Bearings

Front 1

bearing load is divided into what three types?

Back 1

radial
thrust
radial thrust

Front 2

what are the two main types of bearings?

Back 2

plain bearing
anti-friction bearing

Front 3

roller bearings come in what three distinct shapes?

Back 3

cylindrical
tapered
barrel

Front 4

thrust bearings cannot support what kind of load?

Back 4

radial

Front 5

although bearings are designed to be extremely rugged, they are very sensitive to what three things?

Back 5

corrosion
contamination
abusive handling

Front 6

the hand can usually be held in contact with a surface below ? degrees fahrenheit

Back 6

131

Front 7

if temperature rises immediatly after start up in a grease bearing application...

Back 7

it is most likely grease has slumped ino the races. stopping the unit and allowing te grease to cool in the channeled state will usually cure this condition

Front 8

if the temperature rises immediatly after the bearing has been lubricated with grease..

Back 8

the cause may be excessive quantity if grease or the wrong type..to avoid this condition, follow the correct lubrication procedure for both quantity and type

Front 9

if the bearing is overgreased..

Back 9

remove the drain plug and allow the excess to drain

Front 10

if there is excessive loading of the bearing, excessive bearing preload, excessive shaft or housing interference, or external bearing overload...

Back 10

check alignment during mounting and check for tight-fitting seals.

Front 11

what are ten common problems associated with bearing failures?

Back 11

scratching
erosion
grooving
plowing
shallow embedment
deep embedment
corrosion
electrolytes
organic acids
cavitation

Front 12

in bearings, what can cause false brinelling of the races?

Back 12

the wearing away of material due to vibratory motion during storage or transport and corrosion due to lack of preservation compound on bearing surfaces
