Description
Maximize torque clamping pressure and ensure seamless clutch actuation across your commercial fleet with the genuine ZF Commercial Vehicle Clutch Pressure Plate and Release Bearing Assembly. Engineered specifically for heavy-duty commercial truck gearboxes, manual transmissions, and transit bus powertrains, this OE-grade kit combines a heavy-duty diaphragm pressure plate and a matching self-aligning release bearing into a single complete replacement package. Weakened diaphragm springs, worn release bearing faces, warped pressure plates, or thermal binding cause severe clutch slippage, harsh pedal vibration, incomplete gear disengagement, and premature driveline wear. This original ZF clutch assembly solves those transmission failures directly. It features premium high-tensile alloy steel castings, precision-calibrated diaphragm springs, high-temperature coupling grease, and integrated self-adjusting wear mechanisms to deliver uniform clamping force, ultra-smooth pedal travel, and uncompromised fleet reliability.
Technical Parameters
| Category | Specifications & Technical Details |
| High-Strength Nodular Cast Iron Cover & Plate | We precision-cast the pressure plate body from high-quality nodular cast iron with a high-alloy steel cover plate. It delivers extremely high thermal deformation resistance and burst strength. As a result, it easily withstands the extreme heat load of frequent heavy truck launches and fully loaded hill climbs. |
| Self-Aligning Release Bearing Integration | The ZF release bearing in the kit features slight self-aligning capability. It automatically corrects coaxiality deviation between the input shaft and the pressure plate diaphragm spring. Consequently, it completely eliminates one-sided uneven wear and release noise. |
| Precision-Calibrated Diaphragm Spring | We use a computer-optimized high-rigidity diaphragm spring. It provides constant, powerful clamping force for zero-slip power transmission. Meanwhile, it enables light, rapid release when the pedal is pressed. |
| Automatic Wear Compensation Mechanism | We integrate an advanced automatic clearance adjustment mechanism. It automatically compensates the pressure plate working position as the friction disc wears naturally. Therefore, pedal height and pedal effort stay consistent throughout the entire product service life. |
| Dynamic Balance & High-Temp Sealing | Each unit passes high-precision electronic dynamic balancing before shipment, and we use a high-temperature three-lip sealed bearing. This completely prevents clutch dust intrusion. Notably, it keeps the system running stably and reliably at high speed over the long term. |
Applicable Car Brands & Models
Common warning symptoms include:
Clutch Slippage Under Acceleration: Engine RPM spikes without a proportional increase in vehicle speed when applying full throttle under load.
High-Pitched Chirping or Grinding: Unusual metallic noise or squealing when depressing the clutch pedal, caused by worn release bearing internal races.
Incomplete Clutch Disengagement: Difficulty shifting into first gear or reverse, accompanied by gear crunching due to improper pressure plate lift.
Stiff, Pulsating, or Soft Pedal Feel: Heavy pedal resistance, vibration, or a clutch pedal that fails to return smoothly to its resting position.
Replacing both components simultaneously ensures that the new release bearing face matches the wear pattern of the new pressure plate diaphragm fingers. Mismatched parts cause uneven contact, rapid component wear, premature slipping, and repeat labor teardowns.
Premature failure is typically caused by aggressive driving habits (such as resting feet on the clutch pedal or overloading vehicle weight limits), thermal stress from chronic clutch disc slippage, or oil contamination leaking from engine rear main seals.
Our 1-year warranty covers all diaphragm spring fatigue fracture, housing casting cracks, release bearing raceway spalling, internal seal failure, and non-artificial manufacturing defects under normal operating conditions. If an assembly fails within 12 months, we provide prompt replacement or warranty processing upon inspection.
