Products Description
This 81.46122.6112 Steering Shaft Assembly is for SHACMAN heavy-duty truck steering systems. No steering slop, no jamming, no abnormal wear, even in rough terrain, heavy loads, or long-time drives. Built with 40Cr alloy steel, the main shaft has high strength and resists impacts. Forged 20CrMnTi universal joints are wear-resistant and the torque-bearing is ≥3500N·m. Nylon-lined ball bearings have low friction, and they feature self-lubrication self-lubricating. The electrophoretic coating housing is corrosion-proof. Precision-machined spline connections have no backlash, reinforced rubber dust boots are dustproof, waterproof and anti-aging. Crafted by precision forging and heat treatment, it ensures reliable performance from -40℃ to 80℃ engine heat, road vibrations, and mud splashes. Every assembly was tested by steering smoothness, torque transmission efficiency and spline fit tightness.
Features And Advantages
① Precise Steering Control: 40Cr alloy steel shaft and zero-backlash spline connections ensure no lag or drift.
② Durable & Wear-Resistant: Forged universal joints and nylon-lined bearings can reduce friction, the electrophoretic coating can resist rust and heat-treated shaft is not bending easily.
③ Strong Torque Transmission: Reinforced universal joints handle 3500N·m+ torque.
④ All-Weather Reliable: Works in snow, rain, or construction site conditions.
⑤Low Maintenance: Self-lubricating bearings and corrosion-resistant coating mean no frequent greasing, saving time and money.

FAQ
Q1: Fits HOWO T7H?
A1: No, only SHACMAN.
Q2: Steering feels loose after install?
A2: Check if spline connections are fully engaged (no gaps) and mounting brackets are torqued to spec. If still loose, splines may be worn-contact us for replacement.
Q3: Universal joint jams when turning sharply?
A3: Ensure universal joint angle doesn't exceed 30° (adjust mounting position if needed); if jamming persists, the joint may be faulty-contact us for a swap.
Q4: Can it be used for off-road trucks?
A4: Absolutely, reinforced universal joints and corrosion-resistant coating handle rough terrain; nylon-lined bearings resist dust buildup, perfect for off-road use.
