- Total flexibility in mounting options includes shaft, base, face, and flange solutions. The motor terminal box can be mounted in alternative positions rotated in 90° steps around the motor frame providing for unparalleled integration possibilities.
- All position flexibility. The BS unit may be mounted in any required position, i.e. horizontal, vertical, or suspended easily meeting any requirement.
- High level of parts interchangeability for all gearmotor components benefits the customer with increased options, reduced costs, faster deliveries, and a faster maintenance “learning curve”.
- Complying with North American and International standards, including NEMA, IEC, CSA, and CE, the BS series allows for worldwide acceptance, a true total solution for our global customers.
- 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 is a trademark of all Danfoss Bauer geared motors making also the BS series a provider of comfortable and healthy work environments.
- A minimum level of maintenance is a prime feature of the Danfoss Bauer Geared Motor program. Change of lubricant is normally required after 15000 running hrs with mineral oil or after 25000 running hrs or 2 - 3 years with synthetic oil.
