To get the true bearing from a compass (magnetic) bearing you must add the variation (for your location) to the compass bearing.
The supports that are used to hold a rotating shaft in position. Small internal combustion engines such as those used to power model aircraft often use phosphor bronze for the main crank bearings.
bearingless rotor Rotor in which flapping, lead/lag and pitch change movements are provided by the flexibility of the structural material and not by bearings. No rotor is truly rigid.

Lower Bearing: No leaks
I find the lower bearing a difficult part to describe a preflight procedure.
Technology / Motors / Thrust Bearings: Special bearings used to handle higher than normal axial forces exerted on the shaft of the motor as is the case with some fan or pump blade mountings. MORE
Bearing & Track
Track is where the aircraft is going. Bearing is the direction to or from a feature or navigation aid.
Bearing can also be expressed relative to the nose of the aircraft via the clock code or as a number of degrees.

in which bearing means:
The horizontal direction to or from any point, usually measured clockwise from true north, magnetic north, or some other reference point through 360 degrees.
Magnetic bearing (MB). The direction to or from a radio transmitting station measured relative to magnetic north.
Magnetic heading (MH). The direction an aircraft is pointed with respect to magnetic north.

Detail: Load Bearing MountThe weight and torque of the engine are conveyed to the craft's stringer through a transverse steel weldment bolted to the stringers.

A magnetic bearing from a VOR, TACAN, or VORTAC facility, except for facilities in the Northern Domestic Airspace which may be oriented on True or Grid North.
QDR: magnetic bearing from the station.
QFE: atmospheric pressure at aerodrome elevation. With its sub-scale set to the aerodrome QFE an altimeter will indicate height above that airfield.
QFU: magnetic orientation of runway in use.
You are on the 068 bearing, whereas you are supposed to be on the 078 bearing. You must get back on course. For starters, "double the error", in other words you are 10 degrees off course, turn right 20 degrees to a new heading of 100.
The shape of a load-bearing component can be critical. As an example, I sometimes ask people if they believe that a few ounces of low grade aluminum can support my 230 plus pounds.

The hinge pins are kept in their bearings by the cotter-pins, inserted through the drilled holes in the bottom of the hinge pins.

The trunnion is splined to the mast and has two bearings through which it is secured to the yoke. The blades are mounted to the yoke and are free to teeter (flap) around the trunnion bearings.
If you are not flying by reference to VORs, but rather using GPS to fly from waypoint to waypoint along an airway, do not be surprised if your GPS indicates a bearing that differs from the charted VOR radial for that airway.
You then center the CDI (Course Deviation Indicator) or needle on your OBI (Omni-Bearing Indicator) with a TO reading, and the most direct heading to the station can be read at the top of the instrument, ...
The conditions under which the flight is conducted (hot, bouncy, low ceilings, etc.) have a bearing, but in general, we should set limits with which we are comfortable.
Because ATC is involved in the movement of all commercial airline aircraft, the capabilities and efficiencies of ATC has a direct bearing on the schedule performance of the airlines.
Direction is indicated to the pilot as a magnetic bearing or as a relative bearing to the longitudinal axis of the aircraft depending on the type of indicator installed in the aircraft.
They provide a bearing to and from the NAVAID as well as magnetic direction. Non-directional beacons (NDB) are another from of NAVAID used but these are more so for approaches.

The aircraft's position is displayed as a function of its magnetic bearing "to" or "from" the VOR station. Pilots can then track toward or away from the station while monitoring their course along that individual VOR radial.
A few drops of oil should be applied to the hinges periodically and if the aileron is removed for any reason, oil and graphite should be introduced between the hinge pin and its bearing.
