This heavy-duty rear wheel hub for Howo trucks handles the toughest road conditions. We manufacture it using high-strength forged steel that stands up to serious impact and continuous heavy loads. The hub goes through controlled heat treatment to enhance surface hardness and wear resistance. What makes this hub reliable is its precision-machined bearing seat, specifically designed to match Bearing 32222 perfectly. This precise fit eliminates any play, ensures smooth rotation, and prevents premature wear. The design also promotes better heat dissipation during long hauls. As a direct OEM replacement, installation is straightforward - it fits right into your existing axle assembly.

- Compatibility: Direct fit for Howo T-series trucks
- Design Feature: Optimized ventilation ribs for better heat dissipation
advantages
- Built to Handle Heavy Loads：we use SAE 1045 carbon steel and forge it under high pressure, then normalize the entire hub to relieve internal stresses. This gives you a component that consistently handles the 6.5-ton load rating without warping or cracking.
- Precision Fit for Longer Bearing Life：our CNC turning process guarantees the bearing seat maintains exact concentricity. This means Bearing 32222 sits perfectly square and tight, eliminating those slight wobbles that typically cause premature bearing wear.
- Keeps Contaminants Out, Grease In：the dual lip seal design uses spring-loaded nitrile rubber. In real-world use, this effectively blocks dust and water from entering while keeping the lubricant sealed inside. Most users see normal service intervals extend reliably to 50,000 km.
- Runs Cooler Under Load：the added rib pattern isn't just for strength - it increases surface area significantly to dissipate heat more efficiently. Testing shows this design helps maintain lower bearing temperatures, especially during prolonged braking or mountain routes.
Compatible Models
- Fits Howo T5G, T7H series trucks. Also works with Howo A7, ZZ3257, ZZ1257 and similar truck models.
