SPIROL is pleased to introduce the new Series CL6000 lightweight, lead-free, Aluminium 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. They protect the plastic from excessive compression by absorbing the load when the bolt is tightened to the recommended tightening torque. This ensures the durability and reliability of the joint throughout the product's lifespan.

The CL6000 is machined from 2024 grade aluminium which provides the best combination of strength, corrosion resistance, machineability and cost. The CL6000 aluminium Compression Limiters are 40% stronger and 1/3 the weight of the same Compression Limiter manufactured from brass.

For applications that require extra bearing surface for the mating component, the CL6100 Headed Compression Limiter has all of the same features of the CL6000, with the addition of a head. In addition, for applications that require a galvanic alternative to aluminium, SPIROL is simultaneously launching the new CL8000 brass precision machined Compression Limiters, as well as the CL8100 headed brass version.

SPIROL offers several different standard types of Compression Limiters to meet specific application requirements and assembly methods. The current Series CL600 & CL800 lines of machined Compression Limiters are being replaced with the enhanced CL6000 and CL8000 based on the following benefits:

Precision: Enhanced control of critical features and better geometric dimensioning and tolerancing make this series ideal for highly automated or moulded-in assembly processes.

Retention: Superior knurl formation and control result in more consistent and robust retention performance in post-mould assembly processes.

Product Range: Larger selection of standard products to meet expansive application requirements and preferences.

The new standard Precision Machined Compression Limiters are available in a wide range of standard sizes, in both aluminium and brass, and in headed and non-headed configurations.
