Sintered bronze and iron bearings

Oil impregnated sintered bearings are maintenance-free and self-lubricating structural elements with high functional reliability and efficiency.

The material is characterised by microscopic pores, filled either with liquid (approx. 30 percent by volume of oil) or solid grease (MOS 2), depending on requirements.


Product characteristics

Main feature of sintered bearings:
high frictional speed and low load.

The bearings - both cylindrical and with a collar - are offered in a large range of dimensions, and they are available ready for installation from our stock.
In addition, we supply solid elements made from sintered or graphite bronze up to a diameter and a length of 80 mm (special dimensions on request) for further processing, as well as silencers made from sintered bronze.
For dimensions and technical information, please see our stock list which will be sent on request.


Production details

The base material for sintered parts such as sliding bearings or other formed parts is iron, bronze and other metal in powder form. This powder is formed under high pressure in dies into components, which are then sintered. In the sintering process, the parts are heated up to a temperature which is just below the melting point. By plastic softening of their surfaces, the material particles fuse together.
The bearings are made according to DIN 1850 part 3. Their availability is detailed in a list. On request, special sizes can be produced.
