Extruded section, aluminium EN AW6060. Version Hard anodised aluminium, 50 µm. Hardness 500 HV. Note The aluminium guide rail has good thermal conductivity and importantly heats only at continuously very high speeds. ** lengths L2 = 20 mm * and L = 500 mm included L2 and L only available in full mm.

Bearing block and carriage aluminium alloy, anodised. Guide columns stainless steel, ground. Spindle stainless steel, rolled thread. Guide bearing maintenancefree. Position indicator plastic. Version Radial play on guide < 0.02 mm. No axial backlash. Spindle selflocking, with additional lock. Note Due to the practically playfree guides and absolutely playfree spindle, loosening or clamping of the spindle is not required during adjustments. Digital position indicators with 0.1 mm display accuracy, digits increase with right rotation. The display value of the position indicator can be adjusted by turning the carrier ring. The mounted position of the position indicator can be set in 4 positions with a screw. Within the respective sizes, the positioning stages can be easily combined using the modular principle.

Sliding carriage Base structure in extruded section, aluminium EN AW6060. Sliding elements Maintenance free plain bearing iglidur® J. Version Eloxalcoated E6/EV1. Black thermoplastic Note With a low rate of inerita, high accelerations and short term extreme speeds up to 30 m/s are possible. DryLin® T linear glide guides are resistant to dirt and corrosion and are adjustable, maintenancefree and quiet. Application temperature max. 80 °C. As no lubricants are used they are recommended for use in food, medical, and clean room technologies. Manual clamping was developed for simple functions. Polymer under constant pressure has a tendency to creep which causes a decrease in clamping force over time (up to 70%), which means that no safetyrelevant parts should be clamped. Suitable guide rails see 21200. Drawing reference 1) manual clamping

Base and rotary table aluminium alloy. Hollow shaft stainless steel. Preloaded worm gear steel. Claw coupling aluminium with polyurethane coupling spider. Version Aluminium alloy anodised. Note for ordering The unit is supplied with the position of cable outlet or control unit as shown in the drawing. Note Rotary positioning stages for motorised adjustment and positioning tasks. The preloaded worm gear runs virtually playfree. The bearing of the worm shaft offers maximum radial rotational accuracy. Cables can be routed through the large bore in the hollow shaft. The adjustable positioning ring is used to determine the rotational reference point to the position of the assembled part. Proximity switches can be mounted with the optionally available sensor holder (21094). The suitable programming software and interface cable for the stepper motor with positioning control are available as accessories (2500015).
