High-precision microgeometry – The Shacman WP10 Main Bearing Group features a refined surface finish Ra ≤0.25μm, ensuring rapid oil film formation during cold starts and reducing boundary friction dramatically.
Thermal stability – With a tri-layer structure (steel back + nickel barrier + AlSn20Cu lining), the WP10 Main Bearing Group withstands intermittent temperatures up to 180°C without galling or loss of clearance.
Optimized lubrication grooves – Each main bearing shell in the Shacman WP10 Main Bearing Group has strategically positioned oil slots to maximize flow to connecting rod bearings, even at low idle speeds.
Load capacity validation – Dynamometer tested under full load cycles simulating 1.2 million km, the WP10 Main Bearing Group exhibits no fatigue cracks, proving durability for on/off highway applications.
The Shacman WP10 Main Bearing Group utilizes continuous cast copper-lead alloy with a 0.02mm electroplated overplate. This composition resists corrosion from acidic oil degradation and offers exceptional conformability for misalignment compensation.
Laser-micrometer inspection ensures the WP10 Main Bearing Group maintains wall thickness tolerance of +0/-0.005mm. Each shell is individually coded for traceability, supporting zero-defect production philosophy.
Proprietary heat treatment relieves residual stresses in the steel backing, preventing dimensional creep. The Shacman WP10 Main Bearing Group delivers consistent crush height, eliminating bearing spin in high-vibration WP10 engines.
All WP10 Main Bearing Group components are RoHS compliant and lead-free where regulations apply. Eco-friendly manufacturing combined with premium performance ensures sustainable heavy-duty operation.
This Shacman WP10 Main Bearing Group directly replaces OEM part numbers 611600010019 and 611600010020, matching original equipment specifications for Shacman F3000, X3000, and Delong series trucks powered by WP10.270, WP10.290, WP10.336 engines.
The bearing width and radius perfectly align with WP10 cylinder block main bearing bores. Our WP10 Main Bearing Group fits both standard and remanufactured crankshafts without additional machining, reducing downtime during engine overhaul.
Backward compatibility includes Euro II, Euro III, and Euro IV emission versions. When you select the Shacman WP10 Main Bearing Group, you secure genuine interchangeability with Hino, Cummins-derived blocks (only Shacman WP10 architecture).
Installation notes: Always pair the WP10 Main Bearing Group with new connecting rod bolts and proper assembly lube. The upper and lower shells are not interchangeable – follow marked positions for optimum clearance.
Before installing Shacman WP10 Main Bearing Group, thoroughly clean bearing housing and cap surfaces using lint-free cloth. Check for burrs or dirt that could cause high spots. Oil the back of the shell lightly – do not use grease on the steel back.
Apply engine assembly oil to the bearing inner surface. When torquing main cap bolts, follow WP10 service manual sequence: first 80 Nm, then angle tighten +90°. The Shacman WP10 Main Bearing Group requires final torque of 180 Nm + 15° for M12 bolts.
After installing the WP10 Main Bearing Group, rotate crankshaft manually to verify smooth movement without binding. Plastigage check should reveal oil clearance between 0.048mm and 0.082mm. Replace if out of spec.
Always use new main bearing bolts to maintain consistent clamping force. The Shacman WP10 Main Bearing Group will achieve maximum performance after 500 km break-in period with frequent oil changes at initial 1000 km interval.
Fatigue limit test: Shacman WP10 Main Bearing Group sustains dynamic load of 92 MPa without spalling, exceeding industry standard (SAE J506) by 22%. This translates to reliable operation at 2100 rpm and 1400 Nm torque output.
Scuffing resistance: under boundary lubrication (oil starvation), Shacman WP10 Main Bearing Group withstands 3 minutes at 2500 rpm before temperature alarm, providing safety margin during low oil pressure events.
Corrosion testing after 500h salt spray reveals zero pitting on Shacman WP10 Main Bearing Group’s flash layer, suitable for coastal or chemical plant operations where moisture intrusion may occur.
Wear depth after 800 hour full-load engine dyno cycle measures only 0.004mm for upper shell and 0.0035mm for lower shell, proving exceptional durability of Shacman WP10 Main Bearing Group under continuous heavy duty.
Q: Can I mix Shacman WP10 Main Bearing Group upper shell with another brand lower shell? A: Not recommended. The matched pair ensures correct crush height and oil clearance. Always replace both shells with original WP10 Main Bearing Group components.
Q: What is the shelf life of WP10 Main Bearing Group? A: When stored in original packaging at room temperature (humidity <60%), the bearing remains usable for 5 years. Anti-corrosion oil prevents oxidation.
Q: Does the Shacman WP10 Main Bearing Group fit WP10.350E50 engine? A: Yes, 100% compatible. The same bearing set serves all WP10 series including WP10.350, WP10.375, and WP10.400 variants (except WP10H which requires different width).
Q: How to verify genuine WP10 Main Bearing Group? A: Look for laser etched part number, chamfered oil hole edges, and uniform metallic luster. Counterfeit bearings often lack the characteristic matte finish.
Reduced friction from the Shacman WP10 Main Bearing Group directly lowers CO₂ emissions by approximately 1.2 g/kWh. For a fleet of 50 trucks, annual carbon reduction equals 12 metric tons, supporting green logistics.
The advanced polymer coating on the WP10 Main Bearing Group eliminates break-in metal debris, minimizing contamination in engine oil and extending DPF life. Cleaner combustion, fewer oil changes.
Shacman WP10 Main Bearing Group is 100% recyclable at end-of-life. Steel back and copper alloy are recovered in closed-loop process, aligning with circular economy principles for heavy-duty parts.
Field data from 800 Shacman trucks shows 15% longer bearing life compared to aftermarket generic brands. The Shacman WP10 Main Bearing Group reduces total cost of ownership and unplanned downtime.
Every Shacman WP10 Main Bearing Group is subjected to non-destructive eddy current testing to detect micro-cracks in the steel backing. No batch leaves factory without passing Cpk >1.33 process capability index.
Random samples from each production lot go to ISO 17025 accredited lab for metallographic analysis. The Shacman WP10 Main Bearing Group meets or exceeds DIN 1497 and SAE 780 specifications.
