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...

Cylinder Mounting & Column Loading

“I need 100,000 pounds of force on a 120” stroke with a 2” diameter piston rod and clevis mount.” A click and then there is no one on the other end of the phone.

Cylinders convert a fluid pressure into a mechanical force.  The input fluid pressure acts on the surface area of the cylinders piston displacing it to create a linear movement of the piston rod.

How To Avoid Cylinder Side Loading: 4 Ways to Compensate for Less Than Proper Cylinder Alignment

Apr 8, 2014 8:00:00 AM LEAVE A COMMENT

When installed with proper alignment, fluid power cylinders will provide the smooth trouble free performance for which they were intended.  Unfortunately, perfect alignment is extremely difficult, if not next to impossible to achieve. During cylinder operation, any misalignment can impose an eccentric force on the piston rod known as “side loading”.

Any piece of equipment operates best when it is used regularly within normal guidelines.

Take for example a classic car; it ran perfectly when you put it away last fall, but something happened during the long winter.

Multiple Mountings: Magic or Misery?

Nov 22, 2013 3:00:52 AM LEAVE A COMMENT

In our experience, the call for more than one mounting feature on a cylinder is by no means a rare event.

We won’t say that all mounts can be combined; as clearly there are some features which would just interfere with each other. For instance, a Front Head (FHF) and a Side Lug (SL) cannot coexist on the same end of a cylinder. What is possible, however, is to have an FHF (Head) mount combined with a Side Lug at the Cap; if that serves a useful design purpose for you.

A Handy Platform

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.

Hydraulic and Pneumatic Boosters: How Do They Work and What are They Good for?

Oct 21, 2013 4:00:00 AM LEAVE A COMMENT

Boosters or intensifiers are used to create a high pressure output from a low pressure input. Much like how an electrical transformer works by trading current for voltage, a hydraulic booster transforms a larger volume of low pressure fluid into a smaller volume at a higher pressure.
