23041457 bearing Allison spare parts

The Allison 23041457 bearing, as a core rotating support component of the Allison transmission, is hailed as the “smooth foundation” of the transmission shaft system. 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 23041457
– Material specifications: High-quality high-carbon chromium bearing steel (GCr15) or carburized bearing steel (G20CrNiMo) is selected, taking into account both hardness and toughness. It is processed by professional heat treatment process of quenching + tempering + grinding. The tensile strength is ≥1500MPa and the Rockwell hardness is controlled at HRC60-64. The inner and outer rings and rolling elements of the bearing are precision ground and polished, and the roughness reaches Ra≤0.1μm.
– Structure type: Deep groove ball bearing/cylindrical roller bearing (adapted as needed), with an integrated sealing structure and equipped with high-quality nitrile rubber (NBR) or fluororubber (FKM) seals; the rolling elements adopt a precision ball/roller design, which is strictly sorted and has high dimensional consistency. Combined with the cage (stamped steel plate/phenolic resin material), it can effectively guide the rolling elements to run smoothly and reduce operating noise (noise ≤55dB); the inner and outer rings of the bearing adopt a chamfered design.
– Dimensional parameters: inner diameter φ20-50mm, outer diameter φ47-110mm, width 12-27mm, chamfer size 1.5-2.5mm, dimensional tolerance controlled within GB/T 307.1-2017 P6 grade accuracy.
– Protective performance: Temperature resistance range -40℃ to 180℃; oil resistance grade conforms to GB/T 1226-2010 standard; impact resistance conforms to ISO 16750 standard; fatigue life ≥1000 hours.
– Applicable Scenarios: Dedicated to Allison series transmissions, widely used in commercial vehicles, heavy trucks, construction machinery and other equipment equipped with Allison transmissions. It is used to support and reduce wear on key rotating components such as transmission shafts, gears and output 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. It provides stable support for the operation of transmission shafts and helps the equipment operate efficiently.

Core product advantages:
