Application Requirements

Performance Needs

When you pick a hydraulic cylinder, think about what your machine does. Each machine has its own job. Some machines lift heavy things. Others need to move fast or fit in small spaces. The hydraulic cylinder must fit these needs.

Here is a table to help you see what is important for performance:

Performance Criterion	What You Should Consider
Material Selection	Choose strong steel or stainless steel for the barrel and rod. Use special coatings for corrosion.
Surface Treatments	Pick hard chrome or HVOF coatings for extra wear resistance.
Seal System Optimisation	Use multi-stage seals made from materials like polyurethane or PTFE for tough jobs.
Geometric Design	Make sure the bore and rod sizes fit your force and stroke needs.
Cushioning Mechanisms	Add adjustable cushioning for smooth stops at high speeds.
Port Design and Placement	Place ports to keep fluid flowing well and avoid turbulence.
Mounting Configuration	Match the mount to the load direction and movement.
Corrosion and Contamination	Use paint and coatings to protect against rust and dirt.

You should always use a safety factor. For hard jobs, use 1.5 to 2 times the load. Think about stroke length, speed, and the hydraulic fluid type. Some cylinders must handle high pressure or very hot or cold places. Custom hydraulic cylinders can be made for long strokes, fast speeds, or special mounts. You might want sensors or valves for better control and safety.

Environmental Factors

Hydraulic cylinders face many problems in tough places. Temperature, water, and chemicals can cause damage. Here are some things to watch for:

• Extreme cold makes seals hard and thickens hydraulic fluid. This slows machines and can cause leaks.

• High heat can break seals and fluid. It causes more wear and can make the cylinder fail.

• Humidity and condensation cause rust inside the cylinder. This can block valves and break parts.

• Corrosive chemicals like acids or saltwater damage seals and metal. This happens a lot in mining or marine work.

• Dust and dirt scratch surfaces and wear out seals. This is a big problem in mining and building sites.

To keep your hydraulic cylinder working, use special seal materials and coatings that stop rust. Stainless steel and good surface treatments help stop rust and wear. Always use the right hydraulic fluid for your place. Good design and regular checks help your cylinder last longer, even in the hardest places.

Material Selection

Corrosion Resistance

When you choose a hydraulic cylinder for a tough job, you want it to last. Corrosion can ruin a cylinder fast, especially if you work near the sea, in mines, or with food. You need to pick the right materials. Stainless steel is a top choice. It fights rust and keeps your hydraulic system working longer.

Let’s look at some common materials and how they compare:

Material	Properties	Pros	Cons
Stainless Steel 304	Corrosion resistant, durable in acidic env.	Widely available, environmentally friendly	More expensive, harder to machine
Stainless Steel 316	Extra corrosion resistance, strong	Great for food and marine use	Higher cost than 304
2507 Super Duplex	Top corrosion resistance, very strong	Best for seawater, mining, harsh chemicals	Expensive, harder to work with
Carbon Steel	Strong, cost-effective	Cheap, easy to machine	Needs coating to stop rust

You often see 316 stainless steel in food factories and on ships. It handles salt and cleaning chemicals well. 2507 super duplex stainless steel is even better. It stands up to seawater and strong chemicals in mining. You get more strength and better cylinder longevity with 2507, especially where rust is a big problem.

Tip: If you work near the sea or with chemicals, ask for 2507 or 316 stainless steel in your hydraulic cylinder.

Special Environments

Not every place is the same. Some jobs need more than just rust protection. You might work in freezing cold, high heat, or with strong acids. You need a hydraulic cylinder that matches your environment.

Here are some things to think about:

• 2507 stainless steel works well in seawater, oil rigs, and mining. It is strong and does not rust easily.

• 316 stainless steel is good for food, drink, and clean rooms. It is safe and easy to clean.

• You need the right seals and coatings for each job. Good seals keep dirt and water out. Special coatings like hard chrome or ceramic help the rod last longer.

Choose the Right Mounting Option

Mounting Types

Picking the right mounting helps your equipment stay safe. It also makes it last longer. BOS Hydraulics has many mounting options for hydraulic cylinders. Each mounting type is good for different jobs. You need to know which one is best for your work.

Here’s a table to help you compare the main mounting types and how they affect how you fit them and how steady they are:

Mounting Type	Description & Application	Effect on Installation & Operational Stability
Flange mounts	Strong, rigid mounts for stationary cylinders.	Provide sturdy connection; ideal for fixed setups; need correct alignment to avoid failure.
Clevis mounts	Pivot mounts for angular movement, common in mobile equipment.	Allow pivoting in one plane; good for short strokes; can suffer from side loading if not aligned.
Trunnion mounts	Pivot mounts at head, cap, or middle; can use bearings.	Offer better strength and stability than clevis; handle dynamic loads; help with correct alignment.
Lug mounts	Fixed mounts with tabs welded or formed on cylinder ends.	Give rigid attachment; not tolerant of misalignment; side lug mounts need extra support for heavy loads.
Foot mounts	Flat base bolted to a surface, supports cylinder lengthwise.	Reduce bending stress; easy to install; need correct alignment to prevent wear.
Side mounts	Mounted on cylinder sides, not through centreline.	Easy to fit and maintain; can cause side loads and wear if not designed well.
Pivot mounts	Includes clevis and trunnion; allow swinging motion for loads moving on an arc.	Absorb forces along centreline; good for dynamic machines; not ideal for long strokes without special design.

Tip: Always check the alignment when you install a cylinder. This helps it last longer and work better.

Installation Needs

You must match the mounting to your machine and its job. Flange mounts are good for heavy machines that do not move. Clevis and trunnion mounts are better for machines that need to turn or move. Lug mounts are strong but need careful alignment. If you pick the wrong mounting, you might see bending, leaks, or parts wearing out too soon.

Custom hydraulic cylinders let you choose the best mounting for your needs. BOS Hydraulics can add special things, like valves or sensors, to the mounting. This makes your system safer and easier to look after. Always think about the space you have, the forces on the cylinder, and how often you need to check it.
