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.

Dimensions: It has a size of 138.5 * 60 * 100 mm, with an inner diameter of 60 mm, a clutch fork width of 100 mm, and an overall height of 138.5 mm.

Maintenance: Regular inspection is required to check for any signs of wear, such as abnormal noise, excessive play, or difficulty in clutch operation. Lubrication should be carried out according to the vehicle manufacturer's recommendations to reduce friction and ensure the smooth movement of the bearing.

Replacement: When the release bearing shows significant signs of wear or damage, it should be replaced promptly. It is essential to use genuine or high - quality aftermarket replacement parts and follow the correct installation procedures to avoid any installation - related issues.

Core Product Specifications & Application Focus

Our manufacturing process is defined by precision and adherence to the exact requirements of the vehicle platform. Every specification for this release bearing is selected to ensure seamless compatibility and performance.

Detailed Technical Parameter Analysis & Key Performance Drivers

1. Bearing Core: Axial Load Capacity & Durability Metrics

Fundamental Parameter – Dynamic Axial Load Rating (Ca): This rating defines the constant axial load the bearing can withstand for a calculated life (e.g., 1 million revolutions). For a Nissan truck application, this rating must accommodate the high clamp force of the heavy-duty clutch. A well-engineered release bearing for this platform typically features a dynamic axial load rating (Ca) between 15 kN and 25 kN, ensuring it can reliably depress the diaphragm spring through thousands of cycles.

Key Influencing Factor – Internal Design & Material Quality: The load capacity is primarily determined by the size, quantity, and geometry of the rolling elements (balls) and the material integrity of the bearing rings. We utilize vacuum-degassed, high-carbon chrome steel (e.g., SAE 52100) for the races and balls, hardened to 58-62 HRC. This specific heat treatment is crucial for achieving the necessary hardness to resist deformation and fatigue (spalling) under repeated high stress.

     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.
