2. Da Tai Track Support Wheel Floating Oil Seal and Sealing System<\/h3>\n\n\n\n
The most fatal form of failure for the supporting wheel is oil leakage. Once the lubricating oil leaks, the internal bearings will be scrapped within a few hours due to dry friction\u3002<\/p>\n\n\n\n
- \n
- Sealing form: Double cone floating oil seal (usually metal floating seal) must be used. This sealing structure relies on two high hardness and high smoothness metal ring end faces to seal, which can effectively resist the invasion of mud, sand, and asphalt debris commonly found on the paving site.<\/li>\n\n\n\n
- Sealing material: High quality oil seal rings are usually made of chromium molybdenum alloy cast iron or bearing steel, and O-rings (rubber rings) should be selected from high temperature resistant and aging resistant fluororubber or nitrile rubber. Poor quality products usually use single pass skeleton oil seals or low-quality rubber, which are prone to failure and oil leakage in high temperature environments.<\/li>\n<\/ul>\n\n\n\n
3.Da Tai support wheel bearing configuration<\/h3>\n\n\n\n
The rotational flexibility of the supporting wheels determines the resistance of the walking system\u3002<\/p>\n\n\n\n
- \n
- Bearing type: Priority should be given to tapered roller bearing configuration. Compared with deep groove ball bearings, tapered roller bearings have higher radial and axial load-bearing capacity and can withstand the complex stresses generated by pavers operating on rough roads or slopes.<\/li>\n\n\n\n
- Clearance and accuracy: A well assembled supporting wheel should have a thick and smooth feel when rotating, without any jamming sensation, and have minimal axial clearance. If there is a feeling of “looseness” or abnormal noise during rotation, it indicates that the internal bearing accuracy is insufficient or the pre tightening force is not enough\u3002<\/li>\n<\/ul>\n\n\n\n
4. Appearance design and process details of Datai supporting wheel<\/h3>\n\n\n\n
Details often reflect the quality control level of Da Tai\u3002<\/p>\n\n\n\n
- \n
- Wheel structure: The support wheels of the paver are usually divided into single-sided wheels and double-sided wheels (selected according to the form of the track shoe slide rail). The shoulder (step) part of the high-quality wheel body has been strengthened and has high dimensional accuracy, which can prevent the track from “gnawing on the track” or derailing during walking.<\/li>\n\n\n\n
- Welding and surface: Check the joint between the end caps at both ends of the wheel body and the wheel body. High quality products should be welded smoothly without any air holes. The surface paint layer should have high adhesion, usually using epoxy resin paint, which can resist the corrosion of asphalt and road construction environment.<\/li>\n<\/ul>\n\n\n\n
5. Consider brand and after-sales support<\/h3>\n\n\n\n
- \n
- Ma’anshan Datai Machinery Technology Co., Ltd.: It is recommended to purchase directly through official channels or authorized distributors of the limited company to prevent the purchase of counterfeit products. Da Tai brand provides a clear warranty period (industry standards typically range from 6 months to 1 year or a certain amount of working time). Applied to Volvo (ABG) DYNAPAC CAT XCMG Sany Heavy Industry<\/li>\n\n\n\n
- Compatibility: Before purchasing, please make sure to check the installation hole distance, shaft diameter, and wheel body width between the model and the supporting wheel. Even small dimensional deviations can cause deformation of the track frame or track deviation.<\/li>\n<\/ul>\n\n\n\n

Choosing high-quality track support wheels for the paver directly affects the service life of the paver chassis and the smoothness of the paving operation. On equipment such as paving machines that require extremely high walking stability, the selection of supporting wheels needs to be particularly strict.
