Anti-Friction Bearings Flashcards
To check the concentricity of a bearing housing bore, check the diameter with a ______ gauge in at least 3 locations.
Telescoping
You can inspect a shaft for straightness by placing it in a lathe and checking for concentricity with a ______ indicator.
Dial
If the inside of a bearing is discolored, it is likely due to ______.
Overheating
If the bearing raceway has tracks that appear as axial lines that have the same spacing as the rolling elements, then the likely cause is _______ acring.
Electrical
Hot mounting a bearing is most practical for bore sizes over _____ mm.
20
Hot mounting a bearing usually involves heating a bearing to ______ degrees C.
80
Never heat a bearing above ________ degrees C.
120
Bearing _______ clearance is the total amount of clearance between the rolling elements and the raceway.
Internal
_____ clearance is the internal clearance (Radial or axial) before the bearing is mounted
Initial
_________ clearance is the internal clearance (radial or axial) after the bearing is mounted.
Residual
_________ clearance is the internal clearance (radial or axial) in a bearing when it is running at its operating temperature.
Running
When bearing internal cleance is measured by placing a dial indicator on the outer ring and moving it while holding the inner ring, it is called a _______ check.
lift
_______ is the load that the rolling elements are under before any external load is applied.
Preload
The surface on which the rolling members roll is called the ______.
Raceway
The _______ or separator prevents the rolling elements from rubbing against each other.
Cage
The cage or separator push the rolling elements through the ______ zone.
Unloaded

Under load, a ball bearing shape changes from spherical to ______.
Elliptical
If the load on a bearing is at 90 degrees to the shaft centre line, it is called a ______ load.
Radial
If the load on a bearing is parallel to the shaft centre line, it is called an _______ load.
Axial
A _____ load on a bearing is both radial and axial.
Combination
A _____ load bearing had 100% loading on all rolling elements at the same time.
Thrust
A higher radial load bearing ______. A high radial load bearing _____.
Maximum capacity deep groove ball bearing, Deep groove ball bearing.
A self-aligning bearing have a _____ seat on the outside of the outer ring.
Spherical
