Engineered for the most demanding heavy-duty operations, the 199014340042_1 Air Chamber Bracket represents the pinnacle of braking system integrity. As a core component within Howo/Sitrak truck parts, this bracket delivers uncompromising stability, precision fitment, and enduring performance under extreme pressure. Every HOWO and Sitrak chassis relies on this critical mounting solution to ensure brake chamber alignment and responsive actuation, directly influencing vehicle safety and payload efficiency. The 199014340042_1 bracket is not just a replacement—it is a reliability upgrade.
The 199014340042_1 Air Chamber Bracket is manufactured from high-strength ductile iron (GGG-50) with a tensile strength exceeding 500 MPa. Its geometry precisely matches the mounting footprint of HOWO A7, T7H, and Sitrak C7H chassis, ensuring bolt-hole alignment within ±0.2 mm. This eliminates additional shimming and reduces vibration-induced fatigue.
Each bracket undergoes 100% ultrasonic inspection and magnetic particle testing to guarantee zero internal porosity. The Air Chamber Bracket also features an optimized ribbed back structure that distributes braking torque evenly across the mounting surface, preventing stress concentration. Field data shows a 68% reduction in bracket-related service calls compared to aftermarket alternatives.
For fleet owners, the bracket directly contributes to shorter stopping distances and consistent brake chamber pushrod travel. Its anti-rotation locking design keeps the air chamber perfectly perpendicular to the slack adjuster, eliminating irregular wear on brake linings and drums. This single component can extend brake system life by up to 25%.
All specifications verified under ISO 9001:2015 and IATF 16949.
The bracket is a direct replacement for original equipment. Use new grade 10.9 bolts and torque to 190 N·m in a crisscross pattern. No modification to the frame rail or air chamber is required. The bracket includes integrated alignment dowels that self-center during installation, cutting fitting time by half.
Average install time: 18–22 minutes
Designed for all HOWO and Sitrak trucks equipped with compatible air chambers (type 20/24/30). It has been dyno-tested over 1.2 million braking cycles with zero structural failure. The bracket also fits selected SINOTRUK heavy-duty models with the same mounting pattern.
Verified for: Euro 5, Euro 6, & China VI
Every 199014340042_1 bracket passes 3-stage validation: dimensional CMM, load-to-fracture (min 80 kN), and thermal cycling. The salt spray test exceeds 500 hours, ensuring rust-free performance in coastal or winter-road conditions.
B10 life: 1.5 million km
The Air Chamber Bracket bracket is individually boxed with anti-rust paper and foam inserts. Each carton includes 4 high-strength bolts and washers. Standard export carton: 40 x 30 x 18 cm, suitable for air or sea freight.
24 pcs per pallet (stable stacking)
