Product Name Notes
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.
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...
The CL220 Split Seam – Extra Clearance Compression Limiter is intended for postmold installation. The flexible diameter accommodates wide hole tolerances, while the seam is designed to prevent interlocking 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. This...
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...
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...
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...
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...
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...
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...
