VIILOCK Pneumatic Air Cylinder 32mm Bore 50mm Stroke
The VIILOCK TN32x50 cylinder is a compact double-acting unit with a 32mm bore and 50mm stroke. Best for small automation tasks where space is limited and a stable double-acting action is needed. The aluminum body offers light weight with adequate rigidity for repeated cycles. Suitable for applications requiring quick, precise extension and retraction with balanced force on both ends. A limitation is its smaller bore, which may limit the force available for heavier loads.
Best for: tight spaces in automation, light-duty clamping, and precise positioning tasks. Why selected: balances compact form with dependable double-action performance. Caution: not ideal for high-load or long-stroke requirements.
INTBUYING Air Cylinder Pneumatic Standard Cylinder
The INTBUYING SC 40 x 1000 is a long-stroke aluminum alloy cylinder with double acting action and a 40mm bore. It supports extended strokes for linear motion tasks, offering strong corrosion resistance and durability. Best for projects needing a longer reach and steady performance over many actuations. Its chrome-plated rod provides additional wear resistance. Limitation: larger size may require more mounting space and careful alignment.
Best for: long-reach linear motion and heavy-duty cycling. Why selected: robust construction with extended stroke for versatile applications. Caution: ensure mounting geometry accommodates its length.
BEILOCKERY Air Cylinder Pneumatic Cylinder
The BEILOCKERY model SC 80X1000 is a double-acting cylinder with an 80mm bore and 1000mm stroke. It’s designed for higher force demands and longer reach in standard industrial setups. The air pressure range supports varied operating environments, while the aluminum alloy body ensures durability. A potential drawback is the larger footprint, which may not fit compact equipment. Best for heavy-duty cycles requiring more push/pull force.
Best for: heavier automation tasks needing higher thrust. Why selected: larger bore increases force capacity while maintaining durability. Caution: confirm physical space before installation.
Heavy-Duty 3/4 Inch Roll-Up Door Cylinder Lock Set
This lock set from NiceGo combines a 3/4 inch roll-up door cylinder with three alloy keys. It emphasizes security and tamper resistance with a tubular mechanism and an integrated latch. Best for storage facilities or lockers needing quick, reliable locking. The design supports compatibility with common sliding bolt locks. Limitation: not a pure cylinder rod actuator for motion; intended for locking rather than linear actuation.
Best for: secure storage and locker applications. Why selected: strong tamper resistance and self-locking features. Caution: verify fit with your locking system.
Cladn100-250R-E Fine Lock Cylinder
The Cladn100-250R-E is a fine lock cylinder designed with double-acting capability and a single rod variant. It satisfies applications needing precise locking action with compact form. Best for smaller lock assemblies or devices requiring precise engagement. A limitation is that data on packaging is limited, so consider verifying packaging details before purchase.
Best for: compact locking applications with precise actuation. Why selected: small footprint and reliable locking mechanism. Caution: verify compatibility with your mounting hardware.
Buying Guide
What to consider when choosing a pneumatic cylinder rod lock
Identify the load and stroke needed. Longer strokes provide greater reach but require more mounting space.
Choose bore size based on force requirements. A larger bore yields more thrust; a smaller bore saves space and weight.
Decide between single vs double acting. Double-acting models offer bi-directional control; single acting can be simpler and cheaper for set-and-forget tasks.
Check material and corrosion resistance. Aluminum bodies are common and light; rust-resistant coatings extend life in harsh environments.
Assess compatibility with your system. Confirm mounting style, rod end options, and end-of-stroke cushions if needed.
Practical comparison questions
- Which cylinder fits my available space and mounting patterns?
- Do I need extended reach or higher force for my application?
- Is a heavy-duty lock cylinder necessary for security or just basic locking?
- Will the device operate in corrosive or temperature-extreme conditions?
Maintenance and installation tips
- Follow manufacturer guidelines for lubrication and seal replacement.
- Align mounting hardware precisely to prevent side loading.
- Inspect connecting rods and threads for wear after extended use.
Frequently asked questions
- What is a pneumatic cylinder rod lock used for?
- Which bore size should I choose?
- What is double-acting vs single-acting?
- Are aluminum bodies suitable for harsh environments?
- How important is stroke length?
- Can these cylinders work with standard storage lock systems?
It is used to control linear motion and locking mechanisms in automation and security applications, enabling precise actuation and hold positions.
Choose by required thrust. Larger bores provide more force; smaller bores save space and weight.
Double-acting cylinders use compressed air to extend and retract; single-acting rely on external forces or springs for retraction.
Yes, aluminum alloys provide light weight and corrosion resistance, but verify operating temperatures and sealing requirements for your environment.
Stroke length determines how far the piston moves; choose according to required reach and cycle length.
