MD - Design of Bearings

What does the term "static load carrying capacity" of a bearing refer to?

• Maximum load the bearing can carry while in motion

• Maximum load the bearing can carry without any motion

• Maximum speed the bearing can handle

• None of the above

Dynamic load carrying capacity of a bearing is associated with:

• Rotational speed of the bearing

• Load applied to the bearing while stationary

• Lubrication quality

• Bearing material

Which factor is critical for determining the static load capacity of a bearing?

• Bearing size

• Rotational speed

• Material composition

• Lubrication type

In bearings, what does the term "dynamic load" refer to?

• Load applied to a stationary bearing

• Load applied to a moving bearing

• Load applied to a vertical bearing

• Load applied to a horizontal bearing

Which parameter is crucial for calculating the dynamic load rating of a bearing?

• Bearing size

• Static load capacity

• Rotational speed

• Lubricant viscosity

The dynamic load rating is defined as the load at which the bearing has a life of:

• 100 hours

• 1,000 hours

• 10,000 hours

• 1 million revolutions

Static load carrying capacity is more relevant in situations involving:

• High-speed rotation

• Low-speed rotation

• Oscillating motion

• Continuous oscillation

What does "L10 life" refer to in the context of bearings?

• The expected lifespan of the bearing under static load

• The expected lifespan of the bearing under dynamic load

• The maximum speed the bearing can handle

• The load rating of the bearing

Which factor is critical for minimizing the wear and tear of bearings under dynamic loads?

The load rating of a bearing is often specified for a certain:

• Load direction

• Temperature range

• Lubricant type

• Manufacturing process
