Model VL2 offers reinforced output-shaft bearings with increased bearing distance. This spread-bearing design accommodates high overhung thrust loads and allows for longer bearing service life. Included with this design is a grease fitting for the lower bearing and a removable plug to allow excess grease to purge from the bearing cavity. The VL3 dry cavity design adds oil-leak protective measures to the VL2 spread-bearing design. The sealing system prevents oil from leaking from the gearbox into the flange. If oil does happen to leak past the seals, it flows down to an oil slinger mounted onto the shaft. As the shaft rotates, the oil will sling off into the dry cavity. A sight tube is provided in order to monitor the dry cavity.
