Thrust needle roller bearings AX,AXWseries

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

Thrust ring gaskets AS,LS,GS,WS,ZSseries

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.

Related designing

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
