CDJ2 Series Stainless Steel Mini Cylinder ( Double / Single Acting)

Brand: SOLH by Richge Technology 

Product Overview

     SOLH CDJ2 series is magnetic-ring equipped pen-type stainless steel mini cylinder, fully interchangeable with SMC CJ2 series. Bore sizes: φ6 / 10 / 16mm. Outstanding features: ultra-compact outline, lightweight construction, corrosion resistance and stable high-speed high-frequency operation. Widely used in electronics, medical, food processing and precision automation confined-space stations; mainstream miniature linear actuator.

Core Structure & Design Features

   1. Standard Specification: Matches SMC mini cylinder dimensional standard (non ISO standard), universal mounting dimensions in industry.

   2. Material: 304 stainless steel barrel & piston rod, rust-proof and corrosion resistant, suitable for humid, weak acid, weak alkali and clean production environments.

   3. Structure: Straight round barrel, crimped end caps, tie-rod free design, ultra-small volume. CDJ2-16×100 only approx. 120g.

   4. Operation Variants

      -- CDJ2B Double Acting: Air supply on both ends, universal standard model

      -- CDJ2E Single Acting: Spring return; CDJ2ET: Spring extend

     -- CDJ2KB Non-rotating: Hexagonal piston rod for anti-twist and precise positioning

   5. Cushion: Standard rubber cushion; air cushion (suffix Z) optional for high-speed applications to reduce impact and noise.

   6. Sealing: Low-friction seal with oil reservoir groove. Low starting pressure (0.06MPa), oil-free operation, service life ≥5 million cycles.

   7. Position Detection: Built-in magnetic ring, compatible with M9B / A93 / Z73 series magnetic switches for piston position monitoring.

   2. Main Derivative Series

     -- CDJ2B: Standard double acting

     -- CDJ2E: Single acting, spring retract (auto retract after air cut)

     -- CDJ2ET: Single acting, spring extend (auto extend after air cut)

     -- CDJ2KB: Non-rotating hexagonal piston rod

     -- CDJ2RB: Direct mount slim version without mounting bosses

3-Step Fast Selection Guide

   1. Bore selection: Calculate required thrust/load, reserve ≥50% safety margin; choose smaller bore for higher cyclic speed.

   2. Stroke confirmation: Add extra 10~20mm margin on effective travel; Max stroke: double acting 200mm, single acting 100mm.

   3. Configuration matching

     -- Action type: Double acting → B; single acting spring retract → E; anti-twist positioning → KB

     -- Cushion: High-speed operation select Z air cushion

     -- Position feedback: Select magnet equipped model, match M9B/A93 magnetic switches
