The paper examines some fundamental performance and tribological issues of hydraulic reciprocating seals. Topics include the solution of the elastohydrodynamic and contact mechanics problem of polymeric and composite seals, the modelling of seal extrusion and anti-extrusion rings, seal elasticity and its effect on sealing performance, modelling of tandem seals, rotary vane seals, transient effects in lubrication, as well as performance evaluation in terms of leakage, friction, extrusion and wear, followed by optimization.
