Stainless gearboxes for food industry

Baldor has launched a range of all-stainless-steel gearboxes for electric motors, providing machine builders with optimal speed-reducing solutions for clean-area automation such as conveyors. The worm-style gearboxes have several advanced features that include complete sealing, very smooth 316-grade steel exterior surfaces, and a hollow shaft for direct connection to the load. The new Baldor 900 Series of gearboxes provides a single reduction with a choice of 8 ratios from 60 to 5 – providing a 29 to 350RPM output from a standard 1750RPM motor for example. A C-face quill-style input is provided for connection to the motor. Three sizes are available, spanning centre distances from 1.75 to 2.62inches/4.45 to 6.66cm, supporting continuous duty output torques from 160 to 1074in-lbs/18-121Nm depending on the model variant selected from a range of over 50. The gearboxes are constructed using all stainless steel materials, with high-grade 316 used for the exterior casing. This provides a very high resistance to corrosion, for compatibility with caustic cleaning agents, and equips them for use in harsh chemical processing environments. The casing is cast using a special mould to create a standard surface finish of typically ~6.3Ra. This smoothness can be enhanced even further with Baldor’s optional electro-polishing service. Baldor offers a range of compatible stainless steel motors to complement the 900 Series gearboxes.
