A Multitude of Washdown Applications
1. NEMA® C flange with quill input accepts 56C, 143-5TC and 182-4TC motor frames. B5 & IEC metric flange options will quill input accepts D56, D63, D71, D80, D90, D100 and D12 motor frames.
2. Vent Free Design. No breather or vents to leak! Factory lubricated for life with premium synthetic Mobil Glygoyle 460 (PAG) lubricant or equivalent suitable for continuous operation within a-10°F to 120°F ambient temperature range. Single-piece aluminum alloy housing is vacuum impregnated with Resinol® RT (MIL-STD 276) for protection and sealing. No secondary finish required but readily accepts paint. Combines light weight with high tensile strength. Precision machined for alignment of bearings and gearing.
3. Alloy steel input shaft and worm shaft. High helix angle worm is case-hardened (Rc 58-60), ground, teeth are profiled and radiused, for noise reduction and enhanced efficiency.
4. Oversized bearings support positively-retained, high speed shaft for higher shock load capacity – ideal for frequent starting and reversing applications. Premium, Nitrile high temperature seals each end.
5. Bronze alloy worm gear is centrifugally cast onto an iron hub for maximum strength, lubricity and superior life.
6. Oversized bearings for radial load capability and maximum hollow output shaft diameters.
7. Hollow output shaft mounting is standard at no extra cost. Reduces total drive envelope size, weight and cost. Solid shaft single and double output is available.
8. Premium, high-temperature Nitrile output seals.
9. Impregnated and machined bearing caps with exterior machined surfaces mate to a variety of mounting accessories. Extra-deep thread engagement provided for greater support strength. Zinc plated hardware. No need to remove bearing covers to mount/change accessory kits.
