Nominal pressure: 250 bar

Static proof pressure: 375 bar

Higher operating pressures on request.
The specified operating pressures are only valid for applications with shock-free operation. If extreme loads occur, e.g. as happens in high sequence cycles, the fixings and piston rod thread connections need to be designed for durability (fatigue strength).

Installation:Optional

Pressure fluid / pressure fluid temperature range:

  • HL, HLP, HFD-R: -20 °C to +80 °C
  • HFA: +5 °C to +55 °C
  • Water glycole HFC on request

Viscosity range: 2.8 to 380 mm2 /s

ISO cleanliness class
Maximum permissible degree of pressure fluid contamination is to ISO 4406 (c) class 20/18/15.

Stroke velocity:Up to 0.5 m/s (depending on the connection ports), higher stroke velocities on request.

Bleed screw as standard:Secured against unscrewing.

Undercoat:
The hydraulic cylinders are, as standard, painted with a max. thickness of 80 μm. Other color tones on request.

Acceptance:
Each cylinder is tested to Brant standards. Cylinders whose application data lies outside the stated values can be offered as a special version. Cylinders with piston Ø > 320 mm are available on request. For assembly, commissioning and maintenance cylinders, please contact us for more details.

Standards:

The installation dimensions of the cylinders and mounting styles meet the requirements of DIN 24333 and ISO 6022.

Clevis Mounted Cylinders

Cylinders with pivot mountings, which absorb forces on their centreline, should be used for applications where the machine member to be moved travels in a curved path. They may be used for tension (pull) or compression (push) applications. Fixed clevis mounting cylinders MP3 may be used if the curved path of the piston rod travel is in a single plane; for applications where the piston rod will travel in a path either side of the true plane of motion, the spherical bearing mounting MP5 is recommended.

Standards:

The installation dimensions of the cylinders and mounting styles meet the requirements of DIN 24333 and ISO 6022.

Trunnion Mounted Cylinders

These cylinders are designed to absorb force on their centre-lines. They are suitable for tension (pull) or compression (push) applications, and may be used where the machine member to be moved travels in a curved path, in a single plane. Trunnion pins are designed for shear loads only and should be subjected to minimum bending stresses.

Standards:

The installation dimensions of the cylinders and mounting styles meet the requirements of DIN 24333 and ISO 6022.

Foot Mounted Cylinders

MS2 cylinders do not absorb forces on their centreline. As a result, the application of force by the cylinder produces a turning moment which attempts to rotate the cylinder about its mounting bolts. It is important, therefore, that the cylinder should be firmly secured to the machine member on which it is mounted and that the load should be effectively guided, to avoid side loads being applied to the rod gland and piston bearings.
The MS2 foot mounted cylinder is not an ISO standard mounting.

Standards:

The installation dimensions of the cylinders and mounting styles meet the requirements of DIN 24333 and ISO 6022.

Head Mounted Cylinders

This mounting style is used for straight line force transfer applications in which the cylinder being pulled. The mounting flange surface should be flat, and the rod end should be piloted into it. The frame on which the cylinder is mounted must be sufficiently rigid to resist bending moments resulted from lateral force.
