Bearings Flashcards
When rotating a ball bearing by hand, a regular click indicates
A cracked ring
A journal load is
Radial
What kind of bearing is used in a typical main wheel?
Tapered roller bearing
Spherical roller bearings resist what loads?
Large radial and moderate thrust
Where are needle roller bearings used?
Where there are space restrictions
Loads on tapered roller bearings are
Radial and thrust
A self aligning bearing is a
Radial bearing
A crankshaft would be fitted with a
Plain bearing
Shielded ball bearings are inspected by
Rotating slowly by hand
Thrust bearing take
Side loads
A single row ball bearing is best suited to accepting
Radial loads only
Taper roller bearings are used for what purposes?
To transmit thrust loads with radial loads
The stationary race of a journal bearing is normally
An interference fit
Inspection of bearings is normally carried out
In situ
Damage to the shield of a bearing should result in
Rejection of the bearing
A watermark on a bearing indicates
Intergranular corrosion
Needle bearings accommodate
Radial load only
When silica gel has absorbed moisture the colour changes
From blue to pink
A thrust bearing is designed so that
It transmits axial loads, therefore limiting axial movement
Lubrication of roller bearings and needle bearings are
By hand when operating at low speed
Needle roller bearings
Are susceptible to brinelling
