Here are some more information for Actuator Slide:

Selection of you components in dealing with actuators is ger-mane to reliability. Let's take an example that we need to replace a cylinder (linear actuator), with a like item, however it has not performed well or lasted long at all. There are usually reasons for this, and they are misapplication, inadequate selection process, mis-understand the actual need of the function necessary to perform the task.

OK, here's an example, I have a cylinder that is moving a load 24/7 at a rate of 1 cycle per minute. I am using a 2" bore cylinder (keeping it simple), to push this small load of about 300 lbs. Now a 2" bore cylinder has an area of 3.14 sq in.. Remember force equals area x pressure. Well we know that pneumatics (Air) can only produce about 80-90 psi because of losses in the plant and leaks, etc, etc. If you have only 80-90 psi available this equates to 251-282 lbs of force. The fact that you worked for a while means that you had sporadic episodes of higher pressure.

Get the picture, this was a misapplication in the first place, undersized and designed. To do this work you would need to go to a size of 2 1/2" bore which at 80 psi would give you 490 lbs of force and would do just fine, although I would even go to a 3" bore to gain a reliability advantage. The same thing applies to the rotary actuators which rely on area (square inch area) x pressure to perform the work.

Without getting overly complicated, the above just gives you examples of what and why proper selection and design is so important.

It has been my experience dealing with a lot of so called fluid power vendors, (those with resell rights for certain products) that there are only a select few who actually hire and train their sales engineers to know what you need and can help you with design and troubleshooting.

This article is to caution you as well as explain to you the importance of the above. A lot of people call actuators a commodity item and there are vendors who prey on uninformed clients and customers who just order from them because they have undercut pricing just to get orders.:You have heard of "You Get What You Paid For", is so true in this instance.

Stay tuned for more informative articles on fluid power so I can create a better understanding of how and what is the best path forward to insure the proper application of the products you need.

Lathe. The Parts.

A turn can or cannot have a stand (or legs), which rests on the floor and raises the bed of turn to a height of work. Some turns are small and rest directly on a bench or a table, and do not have a stand. All the turns have a "bed", which is (almost always) a horizontal beam (although some turns of numerical control by computer have a vertical beam so that the bed ensures these chips, or the pieces, falls free of the bed. At an end of the bed (almost always the left, as an operator faces the turn) is a "headstock". The headstock contains the bearings of rotation to high precision. Rotation in the bearings is a horizontal axis, with an axis parallel with the bed, called the "axis".

The axes are often hollow, and have external wire and/or a tape of Morse on the "interior" (C. - with-D., facing towards the right/the bed) in which accessories which are held the object can be assembled to the axis. The axes can also have wire external and/or a taper at their end of "outboard motor boat" (C. - with-D., facing far from the bed), and/or can have a wheel of order or any other additional mechanism on their external end. Axes are actuated, and give the movement to the object. The axis is led, by power of foot by a pedal and a wheel or a belt drive with a source of energy. In few modern turns this source of energy is an integral electric motor, often in the headstock, with the left of the headstock, or under the headstock, hidden in the stand. Some Amish are known to buy the modern turns, remove the electric motor, and then convert them into race via the leather belts of an air line centers.

At the other end of the bed (almost always the line, as an operator faces the turn) can be a tailstock. Not all the turns have tailstocks. A tailstock provides the auxiliary support to the object. Of Tailstocks are not actuated. Turns metallurgical have "slide transversely", which is a flat piece which rests transversely on the bed, and can be started perpendicular to the bed. To rest placed on the slide transversely is a tool post, which holds a cutting tool which removes the material of the object. There can or cannot is not a lead screw, which moves the slide along the bed transversely.

Metal Woodturning and turns of rotation do not have the slides transversely, but have "banjos", which are flat pieces which rest transversely on the bed. The position of a banjo can be adjusted with the hand; no clutch is implied. Assemble banjo vertically is a post of tool, with the top of which a "rest of horizontal tool". In woodturning, tools with hand are attached against the rest of tool and surveys using a lever in the object. Out of revolving metal, the additional pin assembles rest of tool vertically, and is used as point of support against which tools can be raised using a lever in the object.

2002 Ford Explorer temperature controller?

my sons explorer, the temp. controller will slide back and forth but is stuck in the cold mode. I have gotten answers on this site on how to fix the actuator, but I want to know if there is something that I can do temporally to get him some heat for the defrost. we are having a lot of ice right now. thank you

Unfortunately, the blend air door that controls the mix of hot and cold air is pretty inaccessible without removing the entire plenum (not an easy task.) I can think of no easy way to put it in the heat position - this is assuming that the no heat is caused by the controller and not a thermostat or restricted heater core.

Moving Coil Actuator exhibits extended cycle life.
Designed to replace pneumatic cylinders in positioning/measuring applications, LCA series includes 1- and 3-coil versions which respectively generate 10 and 30 N and offer accelerations exceeding 40G. Model LCA25 occupies 25 x 50 mm footprint, and length depends on stroke, which can vary from 10-100 mm with encoder resolutions from 20 micron to 50 nm. Slide option is available for scanning ...
