The ISO basic number for each standard antifriction Bering includes information about its

Bore size bearing size bearing series

1

A external self aligning ball bearing gets its misalignment capabilities

A Spherical seat between the outer ring and the outer housing

2

What does the suffix K mean

At 12 to 1 tapered bore

3

Sealed bearing should never be heated above

80°C or 175°F

4

What is the meaning of C3 in the Bering suffix

Clarence greater than normal

5

What with the fit chart reading of k6, 4L – 6T tell you

Bearing bore shaft transition fit

6

You are mounting spherical roller bearing with the tapered bore what would be the installed clearance be if the bench Clarence is .006 inches

.003 inches

7

List three states of lubrication

Boundary lubrication
Mixed film lubrication
Hydrodynamic lubrication

8

List the four main parts of a single row deep groove ball bearing

Cage
Race Ways
Rolling elements
Outer and inner rings

9

How could you visually identified the maximum capacity ball bearings

The large area of contact the larger The load capacity of the Bering this is because the load distributes over a larger area

10

What is the internal clearance in a Spherical roller bearing called prior to installation

Bench clearance

11

What functions do shields perform in antifriction bearings

To keep dirt out of the Bering

12

What function do seals perform in the antifriction bearing

Keep dirt out of the Bering also there's a small gap between the shaft and the seal to allow lube to ride

13

What is the function of the grooves cut into the outer circumference of the outer ring of some antifriction bearings

To allow for lubrication to be injected

14

What feature would indicate an internally self aligning bearing

Spherical outer race

15

What are the three types of fits

Clearance
Transition
Interference

16

List three factors that could influence the type a bearing selected for an application

Area of contact
Direction of load
Load zone

17

Define axial load

Runs parallel to the journal or shaft

18

Define radial load

Runs perpendicular to the shaft or journal

19

Single roll deep groove a ball bearing most commonly called

Conrad bearing

20

Maximum capacity deep groove ball bearing

Is similar to the deep groove ball bearing except that it is assembled with more balls

21

Single roll angular contact ball bearing

Accommodates both radio and trust notes

22

Ball thrust bearing

Is designed for pure thrust load only

23

What does the suffix C-1 through C-5 mean which is the biggest and which is the smallest

Indicates the amount of internal Clarence c1 being the smallest C5 the largest a normal clearance lies between C2 and C3

24

When hot mounting a bearing what temperature should you bring the Bering to about

80°C but never heat above 120°C

25

What kind of load can a single roll angular contact ball bearing

Combination one direction axial

26

What kind of load Can a self aligning ball bearing

Radial

27

What kind of load a single roll tapered roller bearing

Combination or one direction axial

28

What kind of load will a double row tapered roller bearing have

Combination or reversing thrust

29

What kind of load will a needle bearing have

Radial load only

30

Kind of load will a carb bearing have

Radial only

31

Is a common designation for shield

Z

31

What are the common designation for a rubbing seal

RS

31

What type of load can a single roll deep groove ball bearing handle

Combination, two directions
