Tearing at clamp edges is a stress concentration failure, not a material defect. It typically occurs when the sleeve is installed with an incorrect installation gap, exposed to high-frequency dynamic shear, or clamped against a sharp edge. SOSHH prevents this through HF-welded exterior pockets and a polymer snap-band that distributes load evenly around the circumference. Provide your vibration frequency, stroke and installation gap so we can specify the correct sleeve for your sifter.
