Base material
Johnson Metall AB produce a wide range of copperbased alloys, four of which are used as base material in OILES 500 bearings. Data relating to those alloys is given in the table below. The capacity of carrying load is very much dependent on the choice of alloy. The selection of the base material will thus be based on the requirement of load carrying capacity. Note that the temperature has an influence on the allowable load values and also the choice of lubricant.| Base Material | JM1-15 Cu85 Sn5 Pb5 Zn5 |
JM3-15 Cu88 Sn12 |
JM5-15 Cu80 Sn10 Pb10 |
JM7-15 Cu82 Ni4 A110 Fe4 |
