EN 2286-1989 pdf download.Aerospace series Bushes, flanged aluminium alloy with self-lubricating liner Dimensions and loads.
This EN 2286 specifies the characteristics of flanged hushes in aluminium alloy with self-lubricating liner and the design recommendation of shafts and housings.
2 Field of application
The bushes are intended for operation within the temperature range of — 55 °C to + 150 °C and assembly with an interference fit into fixed and moving aerospace parts.

6 Marking
In addition to the manufacturer’s own marking each bush and its package shall be marked with the identity block specified in clause 5 of this standard.
Marking position and method are at manufacturer’s option, and shall not have any detrimental effect on the bush.
7 Technical specifIcation
Bushes supplied to this standard shall conform with the requirements of technical specification EN 2311.
The loads given in Table 2 of this standard are only applicable under the conditions given in EN 2311.
8 Design recommendation
Bushes defined by this standard are intended to be installed by interference fit methods (see Figure 2). Therefore, the loads given in Table 2 can only be insured if the following mounting is applied.EN 2286-1989 pdf download.
