Construction Machinery Bearing Race, designed specifically for the travel mechanisms, slewing mechanisms or transmission systems of heavy-duty construction machinery such as excavators, loaders and bulldozers, is a key component of tapered roller bearings or cylindrical roller bearings. It cooperates with rolling elements to form a high-rigidity, low-friction rotating pair, supporting the heavy loads of the equipment while ensuring stable operation of rotating parts. The product is made of high-carbon chromium bearing steel, integrally formed by forging process with dense and defect-free blank structure, excellent strength and toughness, providing a stable foundation for subsequent heat treatment. After rough turning, the race is subjected to overall quenching + low-temperature tempering treatment, with high hardness and good dimensional stability, excellent contact fatigue strength and wear resistance, which can withstand heavy loads, impacts and alternating stresses for a long time without deformation, spalling or cracking. The raceway surface is precision ground and superfinished with extremely low surface roughness and high fit accuracy, which can effectively reduce rolling friction, reduce wear and noise, and improve the overall bearing life.
The race end face is precision ground with high flatness, tight installation fit, which can effectively transmit loads and prevent axial movement. The product has passed strict dimensional inspection, hardness inspection and non-destructive testing to ensure that all performance indicators meet the original equipment standards. At present, this model of bearing race is in stock, which can quickly respond to orders and provide stable supply guarantee, making it an ideal accessory for the maintenance and repair of construction machinery in mining, construction, water conservancy and other fields.
