Mounting types
Cylinder mounting types
The 6 most common mounting types are below. Visit the detail page for the full catalogue of the world's 52 mounting types, 16 of them with an ISO 6099 code.
TR
Trunnion (side-axis)
Twin trunnion pins from the side of the body; heavy axial load plus rotation. Excavator boom, concrete pump.
FL
Flange (flanged)
Bolted connection via front or rear flange; fixed body, no axis shift. Press, fixed industrial.
FT
Foot (foot-mounted)
Foot profile under the body, bolted from below; low profile, fixed cylinders.
RE
Rod End (rod-end joint)
Rotational joint added to the rod end: rod eye or rod clevis. Rotational freedom on both sides.
CR
Cross-tube (transverse tube)
A pin tube fitted transversely to the rod or body end; common in agriculture and light construction machinery.

Hydraulic cylinder selection and usage notes
Cylinder selection: bore, stroke, pressure calculation
Starting from the required force, speed and stroke in the application, selecting bore diameter + nominal pressure + mounting type.
Seal selection: NBR · FKM · PU · PTFE
Seal system based on operating temperature, fluid type (mineral oil, bio-oil, water-glycol), pressure and number of cycles.
Buckling length calculation (Euler)
Rod buckling risk at full stroke: verifying rod diameter and body-bearing distance with the Euler formula.
Telescopic cylinder: stage stopping
Internal stopping (built-in + buffer) and external stop ring selection; hydraulic shock management in long-stroke applications.
Test procedure: up to 1.5× nominal pressure
Individual pressure test of each cylinder before shipment; test duration, sealing acceptance criterion, test report.

Seal selection
Sealing material: pressure, temperature, application matrix
Seal kit selection depends on operating pressure, temperature range and fluid type. HPS provides an application-based selection recommendation.
NBR (Nitrile)
Pressure≤ 250 bar
Temperature≤ 90°C
General hydraulics, mineral oil · inexpensive, broad compatibility
HNBR
Pressure≤ 300 bar
Temperature≤ 120°C
Enhanced NBR: bio-oil + high temperature
Polyurethane (PU)
Pressure≥ 400 bar
Temperature≤ 100°C
Heavy-duty, abrasion resistance, high cycle life
FKM
PressureHigh
Temperature≤ 200°C
High temperature, chemical resistance, abrasive fluid
PTFE
PressureAny level
Temperature−50 / +250°C
Extreme temperature, chemical inertness, niche application
