Product Description
Comprehensive Guide to Truck Clutch Release Bearings: Models and Specifications
The clutch release bearing (also known as a throwout bearing) is a critical component in a truck's clutch system. It serves as the pivotal interface between the rotating clutch assembly and the stationary release mechanism. When the clutch pedal is depressed, the bearing transmits the necessary force to disengage the clutch plate from the flywheel, enabling smooth gear shifts.

Key Features and Manufacturing Standards
- Robust Construction: Made from high-carbon chromium steel, hardened and tempered to resist wear and deformation under high stress.
- Sealing Technology: Integrated contact seals (e.g., 2RS) protect the internal rolling elements from contamination by dust, moisture, and debris.
- Heat Treatment: Precision heat treatment ensures consistent hardness and durability in high-temperature environments.
- Precision Grinding: Raceways and rolling elements are ground to ultra-precise tolerances for smooth operation and minimal noise.
Frequently Asked Questions (FAQ)
1. What is the role of a clutch release bearing in a truck?
The clutch release bearing is the interface between the rotating clutch assembly and the stationary release mechanism. It transmits the force from the pedal to disengage the clutch for smooth gear shifting.
2. How do I know if my clutch release bearing is failing?
Common signs include unusual noises when the clutch pedal is depressed, difficulty in shifting gears, and vibrations coming through the clutch pedal.
3. What material is best for heavy-duty bearings?
High-carbon chromium steel (Gcr15) is the industry standard for high-performance bearings due to its excellent wear resistance and hardness after heat treatment.
4. Are these bearings compatible with all Sinotruk models?
While many models like the WG9725160510 are standard for Sinotruk trucks, we always recommend verifying compatibility using your specific VIN or OEM part number.
5. Do your bearings come pre-lubricated?
Yes, our bearings are typically pre-lubricated with high-grade industrial grease designed to withstand high temperatures and heavy axial loads.
6. What is the standard lead time for bulk orders?
For standard models in quantities up to 100,000 sets, the lead time is generally around 5 days. For larger custom orders, the schedule is subject to negotiation.
