Model: ZLYJ173 Reduction ratio: 10:1 Output Torque(Nm): 2407 Screw Diameter(mm): 65 Input Power(kw):18.5 Input speed:900 Output speed:90 Allowable output shaft axial thrust(KN):153 ZLYJ Series gear reducer is specially used for plastic and rubber screw fields. 1. It used the highly strength alloy steel gear that should be cementite, quenching and heat 2. It strength of hard tooth surface can reach to HRC54-62.All the gears of reducer need spur technics.So it has high precision and definition. 3. It has high transmission efficiency; 4. It runs placidly and the noisy is low. 5. The volumn is small, the weight is light, the service life is long, the torque is large
