The Cyclo-Index Basic Drive features a compact, two-piece sealed housing with precision ground shafts, antifriction bearings, and oil bath lubrication. Housings are supplied with oil level and base drain plugs, and with oil fill and vent plugs at the top. Standard housings are provided with mounting holes in side no. 3, but can be supplied in any of the other 5 sides. The housing design allows universal mounting; the units can be operated with the shafts in a horizontal, vertical, or inclined position. Oil level, fill, drain, and vent plug locations must be planned to suit.
