STÖBER has been a pioneer in the gearing industry since 1934. Through
constant innovation, STÖBER today is known for high performance, high
efficiency, and low noise, encompassing various gearing solutions
offered to the industry. STOBER Drives Incorporated, located in
Maysville KY, manufactures products for the North American market.
Beginning with the ComTrac Mechanical Variable Speed Reducer, STÖBER
established itself as a technology innovator, later adding the reliable
constant speed MGS series to broaden the product offering. The MGS
(Modular Gear System) line provides a large range of available sizes,
ratios, mounting flexibility, and extremely responsive delivery options.
STÖBER next introduced ServoFit Precision Planetary Gearheads -
setting the standard for low noise and low backlash in the servo
industry. The SMS (ServoFit Modular System) combines the
proven excellence of the MGS system with servo precision to create a
cost effective alternative in the servo market.
STÖBER has the broadest product offering available, providing one
stop shopping for both the industrial gearing market and the rapidly
growing motion control market.
On behalf of the world wide STÖBER Team, we pledge to meet or exceed
your product and service needs with continued high quality solutions.

efficiency
- Ring gear machined integral to the housing – not welded or pressed
in- provides greater concentricty and more precise alignment
- The output flange dimensions are ISO 9409 and allow easy mounting
to rotary or indexing tables, pinions, timing belt pulleys,
transmission shafting, etc., without using a coupling
- Oversized tapered roller bearings and shafts for high radial load
capacity and superior torsional stiffness
- Single piece steel housing
- Triple-split collet for greater concentricity and low inertia
- TriAdapt® motor shaft adapter system allows installation of motor
in minutes — no special tools required
