Bearings Flashcards
0
Q
Properites of angular contact bearings
A
- > high radial loads
- > moderate axial loads
- > axial loads depend on the contact angle
1
Q
types of radial bearing
A
- > Sealed
- > Crowded bearing
2
Q
Properties of thrust bearing
A
- > high axial loading only
- > suited to heavy loads and low rotation
3
Q
Define needle roller bearing
A
- > length is greater than diameter of bearing
- > pure radial loads
4
Q
property of spherical roller bearing
A
-> allows small amount of misalignment
5
Q
what is group 2 bearings
A
- > small radial internal clearance
- > precision work
- > minimum axial and radial movement.
6
Q
what is normal group bearings
A
- > general bearings
- > only one of the rings are in interference fit
7
Q
what is group 3 bearings
A
- > greater radial internal clearance
- > both rings in interference
- > high speed
8
Q
what is group 4 bearings
A
- > largest radial internal clearance,
- > both rings in interference fit
- > high heat
