"For gripping workpieces internally, Kitagawa's KEM Series of Expanding Mandrels is the best option. Able to grip internal diameters from 12.4mm to 82.7mm as standard, the KEM series' ID clamping offers full OD part access. With parallel expansion for optimum accuracy and grip force, the exanding sleeves are fully sealed for complete protection. The pull-back design draws workpiece securely against a part locator for 'dual-contact' rigidity and all mandrel models have a common flange configuration, enabling full interchangeability with all back bodies.Customized systems available - up to 635mm possible. 1\/2-length, extended length and dual sleeves - for supporting a wide range of parts."
