M6.8 Bearings Flashcards
What are the two major groups bearings are divided into
Plain bearings and rolling element bearings.
What are The two further sub groups that bearings can be divided up into
Ball bearings and roller bearing
What are the two forces that bearings can be subjected to
Axial (along the shaft)
radial (acting at a right angle to the shaft)
What is required to ensure bearings have a longer service life
Lubricants and oils
What’s the downside of plain bearings
They can only carry light radial loads and it requires regular maintenance to avoid contamination
What are the two major types of bearings
Plain bearing
Rolling bearing
What’s better roller bearings or ball bearings and why
Roller bearings as they have a larger contact area meanings they can take higher radial loadings
With rolling element what are the sub categories of bearings
Ball bearings
Roller bearings
What’s the advantage of anti friction bearings over plain bearings
They produce less heat
Lower starting friction
Can carry heavier loads
What is a Axial load
Acting longitudinal ( too the side of the bearing )
What’s the benefit of an air bearing
They provide a zero friction Interface
What is the radial load
Acts vertically, weighing down the bearing
What must bearings have to reach a long service life
Lubrication and maintenance as they get contaminated with fod,filth etc
What’s the strongest type of bearing
Tapered roller bearings
What is synthetic lubed with
Water, also acts as a coolant
