Side-Flexing: Optimal 881 M Series
 |
Magnetic System
Chains
881 M and 8857 M chains run in the Dual Magnetic System Curves. Magnetic System
chains are securely retained in the curve by the small permanent magnets, located under the
hinge of the chain in the upper part of the curve.
The 881 M series chains run in the same Dual Magnetic System curves as the 880 M and 879 M plastic chains.They have 42mm wide hinges, the same as 815 series, straight run chain, so use standard 815 series sprockets. The 8857 M chains, both stainless steel and plastic run in the new, heavy duty Dual Magnetic System curves.
The Novoflex 881 MO (Optimal Series Chain) is a further development of the 881 Magnetic System Chain. The standard radius for most 325 curves is 500mm. The 881 MO chain has a different shape which alters the minimum sideflex radius of the between the links. The smaller gap ensures greater product stability and less possibility for debris to become trapped between the links.
Series 8857
Stainless steel chains have a wider hinge, 57mm to match the hinge of the heavy duty LF 882 chains.
The wider hinge on the SSE 8857 M K 750 chain means a 35% increase in the tensile strength of this chain compared to the normal 42mm hinge wide chains. SSE 8857 M K 750, LF 8857 M K 750 and NG 8857 M K 750 chains have the same hinge width, and will run in the KMD 8857 Dual Magnetic System curves.
Wider sprockets are also available. These sprockets are manufactured from solid Polyamide and are also available in split form.
