It is mainly composed of components such as the wheel axle body, bearings, sealing devices and shock absorption systems. The functions and importance of these components are explained below: Wheel axle body: The wheel axle body is the main part of the lawn mower wheel axle structure. It is usually made of high-strength, low-weight materials, such as heat-treated steel. Its function is to support the weight of the entire lawn mower and transmit power from the engine to the cutting device of the lawn mower. The design of the wheel axle body is crucial to the durability and operating efficiency of the lawn mower; Bearing: The bearing is a rotating component installed on the wheel axle body, which allows the wheel axle to reduce friction and wear when rotating. The function of the bearing is to ensure that the wheel axle can rotate smoothly while bearing the load generated by the lawn mower during operation. Using high-quality bearings can significantly extend the service life of the lawn mower. Sealing device: The sealing device is located around the bearing to prevent grease leakage and dust from entering the bearing. This is crucial to protecting the bearings from contamination and wear, which will reduce the performance and life of the bearings.
