What I mean is your Amazon link for the 5-1310x has two styles (like how Amazon lists different colors or sizes of product). One is non greaseable, the other is greaseable.The sealed/non-greasable version, the 5-1310x
Looking closer I see that the greaseable one is a Spicer 5-1310-1X. Its zerk fitting is in the middle of one of the end caps so it doesn't look like it's taking away strength versus the 5-1310X (it isn't creating any stress risers in critical places).
I'm assuming your advice still applies—greaseable isn't really needed for most cases? Do you think this greaseable version will require more frequent maintenance than the non greaseable version under the same circumstances? I like having the option of adding grease but not if it costs longevity when I forget to grease it.
Edit: I forgot that oil passages have to be drilled for the greaseable one. So it's not just a zerk fitting taking away strength.
Edit 2: I think I'm answering my own questions. A reviewer on Amazon said this about the greaseable vs non greaseable 1310: "They must be greased at regular intervals and do not have very good seals. If you don't grease them on time, they will fail pretty quickly. The permanently greased ones don't require this kind of maintenance and have double seals."
So it sounds like non greaseable is the way to go for me! And if I happen to begin fording rivers then I'll rethink it at that time.
Thanks!
