Corporation was started in March, 1941 as a spin-off of the
Brother Corporation. Nissei’s original role was as a
manufacturer of precision machined components for Brother sewing
machines. Nissei Corporation evolved by the mid-1950’s to become
one of the largest manufacturers in the world of fine-pitch gears.
By the mid-1960’s Nissei had grown again to encompass the
manufacturing of die castings. These technologies and know-how
were subsequently combined in the production of a broad range of
gearmotors. Today, Nissei Corporation is comprised of the Gear
Products Division, producing two million gears
per month and the Transmission Equipment Division, producing gearmotors
and gear reducers.
Corporation of America was established in 1995 to provide direct
sales and application engineering support to customers who had
previously known Nissei only through a trading company. Nissei
Corporation of America also provides a warehouse service and
supply chain management based on customer periodic forecasts.
production capacity and tooling inventory allows Nissei to respond
quickly with prototype parts, typically within six weeks ready to
ship from order placement. Full documentation, as requested by our
customers, is provided with each shipment. Such documentation may
include GR&R studies, Cpk data, Full Piece Inspection reports
and heat treatment reports.
metrology equipment provides the means to control quality, to
document quality and to troubleshoot. Nissei’s Gleason No. 554
Single Flank Roll Tester, one of a small number in the world, is
equipped with rotary encoders and a computer analysis package.
Rolling quality can be observed and its’ characteristics
measured and compared independently in “forward” and “reverse”
operation. The parts operate with backlash at the housing mounting
locations, duplicating closely the actual assembly conditions. The
rotary encoders determine how accurately the gearset delivers
uniform angular motion transmission. The errors are treated
mathematically by the computer to determine the frequency and
magnitude of the associated velocities and accelerations, of
interest for noise and vibration quality.
Thank you for
taking time to consider us. We look forward to an opportunity to
serve you. If you would like to request immediate follow up,

**Nissei is one of few manufacturers in the
world who has developed manufacturing and application know-how for
High Ratio Hypoid (HRH) gearing. The HRH is a modified hypoid that
can be used in ratio's up to 1:360. Nissei uses the HRH in their
gear motor products and has manufactured the HRH for OEM
applications in hand power tools and automotive steering systems.
The HRH is a more compact and more efficient alternative to the worm gear.
