Description
Restore effortless gear shifting and eliminate drivetrain vibration across your commercial fleet with the genuine ZF Commercial Vehicle Clutch Release Bearing & Throw-out Bearing. Engineered specifically for heavy-duty commercial truck gearboxes, manual transmissions, and transit bus clutch systems, this OE-grade release bearing transmits pedal release force directly to the pressure plate diaphragm spring under high-speed rotation. Worn contact faces, dried internal grease, or thermal bearing binding cause high-pitched clutch squeal, sticky pedal travel, incomplete gear disengagement, and severe clutch plate burning. This original ZF release bearing solves those transmission failures directly. It combines premium case-hardened alloy steel, self-aligning geometric architecture, high-temperature synthetic coupling grease, and low-friction contact seals to deliver whisper-quiet operation, minimal pedal effort, and uncompromised shifting safety in demanding transport operations.
Technical Parameters
| Category | Specifications & Technical Details |
| Self-Aligning Geometric Design | We build slight self-aligning capability into the bearing rings. It automatically corrects coaxiality deviation between the gearbox input shaft and engine flywheel. As a result, it prevents uneven wear on one side of the release fingers and eliminates severe vibration. |
| High-Purity Case-Hardened Alloy Steel | We manufacture the inner and outer rings and rolling elements from high-purity vacuum-degassed alloy steel. The surface achieves extremely high hardness and wear resistance, while the core retains outstanding toughness to withstand the high-frequency impact of clutch pedal application. |
| High-Temperature Synthetic Coupling Grease | We pre-fill the bearing with long-life specialty synthetic grease. It withstands baking temperatures above 160°C and high-speed centrifugal throw-off. Moreover, it keeps lubrication effective in long-term dry-friction environments. |
| Triple-Lip High-Temperature Contact Seal | We equip high-temperature FKM / NBR sealing rings. They completely block splashed dust and metal particles from clutch plate wear out of the bearing raceways. |
| High-Strength Fatigue-Resistant Cage | We use reinforced engineering plastic or high-strength steel cages. They keep the balls and rollers running smoothly during high-speed rotational release. Notably, this significantly reduces friction resistance and operating noise. |
Applicable Car Brands & Models
Common warning symptoms include:
High-Pitched Chirping or Grinding Noise: A harsh metallic noise that appears or changes volume immediately when depressing the clutch pedal.
Stiff or Vibration-Prone Clutch Pedal: Pulsation or a rough feeling transmitted through the clutch pedal during engagement or disengagement.
Hard Gear Engagement: Difficulty shifting into gear or gear crunching caused by incomplete pressure plate separation.
Clutch Pedal Sticking to Floor: The clutch release mechanism binds, preventing the pedal from returning smoothly after release.
Premature failure is typically caused by “clutch riding” (drivers resting their foot on the pedal while driving), misalignment between the gearbox input shaft and engine, or clutch dust penetrating worn seals and drying out internal grease.
Yes. Fleet technicians strongly recommend replacing the clutch disc, pressure plate, release bearing, and pilot bearing as a complete kit. Since replacing the bearing requires separating the transmission from the engine, replacing all wear components simultaneously prevents redundant labor costs.
Our 1-year warranty covers all raceway spalling, roller/ball fatigue fracture, cage damage, internal seal failures, and non-artificial mechanical defects under normal operating conditions. If a bearing fails within 12 months, we provide prompt replacement or warranty processing upon inspection.
