Custom Stainless Steel Hydraulic Cylinder
Toleng custom stainless steel hydraulic cylinders are engineered for the harshest corrosive environments — marine, offshore, food processing, pharmaceutical, and chemical applications.
Available in 304 and 316 stainless steel, these cylinders deliver exceptional corrosion resistance, hygiene, and durability where standard carbon steel cylinders fail.
304/316 Stainless Steel · Corrosion Resistant
What Is a Custom Stainless Steel Hydraulic Cylinder?
A stainless steel hydraulic cylinder is a linear actuator constructed from 304 or 316 stainless steel — offering superior corrosion resistance, hygiene, and durability in environments where standard carbon steel cylinders would rust, pit, or degrade.
With a custom stainless steel cylinder, you get a cylinder engineered to your exact specifications — custom bore sizes, stroke lengths, mounting configurations, stainless steel grades, seal materials, and port locations. These cylinders are ideal for food processing, pharmaceutical, marine, offshore, chemical, and water treatment applications where cleanliness and corrosion resistance are critical.
Why Choose Stainless Steel?
Stainless steel cylinders outperform carbon steel in corrosive environments
| Feature | Stainless Steel | Carbon Steel |
|---|---|---|
| Corrosion Resistance | ✅ Excellent — 304/316 stainless | ⚠️ Poor — requires coatings |
| Hygiene / Cleanability | ✅ Food grade, easy to sanitize | ❌ Not suitable |
| Service Life in Marine | ✅ 10+ years | 2–3 years |
| Initial Cost | 💰 Higher | Lower |
| Total Cost of Ownership | ✅ Lower — longer service life | Higher — frequent replacement |
| Best For | Marine, food, pharma, chemical | General industrial applications |
