NORD: Reliable mixing with heavy-duty spread bearing design

NORD offers several variations of the VL-duty spread bearing designs, all which have specific features and advantages based on the specific mixing and agitating application requirements.

VL2 offers reinforced output shaft bearings with increased bearing distance. This spread bearing design accommodates for high overhung thrust loads and allows for longer bearing service life.

The VL3 dry cavity design adds additional oil leak protective measures to the VL2 spread bearing design. NORD’s Quadralip sealing system prevents oil from leaking from the gearbox into the VL2 flange. If oil does happen to leak past the QuadralipTM 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.

VL4 is a heavy-duty drop bearing design with a drywell. While most drywell designs simply have a small oil dam tube inside the gear unit, NORD’s stationary oil dam tube extends vertically above the top of the gear unit housing. This provides a much higher degree of leak safety. Additionally there is a sealing o-ring at the top of the oil dam for maximum protection.
