Features: compact outline, corrosion resistance, high-speed & high-frequency performance, oil-free operation. Widely deployed in food, pharmaceutical, electronics and general pneumatic automation equipment.

Core Structure & Design Features

   1. Standard: ISO 6432 (φ8–φ25), universal mounting dimensions for global mini cylinder market.

   2. Material: 304 stainless steel barrel, piston rod and lock nut; rust-proof, suitable for humid, weak acid and weak alkali working conditions.

   3. Structure: Roll-crimped end caps, tie-rod free, straight cylindrical shape, small size and lightweight.

   4. Operation Variants

     -- Single rod double acting (Standard)

     -- Single acting (spring return / spring extend)

     -- Double rod synchronous cylinder

     -- C85K Non-rotating rod type

   5. Cushion: Standard rubber cushion; air cushion (suffix C) optional for φ10–25 to reduce impact under high speed motion.

   6. Sealing: Special bidirectional seal with oil reservoir groove, low startup pressure, long service life under oil-free working condition.

   7. Position Detection: Built-in magnetic ring (code D) optional; magnetic switch installation modes: A=track groove, B=steel band groove.

Selection Comparison: C85 VS MI VS MA

   1. ✅ Preferred occasions for C85

     -- Food, pharmaceutical & electronics industry: Stainless steel, clean grade, anti-corrosion

     -- High speed & high frequency cycles: 50–1500mm/s short-stroke reciprocating

     -- Compact equipment layout: φ8–25 slim cylindrical body

     -- Humid & slightly corrosive workshop environment

     -- Global interchange demand: ISO6432 universal dimension for direct replacement

 3-Step Fast Selection Guide

   1. Bore selection: Calculate thrust & horizontal load, reserve ≥50% safety margin; choose smaller bore for higher frequency operation.

   2. Stroke confirmation: Add extra 10–20mm margin; maximum stroke 400mm.

   3. Configuration selection

     -- Built-in magnet: add code D

     -- High speed impact reduction: choose suffix C air cushion

     -- Anti-twist requirement: select K non-rotating version

     -- Match mounting form: N/F/L/M/G according to equipment structure
