How to select the right bearing lubricant | Engineering360

May 24, 2019· Oil jet lubriion (also referred to as oil injection) is for extreme speed appliions, such as jet engine bearings. One or more nozzles provide a steady stream of pressurized lubriion oil directly to the bearing. The velocity of the oil must be high enough to break through the turbulence around the rotating bearing. How Ball Bearings

either in main bearing chaers or engine gearboxes. In bearing chaers, air enters sumps through carbon or labyrinth seals and then mixes with lubriing oil supplied to the bearings. This creates a moving oil mist or vent air, which is cycloned in the deoiler. The deoiler recovers oil and directs air overboard.

US8402741B1 - Gas turbine engine shaft bearing

A typical jet engine has two or three spools, or shafts, that transmit torque between the turbine and compressor sections of the engine. Each of these spools is typically supported by two bearings. One bearing, for example, a ball bearing, is arranged at a forward end of the spool and is configured to react to both axial and radial loads.

Ball bearing - Wikipedia

A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races.. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls.
