SKF Chaîne d'extension TKSA 51-EXTCH

2 × Extension chains of 1 m (3.3 ft.) for shaft diameters up to 450 mm (17.7 in.) Extension chains can be connected to the supplied mounting chains to increase their length. Longer chains enable alignments with larger shaft or coupling diameters. If one set of extension chains is not enough, two sets can be combined or a magnetic V-bracket can be used.
