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.

SPIROL Expands CL220 Split Seam Compression Limiter Line 3-MAR-2023

SPIROL has expanded the CL220 Compression Limiter offering by adding additional diameter and length combinations to accommodate a variety of application requirements.

The CL220 Compression Limiter’s split-seam, flexible diameter accommodates wide hole tolerances and the gap is designed such that the parts will not interlock in the free state. The CL220 Compression Limiter is intended to be installed into the plastic component after the molding process, and it is spring force that provides self-retention within the hole. Once installed, the CL220 provides a minimum clearance of 1mm around the bolt diameter to compensate for misalignment.

Produced from high carbon steel, the CL220 is finished with a protective coating of ArmorGalv®, a zinc alloy thermal diffusion coating complimented with two sealers that provides 1000+ hours of salt spray protection for highly corrosive applications such as automotive, marine, mining and industrial manufacturing. Additional benefits of ArmorGalv® include no insignificant surfaces as the entire inner diameter (ID) of the Limiter receives full coating and protection.

Rated for use up to ISO Class 8.8 bolts, the CL220 Compression Limiter offers the widest range of standard diameter and length combinations to accommodate a variety of application requirements.
