SPIROL Introduces Oval Compression Limiters 1-SEP-2016

SPIROL is proud to announce the introduction of a standard line of Oval Compression Limiters to their suite of other Compression Limiters for plastic assemblies. The CL400 Press-In and CL460 Molded-In Oval Compression Limiters both accommodate up to 2.25mm extra clearance on one axis, providing additional flexibility over round Compression Limiters for centerline and stack-up tolerancing.

Series CL400 Oval Press-In: Produced from high carbon steel, this split-seam oval Compression Limiter is roll-formed, and spring tension provides positive retention in the hole. The roll-forming manufacturing method yields substantial cost savings over machined products with similar features and characteristics.

Series CL460 Oval Molded-In: The CL460 Series is similar to the oval Series CL400, but produced with a butted-seam so as to prevent plastic from entering the inner diameter during the molding process. Both are rated for use up to ISO Class 8.8 bolts.
