Vertically downward output shaft

Vertically downward output shaft

Vertically downward output shaft

(OP)
In general - Is there an oilseal that could cope with a vertically downward output shaft, or do all "designed" boxes have weirs and grease on the lower bearing on this type of unit e.g. mixers, agitators etc?

RE: Vertically downward output shaft

From the Rexnord catalog, Falk RAM Mixer drives

No-leak drywell design physically separates the oil sump from the output shaft to eliminate gear oil contamination of your product.

RE: Vertically downward output shaft

Given proper design and installation, all contact-type oil seals will work fine for a long time in a shaft-down installation ... until they fail.

Weirs, drywells, etc, are the logical evolutionary response to a perceived or real need to avoid contamination of whatever is being mixed even when the oil seals leak.

Need a super-short box?  
Can afford regular preventive maintenance?  
Are really tall when you're sitting on your wallet?
Given that last, nearly anything is possible.
