Products Description
The DZ911210015 Release Bearing 430mm Assembly is constructed from GCr15 material, quenched to a hardness of HRC 60-65. This provides exceptional wear resistance and a lifespan 2-3 times that of ordinary bearing steel. The main seal is made of NBR material, with a temperature resistance range of -40°C to +120°C and a lifespan exceeding 8 years of hydraulic oil corrosion resistance. The auxiliary seal is made of PU material with a hardness of 85 Shore A standard, offering enhanced resistance to extrusion deformation and suitable for high-pressure applications exceeding 1.5 MPa. The dust cover is stamped from SUS304 stainless steel, 0.8mm thick, and electrophoretically coated for corrosion resistance. A dedicated degreaser is used in a 40kHz ultrasonic cleaner at a pressure of 0.3 MPa to ensure residual impurity particles ≤5μm on the surface.
Features And Advantages
①Superior Durability: The DZ911210015 Release Bearing 430mm Assembly using GCr15 material combined with a heat-resistant phenolic resin seal ring, reduces wear and extending service life by over 30% compared to standard bearings.
②Efficient Power Control: The pull-type structural design optimizes the force transmission path, minimizing the axial clearance and ensuring precise separation of the clutch friction plate from the flywheel. It eliminates gear shifting jams and improves the smoothness of starting and gear changing.
③Low Maintenance Requirement: Equipped with a pre-filled high-temperature lithium-based grease and a fully sealed structure, it achieves maintenance-free operation within 100,000 km of service, reducing downtime and maintenance costs for truck fleets.
④Low Noise Operation: The optimized internal raceway grinding process and balanced rotating components reduce rotational noise to ≤65 dB, improving the driving comfort of the cab.
Application Scope
The DZ911210015 Release Bearing 430 mm Assembly is mainly used in long-haul logistics trucks that require frequent gear shifting, engineering vehicles operating in heavy-duty and high-temperature environments, or special trucks with high requirements for transmission system reliability.

FAQ
Q1: Can it be used with 420mm clutch systems?
A1: No. The 420mm clutch has a 5mm smaller radial dimension
Q2: What causes abnormal noise during clutch operation?
A2: The reasons may be deteriorated lubricant, seal damage, or excessive axial clearance.
Q3: What installation tolerances must be maintained?
A3: Ensure coaxiality between the bearing and clutch hub and clean the release fork groove to avoid particulate-induced wear.
Q4: How to extend service life?
A4: Avoid "half-clutch" operation, inspect seals quarterly for cracks, and replace lubricant every 2 years.
