1. Starting torque
The torque required to start the Bearing Torque rotation of one bearing ring or washer relative to another fixed ring or washer.
2. Rotating torque
When one bearing ring or washer rotates, the torque required to Bearing Torque prevent the other ring or washer from moving.
3. Radial load
Load acting in the direction Bearing Torque perpendicular to the axis of the bearing.
4. Axial load
The load acting in the direction Bearing Torque parallel to the axis of the bearing.
5. Static load
The load acting on the bearing when the relative rotation speed of the bearing ring or washer is zero Bearing Torque (centripetal or thrust bearing) or when the rolling element has no movement in the rolling direction (linear bearing).
6. Dynamic load
The load acting on the bearing when the bearing ring or washer rotates relative to each other (centripetal or thrust bearing) or when the rolling Bearing Torque element moves in the rolling direction (linear bearing).
7. Equivalent load
A general term used to calculate the theoretical load. On a specific Bearing Torque occasion, the bearing bears the actual load under the action of the theoretical load.
8. Basic static radial (axial) load rating
Radial static load (central axial static load) corresponding to the total permanent deformation of rolling element and raceway. Under zero load, if the roller and raceway (roller bearing) are or are assumed to be normal bus (full line contact), under large contact stress, the total permanent deformation at the contact between the rolling element and raceway is 0.0001 times the diameter of the rolling element.
For single row angular contact bearings, the radial rated load is the Bearing Torque radial component of the load causing the pure radial displacement of the bearing rings relative to each other.
Constant radial load (constant central axial load), under which the rolling bearing can theoretically withstand the basic rated life of 1 million revolutions. For single row angular contact bearings, the radial rated load is the component of the load causing the pure radial displacement of the bearing rings relative to each other.
10. Life (of a set of bearings)
The number of revolutions of one ring or washer relative to another ring or washer before the first fatigue expansion of the material of one ring or washer or rolling element of the bearing. The service life can also be expressed by the number of operating hours at a given constant speed.
11. Reliability (referring to bearing life)
The percentage of a group of nearly identical rolling bearings operating under the same conditions that are expected to reach or exceed a Bearing Torque specified service life. The reliability of a set of bearings is the probability that the bearing reaches or exceeds the specified life.
12. Rated life
Predicted value of life based on radial basic rated dynamic load or axial basic rated dynamic load.
13. Basic rating life
Rated life associated with 90% reliability.
14. Life factor
In order to obtain the basic rated radial dynamic load or basic rated Bearing Torque axial dynamic load corresponding to a given rated life, the correction factor applicable to the equivalent dynamic load.
15. Plummer block with seat bearing
A component of a radial bearing combined with a seat. There is a base plate for installing screws on the support surface parallel to the axis of the bearing.
16. Plummer block housing
Install the seat for rolling bearing.
17. Flange housing
A seat with a radial flange and a screw hole for its installation on the support surface perpendicular to the axis of the bearing.
18. Adapter sleeve
A sleeve with an axial opening with a cylindrical inner hole has a conical outer surface and an external thread at the small end. It is used to install the bearing with taper hole (with lock nut and lock washer) on the shaft with cylindrical outer surface.
19. Withdrawal sleeve
The outer surface of a sleeve with an axial opening of a cylindrical inner hole is conical and the large end is provided with an external thread. It is used to install or remove the bearing with tapered hole on the shaft with cylindrical outer surface (with nut).
20. Lock nut
For the screw nut with cylindrical outer surface and axial groove, use an outer claw of the lock washer and an annular wrench to lock the nut. Used for axial positioning of rolling bearing.
21. Lock washer
Sheet steel washer with many external claws. An outer claw is used to lock the nut, and an inner claw is inserted into the axial groove of the locking sleeve or shaft.
22. Eccentric locking collar
One end is provided with a groove steel ring eccentric relative to the inner hole, which is installed at the equally eccentric extension end of the inner ring of the outer spherical bearing. Rotate the eccentric sleeve relative to the inner ring to fix the inner ring, and then tighten the jacking screw to fix it on the shaft.
23. Concentric locking collar
The steel ring installed on the wide inner ring of the outer spherical bearing is screwed into the hole on the inner ring and in contact with the shaft.
