Industrial motors and gear reducers including the 2000RA worm reducer platform with manufacturer-published dimensional interchange tables.
The Sterling Electric 2000RA worm reducer family has manufacturer-published catalog and dimensional interchange information. This page links to its source catalog and individual model records; matching a listed interchange row does not prove that a unit will fit a particular installation.
These records are not forced into a product family unless the evidence supports that assignment. Verify the complete nameplate and configuration before approving an interchange.
