Festo DSBG Standard Cylinder — ISO 15552 Profile Cylinder with Tie Rod (238 Models) Complete Specs & Selection Guide

Festo DSBG Series Standard Cylinder is a profile cylinder based on ISO 15552 (ISO 6431 / VDMA 24562), whose defining feature is the integrated tie rod construction — tie rods built into the profile barrel, combining the lightweight advantage of profile cylinders with the robustness of tie rod cylinders. The DSBG comes standard with self-adjusting pneumatic end-position cushioning (PPSA) that automatically adapts to load and speed changes without manual adjustment. Adjustable cushioning (PPVA) and elastic cushioning (P) versions are also available for diverse application requirements. The DSBG series covers bore 32 mm to 320 mm, maximum stroke 500 mm, with 238 standard part numbers.

As the “tie-rod-reinforced” member of the Festo profile cylinder family, the DSBG is especially well suited for automation applications with medium loads, frequent direction changes, and mild vibration, and is widely used in packaging machinery, material handling, assembly lines and woodworking machinery.

Key Product Highlights

• ISO 15552 International Standard: Fully compliant with ISO 15552 (VDMA 24562); mounting dimensions 100% interchangeable with equivalent products
• Integrated Tie Rod Construction: Tie rods built into the profile barrel; higher torsional strength than conventional profile cylinders, reliability approaching that of tie rod cylinders
• PPSA Self-adjusting Cushioning Standard: The vast majority of part numbers include PPSA self-adjusting pneumatic end-position cushioning as standard, automatically adapting to load changes with no manual adjustment needed
• Three Cushioning Options: PPSA (self-adjusting), PPVA (adjustable), P (elastic/rubber cushion) — covering the full range from precision to standard applications
• Wide Bore Range: 11 bore sizes from 32 mm to 320 mm, covering the complete range from small to heavy-duty
• Profile Barrel: Aluminium alloy profile barrel — lightweight, high rigidity, with integrated sensor mounting grooves on the barrel surface
• Wide Stroke Selection: Standard strokes from 25 mm to 500 mm, covering the vast majority of positioning and push-pull applications
• Double-acting: Compressed air acts in both directions; equal thrust on advance and retract strokes

Part Number Structure

DSBG part numbers follow this structure:

DSBG-{Bore}-{Stroke}-{Cushioning}-{Option}

Example: DSBG-63-100-PPSA-N3

• DSBG: Series designation (profile cylinder + tie rod structure)
• 63: Bore 63 mm
• 100: Stroke 100 mm
• PPSA: Self-adjusting pneumatic end-position cushioning
• N3: Standard option package

Cushioning types:

• PPSA: Self-adjusting pneumatic end-position cushioning — automatically detects load and speed, no manual adjustment required; recommended for most applications
• PPVA: Adjustable pneumatic end-position cushioning — manually adjust cushioning intensity; suitable for applications with large load variation
• P: Elastic cushioning/cushion ring — no pneumatic cushioning; absorbs impact via elastic washer; available only for large bore (≥160 mm)

FAQ

Q1: What is the difference between the DSBG and DSBC, and how do I choose?

A: The DSBG integrates tie rods inside the profile barrel, giving it higher torsional stiffness and reliability — especially suited for applications with lateral loading or vibration. The DSBC is a pure profile structure, lighter and more cost-effective. Choose DSBG if your application involves significant vibration or demands the highest reliability; DSBC is sufficient for general standard applications.

Q2: Does PPSA self-adjusting cushioning really require no manual adjustment?

A: Yes. PPSA (self-adjusting pneumatic end-position cushioning) uses an internal mechanism to automatically detect piston speed and load, adjusting cushioning force in real time. No manual adjustment is needed after installation — even when the load varies within a certain range, it adapts automatically. This significantly reduces commissioning time and maintenance costs.

Q3: Why can the DSBG achieve a maximum bore of 320 mm?

A: The integrated tie rod construction gives the DSBG greater structural strength, allowing it to support much larger bores than the DSBC (maximum 100 mm). DSBG cylinders with bore 160 mm and above typically come standard with elastic cushioning (P), suitable for heavy-duty push-pull applications such as large valve actuation and heavy material handling.

Q4: Can the DSBG replace an equivalent tie rod cylinder?

A: In most cases, yes. The DSBG combines the lightweight advantage of profile cylinders with the strength of tie rod cylinders, and fully conforms to ISO 15552 mounting dimensions. If your existing equipment uses a standard ISO 15552 tie rod cylinder, the DSBG can replace it directly while also benefiting from the easier sensor installation of a profile cylinder design.
