Sliding bearing

INDUSTRY

MATERIAL

APPLICATION

Ceramic sliding bearings are very useful under corrosive conditions or in fluids that contain sand or other abrasive particles. After all, ceramics are much harder than sand and excellent resistant to practically every environment. Ceramic sliding bearings are applied in several liquid pumps (submersible, impeller, screw, plunger, gear and magnetic coupled pumps), mixers, as radial or radial-axial bearings, single or double.

The pumped liquid, such as water, takes care of lubrication.

CHARACTERISTICS

from -40 ˚C to 350 ˚C
high rpm's and loads
medium-lubricated
wear and corrosion resistant
metal/ceramic system (cartridge)
compact construction

easy to build-in
longer maintenance intervals
low weight
non-magnetic
electric insulating

ADDED VALUE

Ceramics will have an added value if:

Hard particles are involved in or around the pump, or medium pumped.
Pumped medium is used for lubrication of the bearing. (water, ethanol even H2SO4)
Liquids are corrosive, abrasive or have extreme temperatures or a very low viscosity.
Common bearing materials fail.

STANDARD FORMATS

Maximum use temperature for these bearings is 150 degrees Celsius.

Optimum condition for these bearings are 3600 rpm for the 20MB89, and 1200 rpm for the 100MB1516, temperatures under 100 degrees Celsius, no misalignment, gentle start up, balanced rotation of the radial load.
