| Attribute | Description |
|---|---|
| Part Number (OE) | 29Z33-04082 |
| Product Name | Balance Shaft Bushing (also known as Walking Beam Bushing or Balance Axle Sleeve) |
| Common Nickname | "Balance Shaft Copper Sleeve" |
| Application Type | Heavy-Duty Truck Suspension – Tandem Rear Axle System |
| Vehicle Brand | Dongfeng Commercial Vehicle (DFCV), Dongfeng Dana |
| Compatible Models | Dongfeng Kinland (KL), KC Hercules, Kingrun (KR), DF 153 Series |
| Axle Configuration | 6x4, 8x4, 6x2 (with walking beam suspension) |
| Material Type | High-tin leaded bronze alloy (e.g., CuSn8Pb4Zn4) or steel-backed copper-based sintered composite |
| Internal Design | Cross-helical oil grooves for uniform grease distribution |
| Function | Low-friction pivot point allowing vertical swing of balance axle |
| Load Capacity | Supports 10–13 tonne vertical static/dynamic loads |
| Standard Compliance | Meets DFCV OE specifications; conforms to GB/T 18324 (bushings for automotive use) |
| Parameter | Specification |
|---|---|
| Outer Diameter (OD) | Matches bore in balance housing (typically ~φ80–φ90 mm, verify by model) |
| Inner Diameter (ID) | Precision-machined to fit balance shaft journal (clearance: 0.05–0.10 mm) |
| Length | Approx. 70–85 mm (depending on suspension variant) |
| Wall Thickness | 4–6 mm (steel-backed types may vary) |
| Hardness (Surface) | HB 70–90 (bronze); hardened steel backing where applicable |
| Max Operating Pressure | ≥120 MPa |
| PV Value (Pressure × Velocity) | Up to 2.5 MPa·m/s |
| Temperature Range | -40°C to +150°C (short-term peaks up to 180°C due to friction heat) |
| Lubrication Requirement | Re-greaseable via central zerk fitting; requires MoS₂-enhanced grease |
| Design Life (Normal Use) | 80,000 – 150,000 km depending on operating conditions |
