RTL 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 rigidity
and minimum axial occupied spaces.If the surface of the adjacent parts can be used as 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
the support space is big enough so that a small axial cross sectional altitude can be achieved . Same effectiveness can be ensured in different cases
when combined with the relatively thicker ring gaskets of LS,GS,WS,ZS series.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 |
RTL 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.
RTL thrusting ring gasket MODEL GS,WS,LS are made of bearing steel through quenching.The outer surface of seat ring and the inner surface of blowout
patch are made through grinding while the outer and inner surface of MODEL LS are economically turned.
RTL thrust tray MODEL ZS series are allocated as bidirectional positioning bearings,RTL will provide the ZS middling series,the middling ZS series can be
positioned axially or as per seat holes.

Rel
ated designing |
The bearing 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 ASseries 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 independent gaskets are not used.The bearing capacity and the life will be apparently reduced when the related technical data can
be reached.

Special
requirements |
RTL would recommend our customers to select the standard products.When the standard dimensions can notn be
satisfied,RTL 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 |
