Features and Benefits

Total flexibility in mounting options allow unparalleled integration possibilities.

High level of parts interchangeability for all gear motor components benefits the customer with increased options, reduced costs, faster deliveries, and a faster maintenance “learning curve”.

Generously dimensioned ball or roller bearings, case hardened forged and ground gears, and internally and externally reinforced gearboxes ensure a long, low maintenance service life.

A hardened wear sleeve and spray ring at the rotor seal allow for reduced sump capacity, reliable lubrication and many years of leak free performance.

Quiet running and high efficiency are trademarks of all Bauer geared motors.

A minimum level of maintenance is a prime feature of the Bauer Gear Motor program. Change of lubricant is normally required only after 15,000 operating hours.

Superior protection of IP65 acc. to IEC 529 assures you that the all geared motors are dust tight and hose proof, and can be used outdoors or in wet and dusty environments without the use of additional enclosures. Full rated output is available at the output shaft of the unit.
