COMPRESSION LIMITERS SPIROL® CL220 Split Seam Compression Limiters The Series CL220 Split Seam Compression Limiter is installed into a hole after the moulding process. The spring force generated during installation provides self-retention in the assembly. The flexible diameter accommodates wide hole tolerances, and the gap is designed such that the parts will not interlock in the free state. Once installed, the CL220 provides a minimum clearance of 1mm over the bolt diameter to compensate for misalignment. The CL220 is the only standard Compression Limiter finished with a protective coating of ArmorGalv®. 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. What is ArmorGalv®? ArmorGalv® is a zinc alloy thermal diffusion coating covered by ASTM A1059M-08(2013) that provides uniform deposition of coating on all surfaces of the part. There are no insignificant surfaces and the entire inner diameter receives full coating and protection. ArmorGalv® offers a minimum of 1,000+ hours corrosion resistance to red rust, and is an ideal coating for some of the most aggressive environments such as marine, automotive, agricultural, mining and industrial manufacturing. Additional benefits include: • ZERO risk of hydrogen embrittlement • Will not reduce fatigue strength of material • Uniform deposition of coating on all surfaces • Anti-galling characteristics similar to cadmium • No flaking, peeling, or blistering • Hard and highly abrasion resistant @ 37-42 HRC • Slightly porous surface will retain paint and other coatings ArmorGalv® Coated INCOMPLETE I.D.
