  1. Standard gear boxes ie used in all mobile swing and motion control, have lubrication oil internal. So add a 2 ports ( fill and Drain) , make sure housing is sealed, for Baja I would go with a ISO220 gear lube good characteristics at high temp. Key will be gear speeds, very high gear speeds can create oil shear. Note Noria.com is a excellent source for information on all types of lubrication. good basic tutorials as well.
  2. This is a geared electric actuator, with sync stages for extension, meaning all stages move simultaneously. Honestly the key factors for you you seems like the following 1) Collapsed height, 2) Max stroke for final length, 3) connection, this design only really works for a straight vertical RAM lift. 4) Load- what is real initial load and the dynamic load including acceleration, ie dynamics 101. In the end there are tons of excellent actuators on the market, but key on these is speed, mm/sec and load newtons (dynamic). Also environmental conditions: out door, in door, salt spray, IP sealing rating and finally, same load mount issues as a hydraulic cylinder, clevis clevis with spherical rod mounts- Info shown is pretty basic but not applicable to a actual real world move a load application,
  3. Linear actuators using small electric variable motors can get very very low speeds with high speeds. But your issues is beyond speed if you are doing abrasion, then loading is critical so how you are applying the load is as critical as the speed component. Very high loads at very load speeds create issue with variable friction etc. The design layout / structure is as critical as speed. So what is the power component Torque/force is as critical as speed (n). But if you want to achieve very low speeds then review linear bearing assemblies or linear actuators. Thomsen linear actuators is a excellent source for solutions for all environments.
