BL SERIES<\/strong><\/span><\/p><\/div><\/div>

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 fitted.<\/p>\n

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.<\/p>\n

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.<\/p>\n

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.\"\"<\/p>\n<\/div>
