OVER 9500 ITEMS HELP

YOU GEAR UP FOR

HIGHER PRODUCTIVITY

BROWNING is one of the most comprehensive lines of off-theshelf gears in the industry, including spur, miter and bevel, and

change gears. These are available in 20? pressure angle from 20

to 4 dp, and 14 1/2? pressure angle from 48 to 3 dp ... all designed

to increase output, reduce costs and avoid specials.

? Thousands of shaft-ready finished bore and bushing types (a

BROWNING exclusive) eliminate rework costs, assure truerunning precision at all times.

? More stock sizes made of steel ... you get weldability plus

greater strength, at cast iron prices.

? Extra tooth depth and larger radii provide stronger teeth, a

deeper lubrication reservoir and more clearance.

? Many bevel gears are available hardened for longer life.

? Many odd-tooth sizes.

? Custom gear capabilities - up to 60¡± dia. and 17¡± face.
