Hydraulic Cylinder Types Industrial, Agricultural, Specials, and NFPA
Hydraulic cylinders are the backbone of motion and force in heavy machinery. This article compares the main commercial types — industrial welded, agricultural, specials/custom, and NFPA (interchangeable) cylinders — explains their differences, where they sit in the marketplace, and what to expect on cost and selection.
Agricultural Cylinders
- Typical applications: loaders, bale handlers, tilt systems on implements, materials handling equipment of many sorts.
- Strengths: rugged for field conditions, corrosion protections, simplified maintenance.
- Market position: sold through agricultural parts channels and implement OEMs; valued for uptime and serviceability.
- These are mass produced, and built to standard dimensions, so are readily interchangeable from one manufactures product to another.
- The quality of materials used in manufacturing varies greatly from one manufacture to another. We use and recommend Australian made Cross Hydraulic cylinders. (May use links to cylinder section)
- Cost: generally low to moderately priced, and readily available.
Industrial Welded Cylinders
Industrial welded cylinders are built for continuous, heavy-duty service on factory equipment, material handlers, and construction gear. They use a welded barrel and threaded or welded end caps for robustness and typically feature hardened, honed bores and heavy seals for long life. These are widely available in Australia from manufacturers such as Statewide Hydraulics.
- Typical applications: presses, lifts, compactors, excavator attachments.
- Strengths: compact envelope, high pressure ratings, easy to customise, good shock tolerance.
- Market position: commonly used in earthmoving and other mobile machinery. They are usually specifically designed for specific applications.
- Cost: medium to high depending on bore, stroke and materials; economical in volume but more expensive than simple tie-rod units for heavy duty specs.

Specials and Custom Cylinders
Specials cover any cylinder with non-standard materials, geometries, sensors, high-temperature seals, ceramic rods, integrated valves, or unusual mounting arrangements. Shops and specialist manufacturers produce bespoke units to meet performance or space constraints.
- Typical applications: mining gear, marine winches, furnace actuators, custom automation.
- Strengths: engineered to exact duty cycles, integrated sensors (LVDT/encoders), exotic metallurgy.
- Market position: lower-volume, higher-margin segment sold directly to OEMs and end users who need problem-specific solutions.
- Cost: high; bespoke design, testing and certification drive price.
- As there is an infinite amount of possible combinations in this product range we recommend contacting Statewide Hydraulics directly to discuss your application. ????

NFPA Interchangeable Cylinders
- Typical applications: factory automation, presses, general industrial service.
- Strengths: easy replacement, broad aftermarket availability, predictable sizing.
- Market position: favored by Industrial and heavy-duty operations.
- Manufactured to standard designs and performance specifications, and generally interchangeable form one manufacturer to another.
- Cost: usually competitive; standardization reduces design and stocking costs.
