precision Machined Compression Limiters. Compression Limiters are designed to reinforce high stress joints in plastic assemblies where bolts are used to connect two components to each other.

Alignment Dowels & Bushings

SPIROL offers (3) different options for Alignment Dowels/Bushings – each one designed to simplify the assembly process and reduce the overall cost of manufacturing. The spring-type design of the DB100 Dowel Bushings and SD200 Spring Dowels offers substantial cost savings over inflexible alignment options as the flexible diameter allows for a larger hole tolerance and thus eliminates the need to precision hone the hole. When more exacting alignment is required, a precision-honed hole is required along with a precision Ground Dowel. SPIROL offers the series GD100 Ground Hollow Dowel that meets precision alignment requirements with significant weight savings over a solid equivalent.

SPIROL also designs and manufactures Installation Equipment, from manual to fully automatic modules. Learn more about SPIROL’s Installation Equipment, or contact us for support in determining the best dowel or bushing for your alignment application.

dowel bushing
DB100 Dowel Bushings
SPIROL Series DB100 Dowel Bushings are used to locate components in conjunction with bolts which pass through the inside diameter of the dowel after it has been installed. The flexible diameter absorbs wide hole tolerances, and the need for two separate holes (one for the alignment/locating pin and one for the bolt) is eliminated. The hardened Dowel Bushings also absorb shear loads, isolating the bolts from these forces.
spring dowel
SD200 Spring Dowels
The Series SD200 Spring Dowels are used to accurately locate components with respect to each other. They are formed around arbors to assure roundness. It is recommended that one half of the hole tolerance be used for the fixed location of the Spring Dowel and one half for the hole in the mating part.
ground hollow dowel
GD100 Ground Hollow Dowels
For applications requiring precision alignment, SPIROL’s Series GD100 Ground Hollow Dowels were designed to be direct replacements for the ISO 8734 Solid Dowels. The GD100 has precision ground outside diameter and maintain critical alignment within 20µm, and the roll formed design yields substantial cost and weight savings over Solid Dowels. The GD100 Ground Hollow Dowel is ideally suited for applications where centerline tolerance is a challenge, or where precision alignment of gears and components is critical.
