ALUMINUM TUBES FOR PNEUMATIC CYLINDERS: SQUARE SERIES 99 ISO 15552 ex ISO 6431
Aluminum tubes suitable for the production of pneumatic cylinders for drives. These tubes are extruded, in aluminum alloy EN-AW6063T6 subsequently calibrated - broached by mechanical processing and finally anodized class 20 µm
NOTE: SPECIAL TECHNICAL CHARACTERISTICS HIGH QUALITY PRODUCT after an
accurate 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
Anodization:
- oxide layer thickness: class 20 µm +10/-4 (internal) +10/-8 (external)
- oxide layer hardness: 420 HV25 +130/-30
Roughness of internal diameter:
Roughness of internal diameter: -Ra radial ≤ 0.6 µm -Rmax radial ≤ 9 µm -Ra
axial ≤ 0.4 µm
Full range of our aluminium profiles available on the website: www.omar-alluminio.it
Detail of the slots for fixing accessories:
From ø32 to ø100: fixing holes are prepared for metric
threading by rolling or for the use of self-tapping screws
ø125: fixing holes are prepared for metric threading by
traditional chip-removal tapping
