Hydrodynamic radial journal bearings

Calculation in accordance with Niemann
Calculation of power loss, oil throughput, oil warming, minimum lubricating gap size in accordance with G.Niemann. Calculation for pressure lubrication bearings (circulating oil lubrication) with test for operating safety.
Calculation according to ISO 7902
Calculation provides good, detailed method for calculating stationary, hydrodynamic plain radial bearings that are to run at low and average speed.



Hydrodynamic axial journal bearings

Calculation in accordance with DIN 31653

Complete calculation of axial bearing accordance with DIN 31653, part 1 to 3 for pressureless lubrication & pressure lubrication bearings. All operating data as stipulated in DIN 31653, such as operating temperatures, minimum lubrication gap width, power loss, oil throughput, etc are calculated.


Calculation in accordance with DIN 31654

Complete calculation of axial bearings in accordance with DIN 31654, part 1 to 3 for pressureless lubrication and pressure lubrication bearings. The type of lubricating feed (lubricating holes, lubricating grooves, lubricating pockets) is taken into account. All operating data stipulated in DIN 31654, such as operating temperature, minimum lubrication gap width, power loss, oil throughput , etc is calculated. Sample calculation output is attached for your reference.
