Material: Special brass CuZn37Mn3Al2PbSi/So. Pressure angle
15°. Attention: Keyway not according to DIN. The gear wheels
can only be used with worms having the same centre distance and the same
transmission. Can be built into gear systems, no reworking required,
thus short assembly times. * Worm only polished. ** The figures stated
for the efficiency are only reference values, as besides the lead angle,
also mounting, lubrication, speed and assembly have an influence on the
efficiency.
