Thrust-cylindrical roller bearings 811,812 series |
|
|
|
|
|
Thrust needle and retainer assembly are composed of a set of tray ring gaskets combined with retainer with roll bearings |
(needles). The stand leads and holds many rolling elements ( only very tiny differences among the elements in the same |
group ). The thrust needle bearings or Thrust-cylindrical roller bearings can support the bearings with the axial directional |
load and so they can be used as the bearings with good rigidityand minimum axial occupied spaces.If the surface of the |
adjacentparts can be usedas a tray for the rolling needles and the holding stand assembly , configuration of bearings |
can be very compacted . In case this disposition can not be realized ,As series tray assembly should be recommended |
when thesupport space isbig enough so that a small axial cross sectional altitude can be achieved . Same effectiven- |
ess can beensured in different cases when combined with the relatively thicker ring gaskets ofLS,GS,WS,ZSseries. |
The applicable gaskets series of AS,LS,GS,WS,ZS are optional and will be ordered sparately by the buyers |

1mm thick thrust ring gasket MODEL AS is made of quality spring steel through pressing,it will be most suitable for the |
surface of the adjacent part when it is not rigid enough for trays. |
|
|
|
|
Thrusting ring gasket MODEL GS, WS, LS are made of bearing steel through quenching . The outer surface of seat ring |
andthe inner surfaceofblowout patch are made throughgrinding while the outer and inner surface of MODEL LS are |
economically turned. |
|
|
|
|
|
|
|
Thrust tray MODEL ZS series are allocated as bidirectional positioning bearings, we will provide the ZS middling series, |
the middling ZS series can be positioned axially or as per seat holes. |

Thebearing case and its axial support must keep straight to the rotary axis , the support of the bearing gaskets in the |
wholle tray must be reliable.The sizes of Ea,Eb must be verified carefullu when AS series gaskets are used so that the |
gaskets are fully support.The hardness of the related trays should be HRC58-64 and the roughness Ra0.4um when ind- |
ependent gasketsare not used.The bearing capacity and the life will be apparently reduced when the related technical |
data can be reached. |

Special requirements |
|
|
|
|
|
|
|
SLS would recommend our customers to select the standard products.When the standard dimensions can not be sati- |
sfied,we can also accept orders with special dimensions from the customers if the orders are economically reasonable |
At the same time we would supply our products with BS standards |
