29230 Spherical Thrust Roller Bearing | 29230E / 29230MB Cage And Application
Core Keywords: 29230 bearing, 29230E, 29230MB, spherical thrust roller bearing, heavy duty thrust bearing
The 29230 is a high-performance single-row spherical thrust roller bearing with standard dimensions of 150×215×39mm. Designed specifically for heavy axial load bearing and self-aligning compensation, this bearing features low friction, high rigidity and stable thrust operation. It effectively accommodates housing misalignment, absorbs axial vibration and withstands long-term continuous heavy thrust loads, making it an essential core component for vertical heavy-duty industrial machinery. The 29230 series has two mainstream configurations: 29230E and 29230MB, with different cage structures to meet universal and high-reliability industrial working conditions.
29230E Bearing (Stamped Steel Cage)
29230E adopts a high-strength stamped steel cage with optimized roller arrangement and streamlined internal structure. The lightweight steel cage saves internal space, increases roller assembly density, and greatly enhances axial load capacity and limiting speed. Featuring low friction coefficient, excellent wear resistance and strong structural stability, this model supports continuous medium-speed operation under cyclic heavy thrust loads. With standardized manufacturing, high versatility and outstanding cost performance, 29230E is the universal standard version of the series. It resists daily mechanical abrasion and vibration, perfectly suitable for conventional heavy industrial equipment with stable operating demands.
29230MB Bearing (Solid Brass Cage)
29230MB is equipped with a one-piece machined solid brass cage, featuring high rigidity, high temperature resistance and superior fatigue resistance. The precision integral brass cage ensures accurate roller guidance, effectively reducing running noise and friction heat during long-duration high-load operation. Different from steel cages, the brass structure is not easy to deform under shock thrust loads and high-temperature harsh environments, maintaining consistent operational precision and stability. With ultra-high durability and anti-corrosion performance, 29230MB is a premium heavy-duty model, tailored for critical equipment requiring long service life and zero-failure continuous operation.
Industrial Applications
29230 series spherical thrust bearings are widely used for axial load support in heavy industrial machinery. 29230E is ideal for general heavy-duty equipment including large industrial pumps, vertical reducers, construction machinery and general metallurgical auxiliary equipment, meeting conventional high-thrust operating needs. 29230MB is applied in harsh and high-standard working scenarios such as mining lifting equipment, metallurgical vertical mills, large hydraulic machinery and heavy rotating machinery, adapting to high temperature, shock load and long-term uninterrupted operation.
Product Summary: 29230E delivers cost-effective and stable universal thrust performance for conventional working conditions, while 29230MB provides high rigidity, high temperature resistance and ultra-high reliability for harsh heavy-load scenarios. The two models cover most vertical heavy-thrust industrial mechanical operation demands.
