Adaptation size parameters: Wheel diameter coverage of 65mm-120mm (customized according to different vehicle models, such as 75mm wheel diameter commonly used for Ford models and 85mm wheel diameter commonly used for Toyota models); The thickness of the wheel body is 12mm-25mm, which meets the requirements of different belt widths; Installation hole spacing of 30mm-80mm, standard M8-M12 high-strength installation bolts (8.8 grade), suitable for mainstream vehicle bolt specifications.

3. Bearing performance parameters: Adopting double sealed deep groove ball bearings with a tolerance level of P5 (accuracy 0.001mm), radial clearance controlled between 0.005mm-0.012mm, and rotational resistance 30% lower than ordinary bearings; The bearing is filled with high-temperature resistant grease, with a maximum temperature resistance of 180 ℃, ensuring stable operation within the working temperature range of -40 ℃ to 120 ℃.

4. Tension adjustment parameters: Equipped with a spring type automatic tension adjustment mechanism, it can achieve a tension range adjustment of 15N-50N (depending on the vehicle design, such as 20N-35N commonly used for household sedans and 30N-50N commonly used for commercial vehicles), with an adjustment accuracy of ± 5N, effectively avoiding problems such as belt looseness, slipping, or excessive tension and breakage.

5. Extreme performance parameters: The maximum sustained speed can reach 15000 RPM, and the instantaneous peak speed is 18000 RPM, meeting the working conditions of high-speed engines; The designed service life is 150000 km (under normal operating conditions), or an equivalent 5-year service life, far exceeding the industry average service life standard of 100000 km.

6. Certification and quality inspection parameters: Compliant with ISO/TS 16949 automotive industry quality standards, passed SGS material testing and ROHS environmental certification; Each product undergoes three rounds of quality inspection (size testing, tension testing, and speed testing), with a factory defect rate controlled within 0.02%, ensuring quality stability.

Product Uses

Here are specific application scenarios of Tensioning wheel assembly:

1. Daily maintenance scenarios for household sedans: Suitable for mainstream household sedans such as Toyota, Honda, and Volkswagen. When the vehicle travels 80000 to 100000 kilometers and there is abnormal belt noise or idle shaking, replacing the tensioner assembly can solve the problem of belt looseness, ensure normal engine transmission, and avoid the risk of breakdowns caused by belt faults. It is suitable for most 1.5L-2.0L displacement household car models.

2. High frequency operation scenarios for commercial vehicles: For freight/passenger commercial vehicles such as Ford Transit and Iveco, long-term high load operation can accelerate the wear of tensioning wheels. The assembly is resistant to high speeds of 15000RPM and high temperatures of 120 ℃, which can stably maintain belt tension and reduce maintenance frequency. It is suitable for commercial vehicles with 2.5T-3.0T diesel engines and supports daily operation needs of more than 300 kilometers.

3. SUV off-road complex road scenarios: Suitable for off-road SUVs such as Jeep Wrangler, Toyota Prado, etc. In bumpy road conditions such as mountains and mud, the SAE 1045 forged steel wheel body of this assembly has strong impact resistance, which can avoid the displacement of the tension wheel caused by road bumps, ensure the stability of the timing/snake belt system, and is suitable for off-road enthusiasts to use for long-distance crossing.

4. Professional repair scenario in auto repair shops: When the auto repair shop receives repairs for multiple brand car models, the assembly is compatible with 95% of mainstream car models (including American, Japanese, and German), and installation only takes 15 minutes. With detailed adaptation guidelines, it can improve repair efficiency; The 0.02% low defect rate also reduces the probability of repairs, making it a cost-effective replacement option for auto repair shops.

5. Renovation scenario for old vehicles: For vehicles over 5 years old with aging tensioner components (such as the old Audi A6 and Buick LaCrosse), replacing the assembly can restore engine transmission efficiency. Its 150000 kilometer design life can extend the vehicle's service life. At the same time, the aluminum alloy shell is corrosion-resistant and suitable for the engine compartment environment of old car models that are prone to rusting after long-term parking.

Product Operate Guide

1. Preparation before installation: First confirm that the product model is compatible with the vehicle, prepare tools such as wrenches (M8-M12) and torque wrenches, check that there are no debris in the engine compartment, disconnect the vehicle power supply, and wait for the engine to cool down to room temperature before starting operation.

2. Disassemble old parts: Use a wrench to loosen the installation bolts of the old tensioning wheel, remove the old parts, clean the installation position of oil and rust, check whether the belt is worn, and if worn, it is recommended to replace it synchronously.

3. Install new parts: Align the new tensioning wheel with the installation hole, manually pre tighten the bolt, and then use a torque wrench to tighten it to a standard torque of 25-35N · m to ensure that the wheel body is not offset and there is no jamming during rotation.

4. Inspection and testing: After installation, manually rotate the belt to confirm that the tensioner is running smoothly. Start the engine and idle for 5 minutes. If there is no abnormal noise, the installation is complete.
