Compact dimensions allow high performance features such as, high speeds, good accuracy and repeatability. They can easily be combined to multi-axis systems. Excellent price-/performance ratio and quick delivery time are ensured. The compact, precision-extruded aluminum Profile from AL 6063, with two parallel, integrated, Zero- backlash rail guide systems, allows high load capacities and optimal cycles for the movement of larger masses at high speed. In the Linear Units CTV a precision ball screw, with tolerance class ISO7 ( ISO5 on request), with reduced backlash of the ball nut is used. Two parallel circulating antistatic polyurethane sealing strips and an aluminum cover are ensuring to protect all the parts in the profile from dust and other contaminantions. Different carriage lengths with lubrication port allows for easy re-lubrication of the ball screw and Ball rail guide system and allows the possibility to attach additional accessories. The re-lubrication can also be done through maintenance holes on the side of the Profile. The aluminum profile includes T-slots for fixing the Linear Unit and for attaching sensors and switches. Also, a Reed switch can be used here. For the linear units CTV various adaptation options, for attaching (or redirecting), for Motors or Gearboxes are available. The aluminium profiles are manufactured according to the medium EN 12020-2 standard Straightness = 0,35 mm/m; Max. torsion = 0,35 mm/m; Angular torsion = 0,2 mm/40 mm; Parallelism = 0,2 mm 70 18 126 3 260 75 j6 180 h6 L MOTOR SPECIIFC C3 115 M20 x 2.5 x 42 20 x 12 x 90 h9 KEY 235 4x M16 x 2.0 x 28 210 BCD 9 0 ° D E F C 1 2 3 4 B A 3 2 1 5 C D 4 6 7 8 A B AER235-1 WEIGHT: A3 SHEET 1 OF 1 SCALE:1:5 DWG NO.
