Eurodrives BL 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 ZI- 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
This series Gearbox Housing & flanges are made out to
aluminium alloy up to sizes 90 and from size 110 & above
cast iron are used. This series gearbox comes with universal
mounting options in all sizes.
This series Gearbox are filled with synthetic oil grade
ISO VG 320 up to sizes 90 which is virtually maintenance
free and does not require oil change during their lifetime.
From size 110 & above mineral oil is used in general
and synthetic oil on request.
This series gearbox from box 63 & above are mounted
with 2 taper roller bearings on the worm shafts improving
the mechanical resistance to the axial thrust generated
by the worm wheel.
