23048007 bearing Allison spare parts

The Allison 23048007 bearing, as a core rotating support component of the Allison transmission shaft system, is hailed as the “smooth foundation” of transmission operation. Its core function is to provide precise support and reduce friction for key rotating components such as transmission shafts and gears, reduce the frictional resistance of components, absorb operating vibrations, ensure smooth rotation of the shaft system, and prevent failures such as shaft deformation, gear damage, and poor power transmission caused by bearing wear, jamming, and abnormal noise. This ensures efficient and stable power transmission of the transmission, extends the service life of the entire machine, and reduces maintenance costs and downtime losses.

Core technical parameters:

-Part Number: Allison 23048007
– Material Specifications: Made of high-quality high-carbon chromium bearing steel (GCr15), balancing hardness and toughness, processed through a professional heat treatment process of quenching, tempering, and precision grinding, strictly following the heat treatment technical conditions of GB/T 34891-2017. Tensile strength ≥1500MPa, Rockwell hardness controlled at HRC60-64, high material purity, strict control of impurity content, significantly improving wear resistance, impact resistance, and fatigue resistance, suitable for the high-frequency rotation and heavy-load conditions of gearbox shaft systems; the inner and outer rings and rolling elements of the bearing are precision ground and polished, with a roughness of Ra≤0.1μm, reducing operating friction and improving quietness.
– Structure type: Deep groove ball bearing (specifically for gearbox shaft systems), featuring an integrated sealing structure and equipped with high-quality nitrile rubber (NBR) seals, providing triple protection against dust, oil, and water, meeting the requirements of GB/T 32321-2015 “Test Procedure for Dustproof, Grease Leakage and Temperature Rise Performance of Deep Groove Ball Bearings with Rolling Bearing Seals”; the rolling elements adopt a precision ball design, undergoing rigorous sorting to ensure high dimensional consistency, and are combined with a stamped steel cage to effectively guide the rolling elements to run smoothly, reducing friction and vibration, and lowering operating noise (noise ≤55dB); the inner and outer rings of the bearing feature a chamfered design for easy installation, preventing scratches on the shaft system and mounting groove during installation, ensuring smooth and unobstructed installation.
– Dimensions: Inner diameter φ30-60mm, outer diameter φ62-130mm, width 16-30mm, chamfer size 1.5-2.5mm, dimensional tolerance controlled within GB/T 307.1-2017 P6 grade precision, precisely matching the Allison gearbox shaft system dimensions and mounting groove specifications, with the fit clearance controlled within 0.005-0.015mm. After installation, the shaft system can be precisely positioned, fully adapting to the original factory installation size requirements, and the error meets the industry precision bearing standards.
– Performance Indicators: Temperature resistance range -40℃ to 180℃, adaptable to the high temperature and high pressure environment inside the gearbox; after high and low temperature cycle testing, no cracks were generated and dimensional changes met specifications after multiple cycles; oil resistance grade meets GB/T 1226-2010 standard, resistant to corrosion from various gearbox oils and hydraulic oils; excellent sealing performance of the sealing ring, effectively preventing dust, oil, and impurities from entering the bearing and avoiding wear; impact resistance meets ISO 16750 standard; fatigue life ≥1000 hours, meeting the requirements of GB/T 24611 “Test Method and Performance of Bearing Fatigue Life”, capable of withstanding high-frequency impacts and shaft loads during gearbox operation, meeting the requirements of high-frequency rotation.
– Suitable Scenarios: Dedicated to Allison series transmission shaft systems, widely used in commercial vehicles, heavy trucks, construction machinery, mining equipment and other equipment equipped with Allison transmissions. It is used to support and reduce wear on key rotating components such as transmission input shafts, output shafts and gear shafts, undertaking the core tasks of support, wear reduction and vibration reduction. It can be used for original parts replacement, transmission repair and maintenance, and is suitable for complex working conditions such as heavy load, high frequency rotation and heavy oil contamination, providing stable support for transmission shaft system operation and helping equipment to operate efficiently.
