Why do piston rods rust and how do I protect them?

Chrome-plated piston rods and bar products are normally specified to contain a minimum of 20 – 50 microns of hard chrome-plating. This hard chrome-plating is applied primarily for wear resistance, although it also has considerable corrosion resistance properties.

There are occasions when the rod surface can be exposed to a corrosive environment. This tends to occur when the cylinder is not being used, i.e., when new equipment is being stored prior to shipping from manufacturer or dealership.

In these instances it is best to provide some additional protection to the rod surface.
An inexpensive solution is to apply solvent-diluted oils such as:

• UNIL – SHX 12
• MOTUL – SAF PROTECT LD
• BP – STEMKOR 178

If these oils are not available, then prepare a mixture of 60% oil-based rust-inhibitor and 40% Kerosene.

 How do I apply protection to new piston rods?

1. Position the equipment as it will be stored and identify all of the remaining exposed areas of chromed rods.
2. Clean all dirt and dust from the exposed areas of the rods using a dry cloth.
3. Apply a thin coating of solvent-diluted oil mixture to the exposed areas of chrome. The mixture can be sprayed directly onto the chromed surface.
4. Inspect the chromed surface after 4 weeks and apply additional corrosion protection.

How do I apply protection to older piston rods?

1. Occasionally it might be necessary to store some equipment that has seen some service. The procedure described above can also be used for older equipment but more careful cleaning of the rod surface would be required.
2. Inspect the surface. Any damage to the rod surface will require extra attention.
3. Under no circumstances should sandpaper or other abrasive materials be used to clean the rod surface.
4. After the surface is clean it should be inspected again for damage to the chrome-plating. If damage is detected, more frequent applications of the solvent-diluted oil will be necessary to prevent corrosion during storage.
5. If the equipment is to be moved and then stored again for a period of time, these steps should be repeated for all shafts that were stroked during the move.

How do I prevent the piston rod’s hard chrome-plating from corroding?

To avoid damaging the hard chrome-plating make sure to keep the rod surface:

1. Clean – Avoid hitting or collecting gravel, stones etc… on the rod.
2. Dry – Water or humid air will start to corrode the chrome plate.
3. Regularly coated in quality corrosion preventative or slushing oil.

How long will it take for my order to be delivered?

Why do piston rods buckle (bend)?

Please refer to our cylinder calculator to measure the buckle ratio.
