The Purpose of Cushions on your Hydraulic Cylinders

Aug 25, 2020 2:46:28 PM LEAVE A COMMENT

Cushions much like the ones on your couch right now are designed to take the impact force that comes from the piston moving quickly and abruptly stop when coming in contact with the Head or Cap. While this can happen occasionally without major damage to the cylinder, over time this impact loading can cause the tie rods to fail due to fatigue loading, or can cause excess compression loading to the piston, head or cap. This causes distortion of these parts which will ultimately lead to cylinder failure.

The Unsung Hero: Manufacturing Maintenance Personnel + Four Things That Will Let Them Keep Their Plans Next Weekend

Sep 19, 2016 3:18:40 PM LEAVE A COMMENT

Let’s face it, your maintenance team works hard for you. They put in their eight hours per day, five days per week, and then they are on call the other 128 hours each week that they are not out on the shop floor making repairs. They climb in the machines, deal with all of the dirt and oil, the metal shavings, they go outside to fix the heating system when it is 5° below zero, and are on the roof patching it when it is well over 100° outside.  These guys put in the extra hours when the shop is closed to make sure the machines are up and running every day to keeping the parts flowing out, and the money flowing in. Anything management can do to make their lives easier is ALWAYS appreciated.  When you are looking at purchasing cylinders for your machines that your maintenance team will have to install and maintain, there are some features you need to make sure you get to make their lives easier.

Mar 31, 2016 8:00:00 AM LEAVE A COMMENT

As you crawl out from under your car after loosening and removing the oil drain plug, watching the black oil start to run out into the drain pan you think to yourself, I wonder how many people change the oil when it doesn’t need changing?   You inspect the oil drain plug, it has a magnet on it to attract metal in the oil, as you wipe it on a paper towel you don’t see anything unusual...

Things You Never Knew Halloween Could Teach You About Hydraulic Cylinder Maintenance

Sep 30, 2015 10:30:00 AM LEAVE A COMMENT

It is Halloween night and the goblins are out begging for candy, I hear the door bell and head towards the door to see what is going to be greeting me this time.  After they leave I check my display outside where I have fake blood pumping down a fake corpse lying in a coffin.  The pump spatters a little because some of the fake blood evaporated. As I am adding more 'blood' to my pump I start thinking about work and how a hydraulic cylinder will act if not properly set up...

Ever thought that you have had to go a long way around a design problem to mount a particular component? Here's a hint that might possibly be a ‘quick-fix’ and a help if you're finding yourself in a similar situation.

Sheffer fits tie rod supports to long stroke cylinders to stop the tie rods from twanging like an out of tune banjo - and the design feature does a wonderful job of achieving that aim.

Top 5 Reasons Your Cylinder Supplier Can Make You or Break You

Sep 23, 2013 4:00:02 AM LEAVE A COMMENT

When charged with the notorious "beating your head against a wall", and at the very least unpleasant, task of choosing a cylinder supplier -- one can quickly become disenchanted with all of the industry hype and mumbo jumbo.

From the mammoth sized companies, in which you can get lost and slip through the cracks, to the miniature sized companies that don't offer competitive quality or the same kinds of guarantees as the "big guys" -- the options seem pretty limited.

New, Dirty Oil

May 13, 2013 4:00:39 AM LEAVE A COMMENT

If you’ve ever been drenched with hydraulic fluid during your career in control engineering; you may have remarked on the fact that it’s ‘dirty stuff’! Upon reflection, and when the shock died down, you knew that you were just reacting to a situation and really using the words incorrectly. However, when you look more deeply into the subject of fluids, in certain instances they really can be termed dirty.
