* Can be loaded axially. Radial loading is possible, without chip guard. ** 240 bar in the cylinder created by the pressure booster (ratio 1:4 RX2 + RX3). 375 / 485 / 450 bar in the cylinder created by the pressure booster (ratio 1:7.5 RX4-6.1). In case a lower pressure for the function „Steady Rest close“ is needed, two independent pressure regulators for open and close have to be installed. *** The RX 2 has no coolant flush. Dimension Z is w/o the 3 pcd. Chip guard.
