What is a bushing used for?
A bushing is called by many different terms. It can be referenced as a plain bearing, solid bearing, friction bearing, or slide bearing. They are used in many different industries and machinery. The use of bushing is to reduce the friction, vibration, and noise that machinery might create.

What are plain bearings (bushings)?
Types of Plain Bearings (Bushings) A plain bearing, also known as a bushing, is a mechanical element used to reduce friction between rotating shafts and stationary support members. Typically, a bushing relies on soft metal or plastic and an oil film to support the rotating shaft on the hardened shaft journal.

When should a reducer be used?
If your ducts have the same diameter you will simply use a male connection piece. However, what if you are going from a 150mm diameter duct to a 100mm one? Well, in that case, you will need to use a reducer. These fittings may be used when there is a single diameter change or multiple diameter changes.
What are the two types of reducer?
There are 2 types of standard reducers available: concentric and eccentric reducers. The concentric one, which resembles a cone, is used to join pipe sections on the same axis. The eccentric type has an edge which is parallel to that of the connecting pipe, which allows it to align with one side of the inlet.
What is the purpose of a pipe reducer?
What is a Pipe Reducer? First, let's keep it simple: A pipe reducer is a pipe fitting that connects a larger pipe to a smaller pipe. Thus, it reduces the size of the pipe in the pipe system, from one size to another. Pipe reducers may frequently be used to connect pipes of different sizes.
What is the difference between a reducer and a coupling?
For example a 15mm to 10mm reducing coupling accepts a 15mm pipe into one end and 10mm pipe into the other. A 15mm to 10mm fitting reducer accepts a 10mm pipe into one end and the other end goes inside a 15mm fitting such as an elbow or coupling or tee.
What is meant by reducer?
a person or thing that reduces.
What is a pipe reducer called?
An eccentric reducer is a fitting used in piping systems between two pipes of different diameters. The same fitting can be used in reverse as an eccentric increaser or expander.

A rolled rim provides added grip while the elongated neck and teeth on the washer, also known as a spur washer, add reinforcement and reduce rotation so you can use these grommets in thick materials such as canvas. Press the grommets into a hole you've already cut. They strengthen and prevent holes from fraying in tarps, covers, and curtains. They also provide a way to run rope and cable ...

How are journal bearings designed?
The design of hydrodynamic journal bearings takes into account the viscosities of oils, oil film thicknesses, coefficients of friction , oil flow rates, oil leakages, etc., in addition to the parameters of shaft load and speed. Thus hydrodynamic journal bearing design is heavily dependent on the makers of journal bearings who often provide journal bearings as housed units complete with seals and il lubrication. Oil lubrication is often provided by the use of oil rings. Sleeve bearings are sized according to pressure and velocity considerations, which together determine the so-called PV limit. This represents the upper limit of the combined pressure and velocity for the given bushing material. The bearing is sized to operate below this threshold. The calculation involves projecting the area of the bearing based on its inside radius and length. Some manufacturers identify maximum loads and speeds for their individual sleeve bearing sizes, relieving designers of the need to calculate them. Fitting of plain bearings is critical as press fits are usually used to keep the bearing intact. Pressing a bearing into place can distort the geometry of the bore and cause problems in developing the fluid film profile, making the bearing wear out quickly. Manufacturers of plain bearings can offer guidance to fits to ensure the bearings run properly. Some bearings require a run-in procedure as well, especially some of the so-called dry-running plastic bearings. Grooving of bearings is often done to add pockets for holding lubricant for bearings that run near speeds below the hydrodynamic regime. Many standard groove patterns can be machined into stock bearings, and these patterns range from the very simple circular, straight, or loop cuts to complex combinations and multiples of these simple shapes. Spherical bearings are selected based on allowable loads and misalignment angles. Drill jig bushings are more concerned with accuracy than load and are generally chosen based on these parameters.
What are sleeve bearings made of?
Sleeve bearings are often made of bearing bronze either sintered or cast and sometimes filled with plugs of lubricant such as graphite as with the bearings at left. Various plastics are also popular for sleeve bearings. Sleeve bearings are offered in two primary styles, a plain cylindrical version which is pressed flush into a component, ...
How do engine bearings work?
Main engine bearings operate mostly in what’s called the hydrodynamic regime, meaning that under normal conditions the journals and bearings are separated by an oil wedge formed as the shaft rotates . Oil is pumped into the bearing through feed holes that distribute oil to the main and connecting rod bearings.
What is a plain bearing?
A plain bearing, also known as a bushing, is a mechanical element used to reduce friction between rotating shafts and stationary support members. Typically, a bushing relies on soft metal or plastic and an oil film to support the rotating shaft on the hardened shaft journal. Plain bearings are used primarily in machinery that has a rotating or a sliding shaft component. Also called a journal bearing, sleeve bearings, or sliding bearings, plain bearings have no rolling elements. Some are made of relatively soft metal, such as Babbit, to protect the shaft journals. They are made of other materials as well, depending on the application and load requirements. Other bushings may be used for alignment jigs in drilling operations.
What is a spherical roller bearing?
They are distinct from spherical roller bearings, which are rolling element bearings addressed in the family Bearings. Generally, for spherical bearings, the spherical inner race rotates angularly within limits in the outer race while grease, PTFE, etc. provides a lubricating layer between sliding surfaces.
What is a drill bushing?
Drill jig bushings provide drill guidance during precision metal drilling operations and are ordinarily available as press-fit single parts or as two-piece renewable components that use replaceable liners. Bushings of this kind serve more for guidance than support and are often made from harder steels than bushings designed to function as bearings. They are usually very tightly toleranced to maintain the accuracy needed for machining operations.
What are rubber bushings made of?
Some are made of relatively soft metal, such as Babbit, to protect the shaft journals. They are made of other materials as well, depending on the application and load requirements. Other bushings may be used for alignment jigs in drilling operations. An example of plain rubber bushings. Image credit: Thomas A. Caserta.
