A shaft coupling is a cylinder device that connects two shafts together in order to transmit power. They are found in many different types of machinery such as power transmissions, drive shafts, generators, wheels, pumps, line shafts, construction equipment, automotive engines, and many more. There are many different types of shaft couplings that are used based upon the type of machine and how much power and movement the shafts need to be capable of. A few types are rigid couplings, sleeve couplings, clamp or split-muff couplings, flexible couplings, diaphragm couplings, disc couplings, gear couplings, oldham couplings and jaw couplings among many others. They are an essential part of many machines in order for them to work properly.

When I was in high school every classroom was equipped with a mechanical pencil sharpener. Most of the sharpeners worked and were well used but occasionally some kid got the idea it would be funny to stick a tootsie roll in one of them. Mechanical pencils are making pencil sharpeners somewhat obsolete but there will always be a need to sharpen colored pencils or number two pencils for scantrons. Personally, no mechanical pencils will ever replace the Mirado Black Warriors. It was always fun to stand in the corner, interrupting the teacher with the loud grinding noise that pencil sharpeners make while they eat at a pencil.

Today we use precision ball bearings for a variety of different things. Precision ball bearings help make sure that there is a high degree of control and predictability of movement. Ball bearings are the most commons means by which such friction reduction is accomplished. But it was not always this way. There was a very simple start to the precision ball bearings that we see today. Yes, before miniature bearings, roller bearings, steel ball bearings, and thrust bearings there were simply bearings. Old wooden rollers that supported objects like how precision bearings do. Some historians would say that the invention of bearings may even possibly predate the invention of the wheel. The oldest history of bearings starts with the Egyptians and how they used roller bearings.

A double acting cylinder is actually used in more applications than a single acting cylinder. There are many reasons for this, dealing with the superiority of double protection and drive versus single. However, if you have the choice between a single and double acting cylinder, here are a few reasons why you should always choose the double cylinder:

When a manufacturing company produces products that are able to be utilized in a wide variety of industrial arenas, they can choose one of two paths as far as the variety of the models they make goes. The first marketing technique would be to produce products that can be used in a number of different industrial contexts, which would require a number of designs and options so that all needs could be met, and a very generalized marketing strategy so that any industry could see themselves buying the products. The other strategy involves choosing a target audience and arranging marketing techniques towards them alone. Specializing in the types of products used by one specific industry alone can improve hits on websites and calls and purchases made.

The earliest springs were not coil springs like we think of them today. Ancient people used flexible branches and plants to act like a spring mechanism to trigger traps and other simple devices. In the Bronze Age, people began making simple metal springs, such as tweezers and metal leaves that could act like a spring inside padlocks and even to power machines like catapults.

A clock spring is different from the rounded, coil springs of today. These springs are flat, spirals of metal that are used to provide rotating tension on an object such as a clock mechanism or timers. There are three main kinds of clock springs that have their own particular uses and benefits.

A coil spring manufacturer makes many kinds of springs, all with their own advantages and disadvantages. The grouping of coil springs as a whole offers a large range of benefits that make them ideal for use in many industries, from to production to furniture making. If you have the choice between a coil spring and another kind of spring, consider the following advantages of coil springs before making your final decision:

A linear actuator is a device that turns non-linear motion, or movement that does not go back-and-forth, into linear movement, or motion that does go back-and-forth. There are different varieties of linear actuators, and they range in size, power, and use. The specific type called a DC actuator, for example, is usually used in conjunction with a DC power source in order to function properly. We often see these kinds of actuators in smaller devices that require batteries. The DC actuator is part of a larger family of linear actuators called electric actuators.

Dovetail slides offer economic and simple solutions to machine builders and users, guaranteeing precise movement and tooling positioning for special machine and/or OEM product lines. The base and saddle of the slides are generally constructed from close-grained cast iron and are normalized to prevent distortion. Designed to ensure accurate, smooth and reliable performance, dovetail slides usually have large contact areas. This large contact area means they offer higher stiffness and load bearing capacity than other types of slides. Dovetail slides have many benefits over other slides, and some of these benefits are suited to specific applications. I’d like to discuss some of these benefits as well as considerations in terms of suitability for certain applications.

Electric motors are useful for a number of reasons and are necessary where fuel powered motors cannot perform. Many electric motors are restricted by operating on either alternating current (AC) or direct current (DC) power. However, universal electric motors are capable of operating using both AC and DC power. So, why are some electric motors limited by either AC or DC and what makes universal motors different? Many items used frequently if not daily have universal electric motors that power them. They are utilized because of a vast amount of advantages, but like all things there are also some disadvantages.
