Product Characteristics
HT250 High Quality Cast Iron Housing
The housing is integrally cast from HT250 grey cast iron with high rigidity and excellent vibration damping capacity, which can absorb transmission vibration and suit long-term heavy-duty industrial work.
High-Strength Carburized Precision Gears
Gears are made of 20CrMnTi steel, carburized and quenched to hardness 58-62HRC. Spur gears reach Grade 6 precision, bevel gears Grade 7, featuring outstanding wear and impact resistance.
Complete Reliable Supporting Parts
Transmission shafts are made of quenched & tempered 40Cr alloy steel. Standard bearings are HRB, LYC, ZWZ domestic brands, and SKF imported bearings are available as upgrade option, matched with Taiwan-brand oil seals for long-lasting sealing.
Product advantages
High Transmission Efficiency & Low Energy Consumption
2-stage gearbox efficiency reaches 96%, 3-stage reaches 94%. Less power loss reduces overall electricity consumption during long-time operation.
Low Temperature Rise & Low Noise Operation
Temperature rise ≤40℃ under no load, ≤55℃ under full load, and overall noise ≤65dB. Precision gear meshing minimizes vibration for quieter workshop operation.
100% Pre-shipment Test & Zero Oil Leakage Guarantee
Every unit undergoes full inspection before delivery. Premium Taiwan oil seals are adopted to strictly prevent oil seepage and leakage.
