Overhead Conveyor Drives
The NORD SK9055 and SK9155 Conveyor Drive reducers are designed to be a mounting fl ange and output
shaft drop-in for existing Overhead Conveyor Drives. The NORD Conveyor Drives, like our standard industrial
products, offer heavy-duty construction and precisely machined components. By adding a mounting pad, the
standard NORD unit becomes an intelligent drop-in product.
Conveyor drives incorporate the standard NORD VL3 fl ange, which features a spread bearing design with oil safe dry
cavity.
Ratings
NORD uses the standard gearing and housings for these Conveyor Drives.
By doing this, we are able to offer the wide range of ratios, high torque,
overhung and thrust load capacities.
Power Input
Conveyor drives are able to accept different types of power inputs,
including integral or C-face motors and solid input shafts.
For more information see our G1043 catalog.

Spread Bearing Design with
Oil Safe Dry Cavity
The dry cavity design adds additional oil leak protec-
tive measures to the spread bearing design. NORD’s
Quadralip
TM sealing system prevents oil from leaking
from the gearbox into the fl ange. If in any case oil
does leak past the Quadralip
TM seals, it would fl ow
down to the oil slinger mounted onto the shaft. As
the shaft rotates, the oil will sling off into the dry cav-
ity. A sight tube is provided for dry cavity inspection.
At the bottom of the spread bearing fl ange is greased
packed, double lip seal.
