ISUZU Final Pinion Bearing 1-09812042-1 1098120421 for CVZ CXZ ESZ — 1.3kg OEM Standard
ISUZU Final Pinion Bearing 1-09812042-1 1098120421 Compatible with CVZ CXZ ESZ Heavy-Duty Trucks — 1.3kg Rear Axle Differential Core Component
The ISUZU Final Pinion Bearing with OEM numbers 1-09812042-1 / 1098120421 is a precision-engineered replacement designed for ISUZU CVZ, CXZ, and ESZ series heavy-duty trucks. This component is a core rotating part of the rear axle differential — the Final Pinion Bearing (BEARING; FINAL PINION) — responsible for supporting the pinion gear shaft and ensuring smooth, efficient power transmission from the driveshaft to the drive wheels.
Numbering Note: This product number is 1-09812042-1 / 1098120421. Variants include 1-09812042-0 / 1098120420. Other sources indie this bearing also fits ISUZU NQR71/75, NPR, FSR90 models. Please verify the specific number based on actual vehicle configuration.
Working Principle
The final pinion bearing is a critical support component of the rear axle differential assembly, installed between the differential housing and the pinion gear shaft. Its working principle includes:
Rotational Support: Provides stable rotational support for the pinion gear shaft, ensuring precise axis alignment during high-speed rotation.
Load Bearing: Withstands radial and axial compound loads generated during vehicle operation, including vehicle weight, payload, acceleration/deceleration impacts, and cornering lateral forces.
Friction Reduction: Converts sliding friction to rolling friction through precision rolling elements, significantly reducing energy loss and heat generation.
Gear Mesh Precision: Maintains correct pinion-to-ring gear backlash within specifiion, preventing premature gear wear or noise.
Failure Symptoms
⚠️ Inspect immediately if any of these occur:
Symptom
Probable Cause
Persistent "humming" or "howling" noise from rear axle, varying with speed
Worn bearing; fatigue spalling on rolling elements or raceways
"Clunking" impact noise during acceleration or deceleration
