High-strength wear- resistant materials
Housing is HT250 cast iron and flange HT200 cast iron. Gears are 20CrMnTi hardened to 56-62HRC, input & output shafts are 45# steel or 40Cr. Core transmission parts resist impact, abrasion and deformation.
Low temperature rise & quiet operation
Temperature rise ≤25℃ above ambient without load, ≤55℃ above ambient under full load. Running noise is below 65dB. Stable heat generation during long continuous work for quieter production.
Pre-filled oil & 100% pre-shipment leak-proof test
Every unit gets full inspection before delivery, equipped with various standard oil seals or premium SKF seals to eliminate leakage. Pre-filled with PetroChina 320 gear oil, ready to install once received.
High efficiency and energy saving
2-stage reducer efficiency reaches 96%, 3-stage reaches 94%. Minimal power loss cuts electricity cost during long-term operation.
Graded spare parts for versatile working conditions
Bearings and oil seals have standard grade (C&U/Tongli/KSK/CTY/KAK) and imported premium grade (NSK/SKF), suitable for light/heavy load and high/low speed applications.
Anti-rust coating & easy maintenance with safe package
Surface coated with 8480 blue / 7031 grey anti-corrosion paint, packed in plywood wooden cases for transit. Models above R27 are fitted with oil sight glasses to check oil level conveniently.

Q:Is gear oil filled before delivery?
A: Yes, all reducers are pre-filled with PetroChina 320 gear oil at factory. No extra oil filling required, you can install and run directly.
Q:What are the limits of temperature rise and noise under full load?
A:The maximum temperature rise is 55℃ above ambient temperature, and operating noise is controlled under 65dB.
Q: Are all reducers tested before shipment? Will oil leakage occur?
A: Each reducer undergoes 100% full inspection before delivery with high-performance oil seals. No oil seepage or leakage with correct installation and operation.
