Is this a chromed shaft for a hydraulic cylinder?

So in actual fact it's not for a hydraulic cylinder but a rotating shaft of a pump - a totally different animal. Not having seen the shaft in question it's hard to comment but I would be extremely surprised if it was chromed. A shaft like that is probably case-hardened in which case metal-spraying would be probably the suitable repair procedure.

Can cylinder rods be selectively plated?

If you have a chrome plating shop close handy that has the capability of doing hard chrome plating (as opposed to decorative) most cylinder rods can be selectively plated to repair small areas where the plating has been damaged.

Can a hydraulic cylinder be welded?

Welded hydraulic cylinders have no tie rods. Instead, the barrel is welded directly to the end caps and the ports are welded to the barrel. The front rod gland is generally bolted or threaded into the cylinder barrel, which allows the piston rod assembly and the rod seals to be removed for service.

What causes pitting on piston?

Pitting is little pin holes starting to develop in the piston . This can happen from too much compression , not enough shims or longer glow plug . Pitting is surface deformation on the piston head and underneath the button head.

Can hydraulic cylinders be repaired?

As a product group, cylinders are almost as common as pumps and motors combined. They are less complicated than other types of hydraulic components and are therefore relatively easy to repair. As a result, many hydraulic equipment owners carry out cylinder repairs themselves.

How much does it cost to have a hydraulic cylinder rebuild?

It can cost anywhere from $50 to a few thousand dollars to repair a hydraulic cylinder. The price varies with the size of the cylinder and the amount of repairs needed but we will always give you a fair deal.

Having made hydraulic rams in the past on my farm for a cat 60 conversion I would use induction hardened rod.The hard layer is about 0.10 thick and you need carbide to machine that.The center is not hard and can be drilled tapped or threaded with high speed tooling.Cutting to length can be with abrasive saw or parting off with carbide.I have welded the ends on using a 200 amp mig welder in the spray transfer mode and have not had any fail.The higher chrome thickness is what I would use.Some ag rams only use 0.5 thou but it tends to pit in a short time.Some rods are now made of black nitride material,but i think the hardend layer is not as thick and I do not no how it performs corrosion wise to 2 thou chrome..

IHCP - Induction Hardened Chrome Plated hydraulic cylinder rods

The polished surface is chrome plating. Chrome plating not only offers durable long-term protection against corrosion, but also provides a smooth finish that can be ground and polished to a precise diameter.

Cosmetic chrome commonly found on cars and motorcycles

Although Hard Chrome is more resistant to damage than Cosmetic Chrome, it cannot withstand impact on its own. If the base material is relatively soft, it will suffer damage with mild to moderate impact, and so will the chrome plating.

CPO - Chrome plated only - machined hydraulic cylinder rods

Obviously, CPO shafting is less expensive, as it does not require the added process of induction hardening. Standard off-the-shelf cylinders are mass produced using CPO shafting to keep costs as low as possible.

What is the problem with hydraulic cylinders?

The daily operations of a hydraulic cylinder require smooth operations from the piston rod as it extends outward and back again over and over. One of the minor problems that can turn into a big issue is rusting. Rust formation can lead to pitting and major operation problems.

Why do pistons rust?

Rust forms at a much faster pace when the equipment is outside. Daily weather or morning moisture can cause rust to form on the pistons. If you leave the pistons extended out from the housing, then the rod has exposure to the air and is more vulnerable to rusting.

Can piston rod pitting damage seals?

If you choose to operate the equipment, the piston rod pitting may damage the seals on the cylinder. Essentially, you could cause more damage and cause other fluids to leak outside of the equipment. Not only should you leave the equipment as it, but avoid any rust removal from the cylinders.

Can hydraulic cylinders be pitted?

If you purchase used hydraulic cylinders, pitting is one of the major problems you should look for in the product. Pitting can dramatically change the performance and operations of a hydraulic cylinder.

Can piston rods rust?

Not only will the piston rod s rust, but the open chamber of the cylinder may become vulnerable to rust. When the piston rods extend outward, air and moisture can leak inside the cylinder, creating issues. Rust buildup can result in jams or cylinders that do not operate smoothly.
