Yes it is. They use deep groove bearings in most radial engines. These types best for reducing friction while carrying both thrust and radial loads

When are ball bearings used?
Generally, a ball bearing is used when speed is important; a roller bearing is used more often when load is most important.
What is the difference between high bypass and low bypass turbofan?
The difference between the low and high bypass turbofans is simply in the amount of air which goes into the engine versus the remainder that goes around (bypasses) the engine. In high bypass engines ( an engine on any large commercial jet) only 20% around 20% of air goes into the engine with 80% bypassing it. (The 80% generates most of the engine thrust) In low bypass engines, this ratio is much lower
What is the motor that converts thermal energy to mechanical energy?
The generic term is "heat engine". Most engines - for example, car engines - are in this category.
What way does an engine rotate?
Most engines rotate clockwise when viewed from the front or opposite side of the transmission.
Why cross-head bearing lubrication most difficult very important?
The force is always down wards, lubrication is a big problem. The relative motion between the x head pin and bearing will never allow to form a thin film lubrication as their relative motion is only for few degree and that too never in one direction
How does the biplane create thrust?
Most biplanes had radial engines driving a propeller, this created thrust when it rotated.
What is the difference between axial bearing and radial bearing?
In axial bearing the most power force in the same direction as the axis of the shaft In radial bearing no.
How many pounds of thrust does an airplane put out?
it depends on the airplane's chosen engines. engines can range from a few thousand lbs of thrust to around 50,000 lbs of thrust. most commercial jets pull out around 30-45,000 lbs of thrust
Which of the following components help to limit the front-to-back movement of the crankshaft?
The thrust bearing in most engines.the cam bearing
What is a radial engine?
There were basically two types of aircraft engines, in-line and radial. In-line engines were like most car engines. You start with a solid block of metal and bore large holes in it for the pistons, one hole behind the other, all in a row. Normally these had to be water-cooled, adding an extra vulnerability to the airplane. A bullet through the radiator would soon cause all the coolant to leak out and soon the engine would seize up from overheating. Radial engines have the cylinders bolted on around the outside, like spokes on a wheel. They radiate from the middle, hence radial. Radial engines are roughly round, and wide when compared to an inline engine, but short, front to back. Because the cylinders are outside, all around the edge, not in the middle of a cylinder block, radial engines can be air-cooled. Think of the nose of a US P-47 - its blunt and wide because of its large radial engine housed there. The US P-51 had an in-line engine, and a pointy nose. The same with Germany's Bf 109 - pointy, inline, and the FW 190, blunt, wide, radial.
Why do all World War 2 carrier planes have radial engines?
They didn't. All American carrier planes had radial engines but some Japanese and British aircraft had liquid-cooled engines, also planes built in Germany for their carrier which was never finished had liquid-cooled engines. Radial engines were used in most cases because they were more rugged than other engines, a pilot would only need to watch his oil pressure gauge whereas using a different engine he would also have to check his coolant, and a single bullet in a liquid-cooled engine could cause it to seize up in a short time.
Does an aeroplane have two engines?
It can have any number of engines of as many different types as needed. For example the B-36 bomber was originally designed with six radial 28 cylinder piston engines driving pusher propellers. Later four small jet engines were added, making it the airplane with the most engines of any mass-produced aircraft ever built. For some airplanes optional jet-assisted takeoff or rocket-assisted takeoff drop away engines can be added for increased thrust at takeoff without extra weight of those engines while in the air in normal flight.
What must airplanes and rockets do to fly through the air?
They must have sufficient thrust from their engines and lift from their wings to overcome their weight and the aerodynamic drag forces. Most rockets do not have sufficient wings to lift them but their engines provide a thrust force that is greater than their weight and it keeps pushing them vertically in the air.
How do you identify roller bearing by number?
Bearing Identification AFBMA Bearing NumbersThe Anti Friction Bearing Manufacturers Association has a code system which identifies bearings by type, size and construction. Any bearing supply house or bearing manufacturer can identify their bearings from such code numbers.

Most adult echinoderms have symmetry?
No. Most have radial symmetry. No. Most have radial symmetry.
What is the different between axial turbocharger and radial turbocharger?
An axial compressor uses many stages of "fans" with stators to compress air in the same direction as its original flow. An example of this is that of *most* turbojet engines' compressors. A radial (or centrifugal) compressor works at right angles to the airflow's original direction. An example of a radial compressor is the compressor on an automotive turbocharger.
Is a snail shell radial?
Yes, most snail shells are radial or have radial striations. There are a large variety of snail shell styles, but almost all have radial aspects.
