Composite bushings are dry sliding (journal) plain bearings intended for radially loaded bearing arrangements and require a minimum of radial space. They permit oscillating or rotational movement. They are appropriate for all applications where freedom from maintenance is required or where lubricant starvation can occur.
Composite bushings are available as standard in two designs which differ in the composition of the sliding layer: Composite B/E (fig 1) and Composite M (fig 2) bushings. The composition of the sliding surfaces is described in detail under "Composite dry sliding bearing materials".
I wonder how good they are... Any idea's?
And if you would oil them would they be better?
Thanks
