SMC CD85N25-450C-B-X2018 C85 series Single-rod double-acting cylinder

Core Features

• ✓  Long-stroke drive: A 450mm stroke makes it suitable for automation scenarios requiring long-distance push-pull or large-range displacement.
• ✓  Air cushioning: Utilizes air cushioning, absorbing the piston's impact at the end of its stroke through an adjustable buffer valve, suitable for high-speed (up to 1500mm/s) heavy-duty applications.
• ✓  Standard compatibility: Complies with ISO 6432 standards, offering high interchangeability of mounting connectors and convenient maintenance and replacement.
• ✓  Magnetic switch compatibility: Built-in magnet (model name starting with D) allows for easy installation of magnetic switches for position detection; the steel strip mounting method facilitates fine-tuning.

Q: What equipment is a 450mm long-stroke cylinder suitable for?

A: It is ideal for scenarios requiring long-distance horizontal pushing/pulling or vertical lifting, such as:

Packaging machinery: Long-distance material or carton pushing.

Automated production lines: Transferring workpieces from one station to another.

Gate control systems: Automatically pushing and pulling heavy-duty doors or protective covers.

Positioning mechanisms: Achieving wide-range linear positioning.

Q: How is the high-speed performance of this cylinder? Are there any impact issues?

A: This cylinder has a maximum permissible speed of 1500 mm/s, classifying it as a high-speed cylinder. For long-stroke, high-speed applications, air cushioning is a crucial function—it absorbs the enormous energy of the piston reaching its end at high speed through an adjustable buffer valve, smoothly decelerating while effectively reducing noise and impact, protecting the cylinder itself and the equipment structure.

Q: What type of magnetic switch should be used with the CD85N25-450C-B-X2018?

A: The "D" in the cylinder model indicates a built-in magnet, allowing for the installation of a magnetic switch. According to the specification sheet, this model uses a "B" type magnetic switch (steel strip mounting). We recommend using SMC's D-M9 or A9 series magnetic switches (such as D-M9B), which, with the steel strip, can be directly fixed to the cylinder and their position is easily fine-tuned. When ordering, you can specify the magnetic switch model, such as CD85N25-450C-B-X2018-M9BL.
