Tol-O-Matic SlideRite CR (corrosion resistant) gearboxes target packaging equipment with washdown requirements or operating environments where water or high relative humidity is present. The units consist of two 45-degree helical gears that mesh at right angles and achieve shaft speeds up to 1,200 rpm. The gearbox has corrosion-resistant electroless nickel-plated geared sleeves, keys and retaining rings as well as corrosion-resistant stainless steel bearings and races. A one-piece hard-coated aluminum case provides a built-in lubricant reservoir. The factory-lubricated units are leak-proof with floating operation in either direction on keyed shafts for long-term alignment. Operating temperature range is 0 to 300F. Recommended shaft materials are either alloy steel or stainless-steel for shafting with a minimum hardness of RC40 or transmission shafting grade such as 4140 or equivalent.
