WORM GEARBOXES > BW SERIES
Aluminium Casing Gearboxes are manufactured with high
quality material in order to guarantee the maximum reliability
and strength for long life of the gearbox. Worm shaft
are made of steel which are case hardened to 58-60 HRC
and profile ground. The thread grinding in the gear
ratios that the module value permits is carried out
with Zl- profile. This improves the contact between
the toothed surface and therefore performance of the
gearbox. This also reduces operating noise of the gearbox.
The worm wheel has a G20 cast iron hub onto which a
casting in AS 1 bronze RIM is fitted.

This series Gearbox are filled with synthetic oil grade ISO VG 320 which is virtually maintenance free and does not require oil change during their lifetime.
