right angle gearbox 4:1 ratio is used to transmit rotary motion, mechanical power and torque from input shaft to output shaft by 90 degree angle assembly spiral bevel gear set. Transmission efficiency up to 98%. Transmission gear ratio 1:1, 1.5:1, 2:1, 2.5:1, 3:1, 4:1 and 5:1. 42 types shaft arrangements and direction of shaft rotating, 6 types mounting positions. Solid shaft and hollow shaft with 2 way, 3 way, 4 way are available. Allowable revolustions from 10Rpm to 1450 Rpm, power rating from 0.01Kw to 335Kw, work torque from 11.6N.m to 5713N.m. Compared to worm gear reducer, right angle gearbox 4:1 ratio is of low transmission gear ratio, low backlash arc, quiet running, high transmission efficiency and high torque.

right angle gearbox 4:1 ratio is equivalent to Taiwan HUANG YIH HLG bevel gearbox, LI-MING TH bevel gearbox, YONGKUN TNT bevel gearbox, PEEI GM bevel gearbox, Longgoung LG bevel gearbox, Korea SAMYANG SMB bevel gearbox, Japan TSUBAKI ED bevel gearbox and NISSEI COMPASS KNB or KNC bevel gearbox.
