Compression limiters are unthreaded inserts for plastic reinforcement, used as reinforcing bushings in plastic housings to increase resistance to the tightening of screws and bolts.
The CL8000 compression limiters are precision machined from 360 brass.
Similar to the CL6000 aluminum series these limiters are suitable for both press-in and mold-in applications, including highly automated assembly processes. The precision-machined inner diameter ensures accurate seating on the core pin during molding, while the pilot design allows the part to stand freely in the hole before press-in installation. Once installed, the knurled surface provides secure retention within the plastic housing.
Applications for brass and aluminum compression limiters are generally the same; however, due to the lower yield strength of brass, the CL8000 features a thicker wall to accommodate the same class/grade bolt. While this increases the overall size and weight compared to the CL6000, it also provides a larger bearing surface for the mating component.
The most common reason to choose the CL8000 is for applications requiring a material more noble than aluminum on the galvanic series chart, making brass the preferred option in certain environments.
The CL8100 version is identical to the CL8000, with the addition of a head. This design offers extra bearing surface on the mating component, particularly useful when a flanged bolt or washer is not used.
The CL8000 and CL8100 series are rated for use with bolts up to ISO Class 10.9 and are available in diameters ranging from M3 to M10. Inch sizes and special lengths are available upon request.
