Single-point ratings at 0° and 90°, with the ring aligned with the load. Not suitable for rotation under load. Consult the manufacturer above +200 °C.
Data apply to the identified reference configuration, not to every product of the same size. Confirm supply identity, markings and documentation before use. Qualified personnel must install and inspect the device, with the base fully seated and fixing appropriate to the structure. Check condition and markings before each use and observe the instruction inspection intervals and limits. Not for lifting people. This selection sheet does not replace the manufacturer instructions.
