Round Body Cylinders Overcome Harsh Conditions and Limited Space

Designers whose machines call for actuators typically have two constant demands: integrate cylinders into smaller spaces and work with a tighter budget. Machines intended for use in harsh or washdown-intensive environments are no exception, and they have the added factor of requiring a robust air cylinder to stand up to the tough conditions. Round body cylinders can check off all these boxes and offer versatility for use in a wide variety of applications.

The Basics of Round Body Cylinders

Round body cylinders are typically used for moving, holding, lifting and pushing low or medium loads in applications with limited installation space. They are also appropriate for applications where minimal lateral forces act on the rod. Round body cylinders are characterized by their light weight and small widths. They’re also desirable for applications with a tight budget thanks to their economic, non-repairable design and easy replacement. In fact, many round body cylinders are directly interchangeable and dimensionally compatible across other popular, compliant brands.

And when it comes to harsh environments and food production applications, round body cylinders offer exceptional durability. Though most are constructed with aluminum heads and caps, many manufacturers offer variants with anodized end caps or are made with Delrin® or other polymer materials that are lightweight, cost-effective and typically resilient to chemicals. Stainless steel is a more robust option, and it is well-suited for acidic applications. Fabco offers two round body cylinder families that are robust and effective options for harsh environments and food production applications:

Fabco Round Body Lines: F Series and H Series

Fabco’s round body cylinders come with a 304 stainless steel body and feature a 303 stainless steel ground, polished and roller-burnished cylinder rod and high-strength aluminum piston, making them appropriate for light-duty applications in food and beverage or packaging equipment.

F Series: These cylinders are designed to be directly interchangeable with the leading competitors in the industry. They feature quick response and full flow port performance, pre-lubrication for maintenance-free operation and a rod bushing made with oil-impregnated sintered bronze for wear resistance and long life. Bore sizes range from 5⁄16 through 3 inches with stroke lengths up to 60 inches, standard. Standard variants constructed from either Delrin or stainless steel are also available.

H Series: This non-repairable actuator is interchangeable with the previous version offered by Humphrey, and interchanges as well as those from a wide range of competitor units. The H Series’ unrestricted porting design results in maximum air flow, fast response and smooth rod movement. Bore sizes range from ½ to 2 ½ inches, and standard stroke lengths go up to 60 inches. The H Series includes options for anodized heads and caps for a cost-effective washdown solution.

Round Body Cylinders Offer Peace of Mind

Machines used in harsh environments or food zones are not exempt from space and budget constraints. Round body cylinders such as the interchangeable F Series and Humphrey Interchange H Series are designed to overcome both space limitations and challenging environments. Their combination of performance, reliability and customization options will give you peace of mind over a long operating lifetime.

Air Preparation Products Keep Pneumatic Systems at Peak Performance

When designing and building a pneumatic system for your industrial applications, keep in mind that even the most durable, highest-performance components will suffer from sub-optimal performance and damage that will reduce their expected life if the compressed air is of poor quality. Compressed air entering the system contains particles that can, for instance, damage seals in valves and cylinders. Water can also compromise systems by washing away lubricants. And, the compressed air must be at the right pressure. Any of these conditions can cause critical equipment to fail prematurely.

If you want to get the best performance and longest life out of the equipment throughout your pneumatic system, air preparation is a must. Various individual components and combination units can help you ensure proper air quality. For example, filter-regulator-lubricator (FRL) units are among the most common components, and their modularity allows designers to create the right combination for the system. Here’s an overview of some of the air preparation products that can keep pneumatic systems clean and functioning, using Fabco-Air products as examples:

  • Filters. Filters can remove particles before they can contaminate and compromise components around your system. Certain models remove materials down to 5µ, making them an effective first line of defense.
  • Regulators. Make sure your clean air is at the right pressure throughout your system. Fabco’s FA user-adjustable regulators feature a square embedded pressure gauge with psi scale and one MBCR-type mounting bracket and panel nut.
  • Lubricators. These units inject a small amount of oil into your system to keep downstream components running smoothly by reducing wear and preventing corrosion.
  • FRLs. Filter-regulator-lubricator units offer comprehensive air management while making efficient use of space.
  • Combinations. Air preparation products can be combined into two-in-one and three-in-one units to suit your space and budget requirements.
  • Custom/Special. If standard or combination air preparation products don’t match your system’s needs, Fabco can create custom units as specials. In fact, we specialize in modified products.

Filters, regulators and lubricators are available with a wide range of NPT port sizes and operate at up to 145 psi of pressure. In addition, Fabco’s lineup of preparation products also features mist separators and micro-mist separators that remove particles as small as 0.01 µ, plus a full range of valves to keep personnel safe including lockout-tagout, soft-start and quick exhaust valves.

Ensure System Reliability and Safety

Air quality is critical for your pneumatic system’s productivity and reliability. In order to get the most from your pneumatic systems and ensure long operating lifetimes for components, you must maintain the right air pressure and protect against contamination and moisture. Fabco-Air offers a broad lineup of air preparation products that will keep your pneumatic systems running smoothly and safely.
