DIRECT-ACTING TYPE

JRE Direct-Acting Hydro-Pneumatic Cylinder

Full-stroke high pressure in a compact form. The JRE operates like an air cylinder but delivers oil-intensified force from the very first millimeter — no pre-press phase, no separate boost stage. Ideal for short-stroke, high-force tasks: marking, bearing assembly, riveting, and sheet metal forming.

Why Direct-Acting?

Unlike pre-press types (JRA/JRAA) that use a two-stage cycle — fast air approach followed by oil-intensified boost — the JRE applies high pressure throughout the entire stroke. Total stroke equals power stroke. The result: cylinder-like simplicity with far greater force.

Pre-Press Type (JRA)
Approach Boost

Low-force air approach → high-force oil boost at the end. Two solenoid valves, 4-step cycle.

Direct-Acting (JRE)
Full-Stroke High Force

High force from start to finish. One solenoid valve, 3-step cycle. Short stroke, big output.

⚡

Full-Stroke High Pressure

Operates like an air cylinder but with oil-intensified force throughout the entire stroke — no low-force approach phase.

📈

Larger Output Than Air Cylinders

Delivers significantly more force than a same-bore air cylinder, with smooth and fast operating speed.

⏱

Simple 3-Step Cycle

Single solenoid valve (DT1) simultaneously controls air and oil cylinders. Return → boost → return — cycle complete.

📐

Short Stroke, High Force

Designed for applications needing high force over a short distance: marking, bearing assembly, riveting, forming.

Force vs. Displacement Profile

The JRE delivers high force across the entire stroke — there is no low-force approach phase. From the moment the piston begins moving to the end of stroke, oil-intensified pressure is fully engaged. This makes the JRE ideal for short-stroke applications where force must be present immediately.

FULL-STROKE HIGH FORCE Oil-intensified from first mm to end of stroke RETURN ~13,000 kgf 0 Stroke Position (mm) — Total Stroke = Power Stroke Output Force (kgf) 0 25% 50% 75% 100% Force from start Sustained high force
Full-stroke high force (oil-intensified)
Return stroke

Key difference from JRA: The JRA starts with a low-force air approach and only triggers oil boost at workpiece contact. The JRE engages full oil-intensified force from the very beginning — total stroke equals power stroke.

Pneumatic Circuit Diagram

The JRE uses a single solenoid valve (DT1) to simultaneously control the air cylinder and oil cylinder. Air flows through the treatment unit and solenoid valve, driving the air piston which directly actuates the oil piston for high-pressure output.

Operation Sequence (3-Step Cycle)

The JRE uses a simplified 3-step cycle — no independent boost stage control. DT1 simultaneously controls both the air cylinder and oil cylinder. This is simpler than the 4-step JRA cycle.

1

Return / Home Position

After connecting the pneumatic circuit per the diagram above, open the air source. The booster cylinder is in the return (home) position — DT1 is de-energized.

DT1 OFF
2

Direct Boost (Power Stroke)

DT1 energizes, switching the air circuit. Air pressure acts on the air cylinder piston, causing displacement. The oil cylinder simultaneously begins boosting — high force is applied from the start.

DT1 ON Air + Oil simultaneous
3

Return & Reset

After holding pressure as needed, DT1 de-energizes. The air circuit switches again, returning both the air cylinder and oil cylinder to their initial state simultaneously. One action cycle is complete.

DT1 OFF Hold time adjustable

Note: JRE is direct-acting type — the action cycle has 3 steps with no independent booster stage control. DT1 simultaneously controls the air cylinder and oil cylinder. Pressure-hold time is adjustable based on workpiece requirements.

Mounting Configurations

The JRE supports vertical (standard) and horizontal mounting. Horizontal mounting features a customizable front neck for side-press applications. Other mounting orientations can be specified before ordering.

Vertical Mount (Type A)

Rod-down installation on press frames, C-frames, and benchtop fixtures. The standard configuration for marking, riveting, and press-fit operations.

Standard — Type A

Horizontal Mount (Type B)

Rod-forward horizontal installation with customizable front neck. For inline pressing, slide mechanisms, and side-press fixtures where vertical space is limited.

Horizontal — Type B

Custom Mount

Rod-up, angled, or other special mounting orientations. Available as custom order with modified port and body configuration. Contact engineering for application review.

JRE vs JREB vs JRA: Which Cylinder?

JRE and JREB share the same direct-acting mechanism — only mounting direction differs. JRA adds a two-stage pre-press approach for longer strokes and higher tonnage. Compare all three to find the right fit for your application.

Selection Guide

When selecting a JRE model, consider these six key parameters. Our engineering team will help match the right configuration to your application.

1

Total Bore

Required booster cylinder bore diameter (mm) based on force and speed requirements.

2

Power Stroke

Required pressure stroke (mm). For JRE, total stroke equals power stroke — choose 5–25mm.

3

Output Tonnage

Required output force (tons) after boosting at the reference 6 kgf/cm² air pressure.

4

Operating Frequency

Required cycle frequency (cycles/min). JRE supports 25–45 cycles/min, inversely proportional to stroke length.

5

Return Force

Required return / lifting force (kgf) to retract the piston and tooling weight.

6

Mounting Type

Installation orientation: A (vertical, standard) or B (horizontal with customizable front neck).

Typical Applications

The JRE excels in short-stroke, high-force tasks where force must be present from the first millimeter. Ideal for marking, bearing assembly, electronic component riveting, and sheet metal forming.
