DF361S | Steering axle
DF361S is a F3.6 series high-performance steering axle with an I-beam structure and a rated load of 3600kg.
It is exclusively provided with a dual-specification air brake braking system (φ360×130 or φ400×130, adapted to 19.5° rim).
The optimization of key parameters is remarkable: the wheelbase is adjustable from 2220-2342mm, the rim mounting distance is 1816-1975mm; the center distance of the main pin is 1593-1732mm to enhance the steering stability, and the front axle drop of 100+21mm enhances the passability of the complex road surface.
It is equipped with 7.50×19.5 rims and 245/70R19.5 wide-base tires, the steering angle of inner/outer wheels reaches 40°, and the bolts adopt 8-M20×1.5, which can satisfy the severe demands of heavy-duty transportation.
DF361S Product Features
Heavy Load Upgrade: Flange-forged I-beam technology with load-bearing capacity ranging from 3.6 to 4.5 tons, suitable for heavy-duty scenarios such as mining and engineering.
Efficient Braking: Standard equipped with large Ø430mm air brake calipers, with optional ABS and automatic brake gap adjusters for fast braking response and low heat fade.
Structure Reinforcement: Wider wheelbase (1820-2020mm), reinforced axle housing + tapered roller bearings, enhancing torsional resistance and durability.
Intelligent Maintenance: Supports central lubrication systems (F4.5 series), extending maintenance intervals; optimized sealing of key components reduces failure rates.
