F2 HYDRAULIC CYLINDERS

Characteristic Values

Usage : Mobile and light industrial hydraulics, plus offshore- and marine hydraulics, cylinder diameter from ø25 to ø300 mm both included.
Cylindertube : 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.
Pistonrod : Quality 20MnV6 corresponding to SS2142, Hard chrome 25ìm +/- 5ìm, Hardness min. 850 HV., Ra max. 0.2 ìm, external tolerance ISO f7
Alternative materials:
SS2387 corresponding to EN 1.4418 AISI 630 corresponding to EN 1.4542 AISI 329 corresponding to EN 1.4460 All qualities are delivered with hard chrome 25µm +/- 5µm, Hardness min. 850 HV., Ra max. 0.2 ìm, external tolerance ISO f7 Special material qualities can be delivered on request.
Seals : Piston seal: Polyurethane wiper ring with nitrile O-ring Rod seal: Lip seal of polyurethane. Wiper: Polyurethane with steel housing Guide 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 desirable Wiper 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.
