 Diameter R0   10-3 m
 Diameter R1   10-3 m
 Radial gap size h0   10-3 m
 Viscosity hydraulic fluid η    Pas
 Mass m   kg
 Velocity V0   m/s
 Relative eccentricity    -
 Damping length x   10-3 m
 Piston force Fmax   103 N
 Hydrostatic pressure pmax   106 Pa
The damping length is the stroke over which the mass m entering the damper with velocity V0 will come to a halt.

Relative eccentricity is the ratio between the eccentricity of the piston and the radial bearing clearance, for contact ε=1, for concentric piston ε=0
