The Morse corrosion-resistant, all-stainless-steel Raider worm gear reducer comes with C-face input, solid and hollow output, as well as stainless steel accessories. Features include 316 stainless steel housing, which offers greater corrosion resistance than 304 to pitting that can be caused by some washdown solutions, non-metallic quill liner on C-face input, dual encapsulated seals, and food-grade oil for USDA/FDA compliance. Emerson offers paint-free stainless motors to provide a gear and motor package from one source. Since its introduction in 2003, this product line has been providing application solutions where corrosion cannot be tolerated.

In one case, the worm gear boxes are used by House of Raeford in Raeford, N.C., a poultry-processing plant. Maintenance manager at the plant, Don Gruver, states, “We go through a lot of gearboxes. Our conditions are tough and will corrode a normal gearbox quickly. We have battled rust and flaking paint here for years on traditional drives.

“While working with Emerson Power Transmission we discovered their new stainless steel Raider worm gear boxes. After trying these units for only a short period of time, we were hooked. The stainless steel finish is smooth and does not harbour bacteria. We have no problems with corrosion since the switch and the non-metallic motor quill liner makes the motor removal effortless. I am currently in the process of switching all of my traditional worm gear drives to the stainless steel Raider.”
