English to Spanish Tech/Engineering Mechanics / Mech Engineering Lubricants

There are a few entries in Kudoz, but I am not sure if these apply in this case.
Context:
Intended to lubricate open gears, racks, bushings, rails, rollers, handles, walk mechanisms and low to moderate speed plain rolling element bearings. These applications are subject to extreme contact pressures and reversing loads that may ***dwell*** at zero velocity while loaded.
TIA!
