SMC CD85N25-80-B Pneumatic Air Cylinder (New Original)
1. Product Overview
The CD85N25-80-B is a standard ISO 6432 certified single-rod double-acting pneumatic cylinder belonging to SMC CD85 series. It is newly original genuine industrial linear pneumatic actuator with built-in permanent magnet inside the piston, basic clevis integrated mounting structure, rubber bumper end cushioning, 25mm bore diameter and 80mm standard stroke lengthsmc-static….
Complying with international ISO 6432 and CETOP RP52P unified dimensional standards, this cylinder is universally interchangeable with all brands’ same-spec ISO miniature cylinders. It converts compressed air pressure into reciprocating linear mechanical motion, widely deployed in electronic assembly equipment, automated fixture jigs, packaging machinery, textile production lines, small automation sorting devices and precision pick-and-place stations. The built-in piston magnet supports installation of SMC magnetic auto switches to detect piston extension/retraction positions for automatic cycle control of pneumatic circuits.
2. Main Functions
- Bidirectional linear reciprocating movement driven by compressed air: piston extends and retracts under air pressure alternately (double-acting operation mode).
- Built-in piston permanent magnet cooperates with magnetic switches to feedback stroke position signals for automated logic control.
- Rubber bumper cushioning absorbs piston impact force at both end positions, reducing vibration, noise and internal component wear.
- Standard external metric thread on piston rod end allows quick assembly of rod end joints, connecting brackets and workpiece fixtures.
- Multi-style optional mounting adapters support horizontal, vertical and pivot installation to fit diverse equipment layout demands.
- Non-lube operation design: can work normally without continuous oil mist lubrication of compressed air pipeline.
- Excellent dust-proof sealing structure adapts to ordinary dusty workshop production environments steadily for long-term cyclic operation.
