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 and the ISO + NFPA + Parker code mapping.
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 · Viton · PU · ceramic
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: 1.5× nominal pressure
Individual pressure test of each cylinder before shipment; test duration, sealing acceptance criterion, certificate output.

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.
