Introduction TIMKEN one-way thrust angular contact ball bearings

TIMKEN bearings arrangement
More suitable for installed in pairs or groups of mounted axial thrust angular contact ball bearings. The bearing seat width tolerance can make exactly the same bearing pairs or groups are arranged side by side (general bearing). Bearing type O and X type arrangement of and bearing preload regulation group
Stiffness and preload
One-way thrust combined arrangement of the angular contact ball bearing steel by layout type and preload their decision. Bearing two O type or X type arranged side by side with a high preload provisions, some bearing the same position alignment bearing preload and stiffness will increase.
The holder
Molding window glass fiber using ball guide one-way thrust angular contact ball bearing reinforced polyamide cage (suffix TVP). The holder can accommodate a large number of steel balls. Cage material good sliding properties and good lubrication holder groove can make the bearing low friction operation.
Lubrication
TIMKEN one-way thrust angular contact ball bearings can be grease lubrication, oil lubrication is also available. When in use, first consider the grease lubrication, because it is more convenient, but also easy to seal. With lithium soap grease EP additives, such as grease TIMKEN Arcanol L135V, has been proved to be available.
Permissible speed
Bearings with grease lubrication allows speed in the bearing tables, values for O type or X type layout of the bearing on the table in the. Consisting of three or four bearing group allows speed must be reduced.
Friction
For the low friction bearing TIMKEN angular contact ball bearing, thus requiring only driving force is very small.
Equivalent dynamic load
Equivalent dynamic load P through the axial load Fa obtained by the formula:
P = Fa [kN]
The angular contact thrust ball bearing is not suitable for a radial load Fr > 0.47Fa occasions, radial load Fr is very small, it is not considered in the calculation of equivalent dynamic load.
Equivalent dynamic load
In the static working conditions, such as equipment is static, it can bear one-way thrust angular contact ball bearing loads than dynamic load. But the static load is not too big, it will affect the performance of the bearings and plastic deformation, so the static safety factor should not be less than 2.5 fs.
FS = Co? I/Po
Co -- the rated static load [kN]
I -- bear the axial load bearing number
Po -- equivalent static load [kN]
Po = Fa [kN]
Suffix
The TVP entity of window glass fiber reinforced polyamide cage, ball guide
Installation dimension
General information the installation size, bearing table lists the maximum radius of RG and install the shaft shoulder diameter.
