Flexible Shaft Coupling Spider

Positioned between metal hubs in rotary drive systems, these elastomeric spiders absorb torsional shock and compensate for minor shaft misalignment. The radial lobes are designed to interlock with mating jaws, creating a flexible connection that dampens vibration and protects downstream components from impact loads during operation.

The symmetrical geometry requires consistent wall thickness and uniform lobe spacing to ensure balanced torque transmission and prevent premature fatigue failure. Precision injection molding controls the dimensional stability of the central bore and outer profile, maintaining tight tolerances that guarantee smooth engagement without binding or excessive play in the assembly.

Material selection focuses on high-performance thermoplastics such as PA66, POM, or specialized engineering grades like PEEK to meet specific requirements for wear resistance, temperature stability, and chemical compatibility. Our facility utilizes Fanuc and Engel injection molding machines alongside ISO 9001 and IATF 16949 certified processes to deliver consistent quality for both prototyping and volume production runs.

Submit detailed drawings specifying lobe count, durometer hardness (if applicable), and critical interface dimensions to initiate the quoting process. We evaluate mold complexity and material availability to provide accurate lead times, supporting customized solutions for industrial machinery, automotive drivetrains, and precision motion control applications.
