Tie rod vs. welded hyd clinders.

Hey folks.

I was out looking at wood splitters today.

I found some had tie rod type cylinders and some welded.

I was under the impression that the welded were better. Is this correct?

Are both rebuildable?

Thanks

Both are rebuildable.
Welded cylinders are generally a better choice but a tie rod cylinder is usually OK for light to medium hydraulic use. We do not use hydraulic tie rod cylinders where I work (steel mill). Under heavy loads the rods will stretch and leaks will develop. When under eccentric loading the tie rod cylinder will skew slightly at the caps and will leak. Most air cylinders are tie rod type.
 
For the most part welded cylinders are better. But if both can be rebuilt then it does not matter, especially for a home use log splitter.
 
From what I have seen, power steering cylinders that were welded they were not rebuildable.
 
You need to check what the pressure range of the cylinders is. We have some Deere implements around here that are tie rod type. Work good, easy to repair and the Deere system is 2000 PSI plus. You need to check the cylinder's manufacturing literature better.
 
I've had dozens of either type on farm machinery over the years and have noticed no discernible difference between the two types.

I don't know why log splitter service would be any different.

If anything, the tie rod types are easier to OH when the need arises, plus the barrel and ends are replaceable separately should there ever be some damage.
