Alternative materials:
SS2387 corresponding to EN 1.4418AISI 630 corresponding to EN 1.4542AISI 329 corresponding to EN 1.4460All qualities are delivered with hard chrome 25m +/- 5m, Hardness min. 850 HV., Ra max. 0.2 m, external tolerance ISO f7 Special material qualities can be delivered on request.
Seals:Piston seal: Polyurethane wiper ring with nitrile O-ringRod seal: Lip seal of polyurethane.Wiper: Polyurethane with steel housingGuide rings: Composite material O-rings: Nitrile
Alternative materials:
Piston seal, rod seal and wiper:Wiper rings in PTFE with O-rings of nitrile. Recommended for intensive use plus applications, where low friction in the cylinder is desirableWiper rings in PTFE with O-rings of viton. Recommended for applications, where the seals can be exposed to temperatures above 80-100 C. Special seals can be delivered on request
Normal pressure:Max. 250 bar.
Test pressure:Max. 375 bar.
Piston speed:Max. piston speed 0,5 m/sec. If the piston speed in top or bottom exceeds 0,1 m/s, build-in damping in the cylinder is recommended.
Tubebreakprotection:Can be delivered built-in as special task.
Cussioning:Can be delivered built-in as special task.
Positioning:Can be delivered with different types of electronic positioning, e.g. from REGAL, MTS-Temposonics or BALLUFF.
Working temperat.:Working temperature 20 C to +80 C. Cylinders for working temperatures outside this area can be delivered on request.
Pressure medium:Mineral oil-based hydraulic oil.
Painting:Black primer. Can for extra charge be delivered e.g. shot blasted and painted in RAL 9005 corrosion class C3. Surface treatment according to other standards as e.g. ISO 12944-2 or NORSOK M-501 can be delivered on request.
