29412 Spherical Thrust Roller Bearing | 29412E And 29412MB Cage Features And Applications
The 29412 is a high-performance single-row spherical thrust roller bearing with standard dimensions of 60×130×31mm. Specially engineered for heavy axial load conditions, this thrust roller bearing delivers outstanding self-aligning ability, high structural rigidity and low-friction stable operation. It effectively compensates shaft and housing misalignment, absorbs axial mechanical vibration and shock loads, and supports long-term continuous heavy-thrust operation. Ideal for vertical heavy-load machinery and hydraulic transmission systems, the 29412 series includes two mainstream models: 29412E with stamped steel cage and 29412MB with solid brass cage, meeting standard and harsh industrial operating requirements.
29412E Bearing (Stamped Steel Cage)
29412E features a high-strength stamped steel cage, serving as the universal and cost-effective option for standard industrial environments. The optimized lightweight steel structure maximizes internal bearing space, allows denser roller layout, and improves overall axial load capacity and limiting speed. With a low friction coefficient and excellent wear resistance, this bearing maintains stable cyclic performance under medium-speed and continuous heavy-thrust working conditions. Adopting standardized manufacturing processes, it offers reliable quality, strong versatility and great mechanical fatigue resistance. 29412E is widely used for general heavy machinery, providing consistent long-term operation while optimizing equipment operating costs.
29412MB Bearing (Solid Brass Cage)
29412MB adopts a precision one-piece machined solid brass cage, designed for extreme heavy-duty, high-temperature and high-shock working scenarios. The high-rigidity integral brass cage provides superior thermal stability, anti-deformation and anti-fatigue performance compared with conventional steel cages. It ensures accurate roller guidance, effectively reducing friction heat and running noise during long-duration uninterrupted high-load operation. Resistant to structural deformation under high temperature, heavy pressure and frequent impact loads, this model maintains stable rotational precision and extends service life significantly. Featuring ultra-high reliability and corrosion resistance, 29412MB is the premium solution for critical core industrial equipment that requires zero-failure continuous operation.
Industrial Applications
29412 series spherical thrust bearings are widely used for heavy axial load support and positioning in industrial transmission systems. 29412E is suitable for general heavy-duty equipment including medium and large industrial pumps, vertical gear reducers, conventional construction machinery and common industrial rotating devices. 29412MB adapts to rigorous working conditions such as mining auxiliary equipment, vertical grinding mills, large hydraulic systems and high-temperature processing machinery, stable enough for high-intensity operation with complex thermal and shock loads.
Product Summary: The 29412 spherical thrust roller bearing combines excellent self-aligning performance and super heavy-thrust capacity. 29412E delivers stable, cost-effective universal performance for standard working conditions, while 29412MB provides high rigidity and extreme durability for harsh industrial environments. The two configurations fully cover mainstream medium and heavy-thrust industrial application scenarios.
