In addition to roller bearings, slide bearings are the most commonly used bearings in machines, pumps and similar equipment. Sleeve bearings are used wherever space is limited and where the design demands movement that is stable yet flexible and with as little friction as possible.

Consider when there is direct contact of rotating machine components, wear on the bearing contact surfaces inevitably limits bearing life. A distinction is made between simple plain bearings and hydro-dynamic / hydrostatic bearings - that is to say those with forced lubrication. Attention must be paid to friction, middle bearing pressure, load range (Sommerfeld number), storage temperature, relative bearing play, buckling sensitivity and risk level.

We offer 2 grades:

Massive full ceramic slide bearing made of ZrO2 ceramic concerning DIN 4379 (DIN 1850-1) as a sleeve (plain or with flange). Zirconia ZrO2 ceramic is ideal for components together with steel and has on the basis of its hard surface a good, affordable protection against wear and abrasion.

Massive full ceramic sleeve bearing made of Si3N4 ceramic concerning DIN 4379 (DIN 1850-1) as a friction bearing for guiding wires. Silicon nitride Si3N4 ceramic Si3N4 ceramic takes place through its high mechanical strength and fracture toughness especially for abrasive and high temperature application.
