Three directions of bearing load

Radial load
axial load
combination load

1

Many factors affect the bearings ability to carry a load such as....

Area of contact
direction of load
loaded zone

2

Some types of bearings are more suited for high speeds and lighter loads, while others are more suitable for what.....

Heavier loads and lower speeds

3

What is the most common ball bearing and what is its nickname

Single row deep groove ball bearing commonly called a Conrad bearing

4

What is the difference between a maximum capacity deep groove ball bearing and a single row deep groove ball bearing

The maximum capacity deep groove has more balls to take heavier loads radially

5

Double row deep groove ball bearing can take higher loads where...

Radially

6

internally self aligning ball bearing is good for what purpose

To align a shaft that must operate at high speeds with extreme accuracy

7

The spherical seat on the outside of the outer ring on an externally self aligning ball bearing allows for what

Misalignment

8

Which bearing accommodates both radial and thrust loads

Single row angular contact ball bearing

9

What are the three arrangements for a single row angular contact ball bearing

Face-to-face
tandem
back to back

10

Face-to-face and back to back arrangements can handle reversing axial loads... What can the tandem arrangement handle

Tandem arrangement can only handle axial load in one direction

11

Is it true that the double row angular contact ball bearing can take heavier radial and axial loads in both directions

Yes

12

Why does a four point angular contact ball bearing have a split inner ring

To accommodate the assembly in some machines

13

What can the four-point angular contact ball bearing only be used for so the load does not run on the split

Combination or axial loads

14

The ball thrust bearing is designed for what load only

Thrust load

15

List four Roller bearing shapes

Cylindrical
needle
tapered
spherical

16

List the four types of roller bearings

Cylindrical
needle
tapered
spherical

17

The spherical shape has a larger load area of contact in a ball bearing of the same diameter which gives it a greater what....

Radial load capacity

18

Cylinder roller bearings handle a small amount of what....... because the raceway is slightly spherical

Misalignment

19

The inner ring of a single row tapered roller bearing is called what

The cone

20

The outer ring of a tapered roller bearing is called what

The cup

21

A 6201 bearing would have a bore of and why
5mm
10mm
12mm
17mm

12mm
because the last two digits are 01

22

What does the K mean in a bearing number
12 to 1 tapered bore
30 to 1 tapered bore
Shielded on both sides

A 12to1 tapered bore

23

And in properly placed ground while welding on equipment is likely to cause what bearing damage
Contamination
Corrosion
Pitting
Spalling

Pitting

24

What is the meaning of C3 in a bearing suffix
Tolerance smaller than normal
Clearance smaller than normal
Clearance greater than normal

Clearance greater than normal

25

Sealed bearing should never be heated above what temperature

175°F or 80°C
