Due to the friction between fixed manifold and rotating central body, the indexing table must provide a higher rotation torque than the one shown in the schedule below! Standard equipment Chuck unit 1 set of soft blank top jaws (PBI-C excluded) 1 set T-nuts with bolts (PBI-C excluded) Ordering example 3-jaw chuck PBI-C/D 250 or 2-jaw chuck PBIL-D2 165 INCH SERRATION 2 or 3 jaws TONGUE & GROOVE 3 jaws Pneumatic chuck for indexing tables Ø 165 - 315 mm ■ Built-in cylinder ■ 2 and 3 jaws BIS Specials Website: www.bisspecials.com Email: info@bisspecials.com Tel: (0031) 0313 482566 Website: www.bisspecials.com Email: info@bisspecials.com Tel: (0031) 0313 482566
