1. The start torque starting torque

Make a bearing ring or the washer relative to other fixed rings or washers began to rotate the required torque.

2. The rotating torque running torque

When a bearing ring or washer rotating, prevent another ring or washer movement required torque.

3. The radial load radial load

Acting on the vertical load bearing axis direction.

4. The axial load axial load

Effect of parallel load bearing axis direction.

5. The static load the static load

When the bearing ring or the washer relative rotation speed is zero (radial or thrust bearings) or when the rolling elements in rolling direction without movement (linear bearing), effect on the bearing load.

6. Dynamic load dynamic load

When the bearing ring or the washer relative rotational (radial or thrust bearings) or when the rolling elements in rolling direction (linear bearing), and the effect on the bearing load.

7. The equivalent load equivalent load

Theory of computation load in general terms, on certain occasions, bearing under the effect of the theory of load as under the actual load.

8. The radial (axial) basic static static load rating, basic radial (axial) load rating

And rolling element and raceway of the total permanent deformation of the corresponding radial static load axial static load (center).If under zero load, the roller and raceway (roller bearings)/assumed as normal bus (full contact), under the maximum contact stress, the rolling element and raceway contact point of total permanent deformation of 0.0001 times the diameter of the roller.For single row angular contact bearings, radial load rating to cause bearing ring each other purely radial displacement of the load of the radial component.

9. The radial (axial) basic dynamic load rating, basic dynamic radial (axial) load rating

Constant radial load (constant axial load center), under the load of rolling bearing theory basic rated life can withstand 1 million RPM.For single row angular contact bearings, the radial load rating to cause bearing ring each other purely radial displacement of the load weight.

10. Life refers to a set of bearing life

Bearing a ring or a washer or a rolling element material fatigue before expansion appeared for the first time, a ring or a washer relative to another ring or a washer revolutions.Life can also be used in a given constant speed operation hours.

11. But * (refer to the bearing life) reliability

Under the same conditions of the rolling bearing in the operation of a group of almost the same expectation reach or exceed a certain percentage of specified life of bearing.A set of bearing can * sex for bearing the probability of reach or exceed the specified life.

12. Rated life rating life

With radial basic dynamic load rating or axial basic dynamic load rating based on the predictive value of life.
13. The basic rating life basic rating life

Associated with 90% can * rated life.

14. Life factor life factor

In order to get the specified life corresponding to a given basic dynamic load rated radial or axial dynamic load rating, applied to the correction coefficient of equivalent dynamic load.

15. Arrange ushering bearing plummer, block

The centripetal bearing with a combination of a component, with the bearing axis parallel to the surface of the support for mounting screws on the bottom.

16. Vertical seat plummer, block housing

Packed with rolling bearings.

17. Flange a flanged housing

A radial flange and in with the bearing axis vertical bearing surface for the installation with the screw hole of a mountain.

18. The tight sleeve adapter sleeve

A cylindrical inner hole axial split sleeve, the outer surface of the conical external thread and small.For there will be a taper hole of bearing installation (with a lock nut and lock washer) in a cylindrical outer surface on the shaft.

19. The withdrawal of withdrawal sleeve

A cylindrical inner hole axial split sleeve, the outer surface of the conical and big end has an external thread.For there will be a taper hole of the bearing on the cylindrical outer surface shaft (nut) installed or removed.

20. Lock nut locknut

A cylindrical outer surface and axial groove nut, with a paw and lock washer ring wrench nut lock.Used for rolling bearing axial positioning.

21. Lock washer lockwasher

There are many claw sheet steel gasket.Outside a claw for lock nut, a claw inserted into the set set or shaft axial slots.

22. The eccentric sleeve eccentric locking collar

Relative eccentric inner hole at one end groove rims, installation of outer spherical bearing inner ring equal elongation of the end.Relative inner ring rotating eccentric sleeve with the inner ring is tight, then tighten the top wire to make it tight on the shaft.

23. One set of concentric locking collar

Installation of outer spherical bearing inner ring on the wide rim, covered wire screwing in the hole on the inner ring and contact with the shaft.
