Hydraulic cylinder rods
Durable Hydraulic Cylinder Rods
Hydraulic cylinder rods experience severe wear from cyclic loading and exposure to harsh environments. Stancor Bright Bars offers specially engineered steel bars to enhance durability and extend service life.
The wear problem
The primary wear mechanisms affecting hydraulic cylinder rods include sliding abrasion and impact wear. These factors can lead to surface degradation, pitting, and eventual failure of critical components, primarily at the rod's surface.
Recommended plate by component
| Component | Grade | Thickness | Why |
|---|---|---|---|
| Hydraulic Cylinder Rod | 080M40 / C45 | 25-50 | High hardness and strength provide excellent wear resistance. |
| Hydraulic Cylinder Rod | 709M40 / 42CrMo4 | 30-65 | This grade offers superior toughness for impact-heavy applications. |
| Hydraulic Cylinder Rod | 1.0715 | 20-40 | Optimized for high fatigue strength and resistance to abrasive wear. |
| Hydraulic Cylinder Rod | 1.4305 | 25-55 | Excellent corrosion resistance for harsh environments enhances service life. |
| Hydraulic Cylinder Rod | 1.7147 / 20MnCr5 | 20-50 | Case hardening properties ensure a tough core with a wear-resistant surface. |
Selecting the right plate
Choose the right grade
Select grades based on wear conditions and mechanical requirements.
Consider thickness range
Thickness impacts strength; choose accordingly for your application.
Evaluate environmental factors
Corrosion resistance may be critical in specific environments.
Assess impact loads
High impact loads require tougher grades for optimum performance.
Questions engineers ask
What is the best grade for hydraulic rods?
The best grade depends on specific application conditions, such as wear type and mechanical stresses. Generally, 709M40 / 42CrMo4 is recommended for high impact loads.
How does surface finish affect wear?
A smoother surface finish reduces friction and wear rates significantly, leading to a longer service life. Cold drawn and centreless ground finishes ensure optimal performance.
What thickness is best for durability?
Thicker bars tend to provide better resistance to bending and buckling under stress. However, balance is necessary to ensure the weight and cost align with operational requirements.
Can I use stainless steel for hydraulic rods?
Yes, stainless steels like UNS S30300 / 1.4305 are excellent in corrosive environments but need to be matched to mechanical load requirements. Consider the trade-off between corrosion resistance and strength.
