CJP Series Single Acting Pin Cylinder (Short-Stroke Micro Cylinder)

Brand: SOLH by Richge Technology

Product Overview

     SOLH CJP series is single acting spring return pin cylinder. Core characteristics: ultra-short body, minimum installation footprint, unidirectional thrust and automatic spring reset upon air cut-off. Suitable for unidirectional precision push-pull movement under limited space, light load and high-frequency short-stroke stations. It is a classic model for miniature single-direction driving applications.

Core Structure & Design Features

     -- Drive Mode: Single acting (spring return). Extend when air supplied; automatically retract by spring without air pressure for safe operation.

     -- Bore Sizes: Ø4 / 6 / 10 / 16mm, cover micro to light payload range (0.1~3kg).

     -- Structure: Hard anodized brass body, stainless steel piston rod, no built-in cushion. Extra short outline, available for panel mounting or flush embedding inside equipment.

     -- Mount Types: Two core configurations — Panel mount (B) and Flush mount (S).

     -- Material & Sealing: Brass housing + NBR seals, oil-free operation, compatible with clean & slightly oily environments. Mechanical service life ≥3 million cycles.

     -- Sensor Option: CDJP variant with built-in magnetic ring, supports one magnetic switch for extended position detection.

Universal Core Technical Specifications (0.5MPa, Single Acting Spring Return)

Core Competitive Advantages

   1. Ultra-compact outline saves installation space

     -- Extra short body supports flush embedding inside machinery or panel mounting, cutting occupied space by up to 50% compared with standard cylinders, ideal for extremely confined stations.

   2. Unidirectional thrust with power-off reset

     -- Spring retraction activates once air supply cuts off. Safe for clamping, ejection and stop positioning unidirectional movements.

   3. Fast response & stable high-frequency operation

     -- Cushion-free low-friction sealing enables consistent cycling ≥250cpm for short-stroke repetitive tasks.

   4. Oil-free operation & extended service life

     -- Suitable for clean workshop conditions. Brass body and durable sealing guarantee ≥3 million maintenance-free cycles.

   5. Flexible mounting configuration

     -- Panel and flush embedded mounting available; rod end can be flat or rounded to match diverse mechanical designs.

Mounting Options & Typical Industrial Applications

   1. Mounting Forms

     -- Panel Mount (B): Flange fixed on equipment surface, convenient for external push & pull motion

     -- Flush Mount (S): Body embedded into equipment bore, only piston rod exposed for maximum space saving inside machinery

   2. Typical Application Scenarios

     -- 3C & Electronics: Micro part clamping, chip ejection, miniature jig drive, button durability testing

     -- Precision Instruments: Mini valve switching, fiber positioning, instrument fine adjustment, short-stroke stopping

     -- General Automation: High-frequency loading/unloading, label peeling, micro component transfer, unidirectional clamping

     -- Medical Equipment: Miniature instrument extension, micro fluid propulsion, precision positioning assemblies

3-Step Fast Selection Guide

   1. Bore selection based on payload

      -- Ø4 ≤0.3kg；Ø6=0.3~0.7kg；Ø10=0.7~2kg；Ø16=2~3kg. Reserve ≥50% safety margin.

   2.Stroke confirmation

     -- Standard stroke: 5/10/15mm. Shorter strokes deliver more stable high-frequency performance.

   3. Configuration matching

     -- Position feedback: Choose CDJP with built-in magnet plus one M9B switch to monitor extended position.

     -- Mount layout: Flush embedded mount (S) for internal equipment installation; panel mount (B) for surface assembly.
