Product Name Notes
Standard Oval Split Seam Compression Limiter -- Series CL400 Produced from high carbon steel, the oval Series CL400 accommodates up to 2.25mm extra clearance on one axis, providing additional flexibility over round Compression Limiters for centerline and stack-up tolerancing.
Standard Split Seam Compression Limiter -- Series CL350 Similar to the Series CL200 Compression Limiter, the CL350’s were designed with a thicker wall for increased bearing surface when clamped against soft mating materials. Generous bolt clearance also aids...
Standard Oval Molded-in Compression Limiter -- Series CL460 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. This...
Headed Aluminum Compression Limiter -- Series CL601
Headed Aluminum Compression Limiter -- Series CL601 - Inch
Headed Aluminum Compression Limiter -- Series CL601 - Metric
The CL601 headed aluminum Compression Limiter is the same as the CL600, with the addition of a head. The head provides extra bearing surface on the mating component when a...
Headed Brass Compression Limiter -- Series CL801
Headed Brass Compression Limiter -- Series CL801 - Inch
Headed Brass Compression Limiter -- Series CL801 - Metric
The CL801 headed brass Compression Limiters are the same as the CL800 with the addition of a head. Similar to the CL601, the head provides extra bearing surface on the...
Split Seam Compression Limiter -- Series CL200
Split Seam Compression Limiter -- Series CL200 - Inch
Split Seam Compression Limiter -- Series CL200 - Metric
The Series CL200 Compression Limiter is produced from high carbon steel and intended for post-mold installation. The spring force generated during installation provides self-retention in the assembly. The flexible diameter...
Standard Molded-In Compression Limiter -- Series CL500
Standard Molded-In Compression Limiter -- Series CL500 - Inch
Standard Molded-In Compression Limiter -- Series CL500 - Metric
The Series CL500 is produced from low carbon steel with a butted seam to prevent plastic from entering the inner diameter of the Compression Limiter during the molding process. This...
Aluminum Compression Limiter -- Series CL600
Aluminum Compression Limiter -- Series CL600 - Inch
Aluminum Compression Limiter -- Series CL600 - Metric
The Series CL600 is machined from 2024 aluminum as this grade provides the best combination of strength, corrosion resistance, machinability and cost. Additional advantages of aluminum are that it is...
Standard Brass Compression Limiter -- Series CL800
Standard Brass Compression Limiter -- Series CL800 - Inch
Standard Brass Compression Limiter -- Series CL800 - Metric
The Series CL800 is machined from 360 brass. Similar to the CL600, the CL800 can be molded in or pressed into an assembly. The applications for SPIROL’s brass and aluminum...
