When I was in college (eons ago) I worked in a factory that manufactured hydraulic cylinders. I ran grinders for the shafts, dipped them in the chrome vats, and polished the shafts after chroming. I can tell you that chrome is amazingly porous, and is quite susceptible to rust forming beneath the thin chrome veneer. I suspect that any problems with the jacks retracting may be due to a rough surface from slight corrosion forming. This can be removed with very fine steel wool, then apply a protective coating.
If you are going to have the jacks extended for any length of time, it would be advisable to coat them with something for corrosion protection. WD-40, other forms of silicone, ATF, motor oil, anything to coat the surface and prevent corrosion will eliminate problems. This is especially important in any humid or other environment that has a high corrosion potential. The molecular film of oil on the smooth surface after extending the jacks will last for a period of time, but eventually will need something to extend that protection.
