For fleet managers and technicians servicing Nissan Diesel mixer trucks, the reliability of every component directly impacts uptime and profitability. The clutch release bearing, a critical link between driver input and driveline engagement, must withstand the punishing stop-start cycles and high-torque demands of concrete transport. Our Release Bearing for Nissan is engineered to meet or exceed the original equipment specifications for Nissan commercial vehicles. It is not a universal part but a precision-manufactured solution designed for perfect fitment, extended service life, and consistent performance, ensuring your Nissan mixer’s clutch operates with the smoothness and reliability the brand is known for.
We specialize in manufacturing heavy-duty driveline components by integrating advanced materials, rigorous quality controls, and a deep understanding of OEM application requirements to deliver parts you can trust.
1. Product Parameter (specification)
Material: Steel
Finish: Powder Coated
OEM No.:31230-E0050
Installation: The installation of the 31230 - E0050 bearing requires certain technical skills and tools. It should be installed by professional technicians in accordance with the vehicle manufacturer's installation instructions to ensure its correct installation position and reliable connection with other clutch components. Otherwise, problems such as clutch slippage and abnormal noise may occur.
Maintenance: Regular inspection of the bearing is necessary. During the vehicle maintenance process, technicians should check whether the bearing has signs of wear, such as abnormal noise, excessive play, or difficulty in clutch operation. If any problems are found, timely maintenance or replacement should be carried out to avoid affecting the normal use of the clutch system and even causing damage to other components of the vehicle.

Why This Matters for Your Nissan Truck |
|
Product Material |
PA66 + 25% GF |
This high-performance engineering polymer is used for the bearing sleeve/carrier. It provides the necessary tensile strength, excellent heat resistance (deflection temp >250°C), and exceptional wear resistance to handle the constant sliding motion against the clutch fork and the thermal loads of the clutch housing. |
|
Manufacturing Process |
GÜNTHER Hot Runner System, 16 Nozzles |
This precision molding technology is essential for producing the polymer carrier with optimal structural integrity. It ensures uniform material density, eliminates weak points, and guarantees the dimensional accuracy required for a perfect, non-binding fit on the Nissan transmission input shaft sleeve. |
|
Primary Application |
Nissan Diesel Commercial Vehicles, including Concrete Mixer Trucks |
This bearing is specifically designed and validated for the clutch systems used in Nissan’s commercial truck lineup. It matches the exact load profile, actuation travel, and physical dimensions of the original Nissan part. |

Product Description |
Precision clutch release (throw-out) bearing assembly for Nissan trucks. We provide full custom manufacturing and mass production based on OEM specifications or customer-provided Nissan part numbers/drawings. |
We deliver a complete, ready-to-install assembly. This ensures the bearing, sleeve, and any integrated seals are pre-aligned and lubricated, guaranteeing correct function from the moment of installation and eliminating variables that cause premature failure. |
Critical Maintenance & Installation Procedures:
The Unbreakable Rule – Do Not Service the Bearing: Modern clutch release bearings are permanently sealed and lubricated at the factory. NEVER wash them in solvent, degreaser, or attempt to re-grease them. Solvent will destroy the internal grease and seals; adding grease will rupture the seals, leading to immediate grease loss and catastrophic failure.
Impeccable Cleanliness During Installation: Handle the new bearing with clean hands. Before installation, thoroughly clean and inspect the transmission input shaft sleeve. Lightly lubricate the sleeve with a thin film of the clutch manufacturer's recommended grease (if specified) to ensure smooth sliding. Any dirt or grit introduced here will act as an abrasive.
The Most Critical Adjustment – Clutch Pedal Free-Play: After installation, you must set the clutch pedal free-play to the exact specification in the Nissan service manual. Insufficient free-play is the #1 cause of premature release bearing failure. It causes the bearing to be in constant light contact with the pressure plate, spinning and generating heat whenever the engine is running, destroying the bearing in short order.
Fleet-Proven Results – A Case Study: A concrete supplier operating a fleet of Nissan CWB series mixer trucks implemented a standardized clutch repair protocol using our bearings. The protocol mandated clutch fork inspection/replacement and precise free-play adjustment. Over 18 months, they tracked a 55% reduction in clutch-related call-backs and unscheduled downtime. The data showed the new bearings, when installed correctly, consistently achieved service lives exceeding 140,000 km in urban delivery cycles, validating the investment in quality components and proper procedures.
Our Manufacturing & Quality Assurance Commitment
Our "large number of high precision machining and inspection equipment" enables us to guarantee the quality of every bearing.
Precision Grinding Technology: We use CNC grinding machines to achieve raceway geometry and surface finishes with tolerances in the micron range (e.g., raceway roughness < Ra 0.25 µm), which is essential for smooth operation, low noise, and long life.
Controlled Assembly Environment: Final assembly is conducted in a clean area to prevent the inclusion of airborne contaminants.
Stringent Final Verification: A statistical sample from every production batch undergoes performance tests, including rotational torque measurement, seal integrity checks, and noise/vibration analysis.
