BM bimetal bushes are composed of two metal strips, in two different materials; the first is normally in steel, the second is normally constituted by an alloy containing copper, which when coupled with the steel strip acts as an internal covering. Furthermore, some sizes also have an external relubrication hole.
The special construction of these bushes means they have good resistance against wear, in particular at medium speed with a medium load, or at low speed with a high load.
SPECIAL TECHINCAL FEATURES
The internal surface of the BM bimetal bushes can include different types of channels, so as to satisfy the various types of applications and lubrication conditions in which the bushes may be used.
The main applications in which BM bimetal bushes are used are the following:
* automotive (motors, motorcycle clutches, frames, chassis, tyre changers, etc…);
* agricultural machinery;
* lifting equipment (hydraulic cranes, platform lifts, etc…);
