Catalog Spurs and Miters
Installation, operation, and maintenance manual.
Nonself-locking mechanical advantage
Spur and miter gears are used in applications requiring a nonself-locking mechanical advantage or where a change in input drive orientation is required. Both devices can be used as add-on features to our worm and bevel gears or can be purchased as stand-alone products.
Unit housings and covers are iron, gears are carbon steel and heat-treated carbon steel, shafts are carbon steel with yellow zinc coating, shaft seals are Buna-N rubber, housing-to cover seals are styrene butadiene, bushings are oil-impregnated copper nickel steel alloy, and bearings are tapered roller and needle type.

† Model numbers that end in A are stand-alone models that are not made to close couple to existing products. These models also have input (handwheel shaft) and output shaft connections. Models that do not end in "A" are designed to close couple to DYNATORQUE 90 quarter-turn worm gear operators. These models have input (handwheel) shaft connections and use the input shaft from the primary operator for their output shaft connections. Models that do not end in "A" are offered as component parts that are assembled to primary operators.
‡ Bolt patterns are offset to match standard spur and miter attachment patterns on faced operators.
