ALUMINUM TUBES FOR PNEUMATIC CYLINDERS: 89 SERIES with slotted holes for tie rods
Aluminum tubes suitable for making pneumatic cylinders for drives. These tubes are extruded, in EN-AW6060T6 / EN-AW6063T6 aluminum alloy, subsequently calibrated - broached by mechanical machining and finally anodized class 20 µm
NOTE: SPECIFIC TECHNICAL CHARACTERISTICS HIGH QUALITY PRODUCT After careful extrusion the profile is subjected to a special cold calibration process of the jacket (internal part)
Minimum mechanical characteristics:
Rm= Mpa 245 Rp0,2= Mpa 200 A5%=8 HBW=80
Anodizing:
- thickness of the oxide layer: class 20 µm +10/-4 (internal) +10/-8 (external)
- hardness of the oxide layer: 420 HV25 +130/-30
Internal diameter roughness:
Internal diameter roughness: -Ra radial ≤ 0,6 µm -Rmax radial ≤ 9 µm -Ra axial ≤ 0,4 µm
Complete range of our aluminum profiles available on the website: www.omar-alluminio.it
The fixing holes are prepared for the insertion of steel tie rods.
