Ground Zerol Bevel Gears
Features of Zerol Bevel Gears
Zerol Bevel Gears are spiral Bevel gears with a helix angle of less than 10 degree. Balanced,
and superior performance as they combine the features of straight / spiral bevel gears.
● Allows compact design as no inward thrust force ( ＊ Reference to the figure) is produced,
which causes problems when using spiral Bevel gears.
● Unlike straight Bevel gears, Zerol Bevel Gears can be ground finished, allowing higher
precision, wear-resistance and are quieter, compared with straight Bevel gears.
● Drop in replacement for Bevel Gears can easily be made due to the gears have similar
dimensions for the mounting distance. When replacing, please use a set of zerol Bevel
gears with opposite spiral hands, one right-hand and the other left-hand.
