## Washdown Gearmotors for Hygienic Industrial Drive Systems
In industrial environments, especially in food processing and packaging automation, gearmotors must withstand aggressive cleaning processes and provide reliable torque under continuous duty conditions. In response to this need, Bison has introduced its 261 Series SanimotorⓇ inline parallel shaft washdown gearmotors.
### Design Features Suitable for Production Environments
The 261 Series SanimotorⓇ was developed for areas exposed to high-pressure and high-temperature cleaning processes, particularly for food and beverage production and applications requiring hygienic automation. The products have an IP69K protection rating, which is the standard for equipment suitable for high-pressure spray cleaning.
The housing, made of 304 stainless steel, is corrosion-resistant and facilitates cleaning. A two-piece, spring-loaded shaft seal and EPDM O-rings are used for liquid sealing. This design maintains sealing integrity through repeated washdown cycles.
To enhance durability, a laser-etched permanent nameplate retains its readability even under harsh cleaning conditions.
### Mechanical Structure and Operating Characteristics
The gearmotors feature integrated 1/7 HP and 1/8 HP AC inverter motors. They can operate in a speed range of 8-350 rpm and produce torque between 1.8 and 56.5 Nm. These values are suitable for hygienic production line motion systems such as conveyors and mixers.
Sealed ball bearings and food-grade H1 grease eliminate maintenance requirements by providing continuous lubrication. This feature offers an advantage in applications where maintenance access is difficult or the risk of contamination is high.
This configuration supports continuous operation in automated production systems and reduced maintenance needs with consistent torque transmission.
