Product Introduction

In the automotive transmission system, clutch bearings are the core components for achieving power separation and coupling, and their performance directly affects the smoothness of vehicle starting, the stability of gear shifting, and the safety of driving. Our carefully developed clutch bearing series products, with exquisite craftsmanship and innovative design, provide efficient and reliable transmission support for various vehicle models, helping vehicles maintain excellent performance under complex working conditions. ​

1、 Core structure and working principle

Clutch bearings are mainly composed of inner and outer rings, rolling elements (rollers or steel balls), retainers, and sealing structures, and usually work in conjunction with clutch release forks. When the driver steps on the clutch pedal, the bearing moves axially under the push of the shift fork, compressing the clutch pressure plate and separating the lever, interrupting the power transmission between the engine and the transmission, and achieving gear shifting operation; After releasing the pedal, the bearings reset and the power is reconnected. This structural design ensures precise switching of power transmission and serves as the "power switch" for the clutch system. ​

2、 Excellent performance advantage

1. Low friction, high response, smoother shifting

By using high-precision rolling elements and optimized raceway design, combined with low friction coefficient lubricating grease, the friction resistance during bearing operation is significantly reduced. Even in high-frequency gear shifting scenarios (such as urban congested road conditions), it can still maintain sensitive response speed, reduce gear shifting shock, make the starting and shifting process smoother, and improve driving comfort. ​

2. High load-bearing and wear-resistant, with a longer service life

The inner and outer rings of the bearing are made of high-strength bearing steel (such as GCr15SiMn), which has undergone processes such as overall quenching and precision grinding. The hardness can reach HRC60-65, and it has excellent compressive strength and wear resistance. The surface of the rolling element has undergone ultra precision machining to reduce contact stress concentration, and can withstand the axial thrust of the clutch pressure plate for a long time (up to thousands of newtons), maintaining stable performance throughout the entire life cycle of the vehicle and reducing replacement frequency. ​

3. Comprehensive sealing protection, suitable for complex environments

Equipped with a dual lip rubber seal and dust cover combination structure, the sealing lip is made of oil resistant and temperature resistant nitrile rubber material, which can effectively block impurities such as dust, oil, mud and water from entering the bearing interior, while preventing grease leakage. Even in high temperatures (engine compartment temperature can reach over 120 ℃), humid or dusty environments, internal cleanliness and lubrication effectiveness can still be maintained, extending maintenance cycles. ​

3、 Wide adaptation and scene advantages

This series of clutch bearings, through modular design, can be adapted to micro cars, sedans SUV、 Various vehicle models such as pickup trucks, light trucks, and medium to heavy-duty trucks meet the matching requirements of engines with different displacements (1.0L-12L) and clutch systems. Whether it is a family sedan for urban commuting, a commercial vehicle for long-distance transportation, or a construction vehicle that frequently starts and stops, it can be precisely adapted to play the following scene advantages:

Urban driving: The low friction characteristics under high-frequency shifting reduce power loss and improve fuel economy; ​

Heavy load transportation: High load-bearing capacity ensures stable power transmission during climbing and starting, avoiding slipping or failure; ​

Adverse road conditions: Strengthen the sealing structure to resist sediment invasion and adapt to complex environments such as rural dirt roads and mining areas.
