Key Features
Quadrilip™ Seals
Quadrilip™ seals are standard for most UNICASE™
gear frame sizes. The smaller gear units do not have
dual seals, but the quality of shaft preparation and seal
installation is universal.
The Quadrilip™ system is a sign of quality. The seal
system consists of two sealing lips, a dust lip, and
a grease chamber between the seals. The grease
chamber functions as an additional barrier: it helps
protect the inner seal lip from damage, and helps
prevent external contamination from working its
way in. The grease also lubricates the seal lips and
keeps them soft and fl exible, and prevents them
from wearing quickly by reducing friction between
the seal lip and shaft surface.
All shaft seal surfaces are either roller burnished or
plunge ground, and are an important part of the
seal system. With these processes a smooth surface
fi nish of 12-24 pinch rms can be achieved without
machine lead that causes the seal surface to act as a
pump to force oil out from the reducer or gearmotor.

Modular Design
NORD’s modular design philosophy provides you with
a competitive edge by allowing you to confi gure
drive systems to exactly fi t to your applications. More
than 20,000,000 combinations of totally unique gear-
motors and speed reducers are possible - assembled
in-line or right-angle, mounted by foot or fl ange, fea-
turing solid or hollow shafts with either metric or inch
extensions - to give you complete freedom to specify
a drive solution that’s perfect for you.
Benefi ts
• More output speeds
• More mounting arrangements/Greater fl exibility
• Fewer gear stages/Lower costs
• Metric and inch products
NORD engineers stand ready to assist you with your
custom applications. Most standard drives can be
modifi ed to your purposes, and custom designs can
be developed for special applications.
