23041147 Bearing Assembly Allison spare parts

The 23041147 bearing assembly is an OE-grade core component specifically developed for the rotating mechanism of Allison heavy-duty automatic transmissions. Manufactured strictly according to original factory drawings and the GB/T 3077-2015 alloy structural steel standard and GB/T 3098.1-2010 bearing industry standard, it has passed ISO 9001 quality certification, wear resistance, impact resistance testing, and sealing performance testing. Balancing load-bearing capacity, rotational stability, and adaptability, it is widely used in Allison 1000/2000 series and 3000/4000 series transmissions in heavy-duty equipment such as heavy trucks, construction machinery, and mining equipment. Its core functions include supporting the planetary carrier, guiding the input and output shaft rotation, and buffering power transmission. Adapting to the high-frequency rotation requirements under heavy-duty conditions, it precisely addresses industry pain points such as bearing jamming, abnormal noise, rolling element wear, cage breakage, and seal failure, extending the overall service life of the transmission, reducing secondary maintenance costs, and ensuring smooth transmission rotation and efficient power transmission, meeting the core needs of efficient operation and maintenance of heavy equipment.

Core technical parameters:

– Product Model: 23041147
– Material specifications: Inner ring/outer ring (GCr15 bearing steel, carburized and quenched, hardness HRC 62~65), rolling elements (GCr15 bearing steel), cage (copper alloy solid cage), seals (double-sided contact rubber seals).
– Operating temperature: -40℃~180℃
– Rotation performance: Rated dynamic load ≥170kN, rated static load ≥240kN, coefficient of friction ≤0.002, smooth rotation without jamming or abnormal noise, dynamically balanced (balance accuracy ≤0.03g·cm).
– Structural parameters: Inner diameter 45mm × Outer diameter 75mm × Length 25mm, Number of rolling elements: 16 (evenly distributed), Sealing cap thickness: 2mm, Tolerance ≤ ±0.02mm
– Wear resistance: The surface is nitrided, the wear-resistant layer thickness is 0.1~0.2mm, and the wear rate is ≤0.001mm/1000 hours.
– Compatible Models/Scenarios: Core compatibility with Allison 1000/2000 series and 3000/4000 series heavy-duty automatic transmissions, widely used in heavy-duty equipment such as heavy trucks, construction machinery, mining equipment, and public transportation. It is compatible with scenarios such as transmission planetary carrier support, input and output shaft rotation guidance, and clutch shaft support. It can directly replace the original factory corresponding bearing assembly, meeting the maintenance needs of transmission overhaul and rotation system replacement, and is suitable for complex working scenarios with heavy load and high-frequency rotation.
– Service life: Under normal heavy-load conditions, the service life can reach more than 18,000 hours, and the continuous operation without failure time is ≥10,000 hours.

The 23041147 bearing assembly, with its precise original factory fit, excellent rotational load-bearing capacity, and long-lasting wear resistance, has become the core preferred component for the repair and overhaul of Allison heavy-duty gearbox rotating mechanisms. We strictly control the production process; each product undergoes dimensional accuracy testing, rotational performance testing, wear resistance testing, impact resistance testing, and sealing performance testing to ensure compliance with original factory standards, GB/T 3077-2015, GB/T 3098.1-2010 standards, and industrial usage requirements. We also provide comprehensive after-sales support and standardized packaging for bulk purchases, resolving various issues customers encounter during procurement and use, and contributing to the reliable maintenance and efficient operation of heavy-duty equipment gearboxes.
