29316Spherical Roller Bearings

29316 Spherical Thrust Roller Bearing | 29316E And 29316MB Cage Features And Applications

The 29316 is a high-performance single-row spherical thrust roller bearing with standard dimensions of 80×140×36mm. Featuring excellent self-aligning performance and ultra-strong axial load capacity, this bearing is professionally designed for vertical heavy-load mechanical systems. It effectively compensates shaft and housing misalignment, absorbs axial vibration, and withstands long-term continuous heavy thrust and intermittent shock loads. With high rigidity and low-friction stable operation, it is widely used in various medium and large industrial thrust equipment. The 29316 series includes two classic configurations: 29316E stamped steel cage model and 29316MB solid brass cage model, adapting to conventional and harsh industrial working conditions.

29316E Bearing (Stamped Steel Cage)

29316E adopts a high-strength stamped steel cage with optimized internal roller arrangement, serving as the universal cost-effective model in the series. The lightweight and high-toughness steel cage improves internal space utilization, increases roller density, and effectively enhances axial load capacity and limiting operating speed. With low friction coefficient, excellent wear resistance and stable cyclic operation, this bearing runs steadily under medium-speed and heavy-thrust working conditions. Adopting standardized industrial production, it features strong versatility and stable quality, resisting daily mechanical abrasion and operational fatigue. It is the preferred economical solution for general heavy-duty equipment that requires long-term stable operation and cost optimization.

29316MB Bearing (Solid Brass Cage)

29316MB is fitted with a precision one-piece machined solid brass cage, a premium heavy-duty version for extreme working environments. The high-rigidity integral brass cage outperforms steel cages in high-temperature resistance, structural stability and anti-fatigue performance. It achieves precise roller guidance, effectively reducing friction heat and running noise during long-duration uninterrupted heavy-load operation. The brass structure is resistant to deformation under high temperature, heavy pressure and frequent shock loads, maintaining consistent operational accuracy and greatly extending service life. With ultra-high reliability and anti-corrosion performance, this model is suitable for core critical equipment that requires zero-failure continuous operation.

Industrial Applications

29316 series spherical thrust bearings are widely used for heavy axial load support in industrial transmission systems. 29316E is applicable to general heavy-duty machinery including medium and large industrial pumps, vertical reducers, conventional construction equipment and ordinary rotating machinery. 29316MB is designed for harsh working scenarios such as mining lifting equipment, vertical grinding mills, large hydraulic systems and high-temperature industrial machinery, adapting to high-intensity operation with complex shock and thermal loads.

Product Summary: The 29316 spherical thrust roller bearing features reliable self-aligning capability and superior heavy-thrust bearing performance. 29316E provides stable, cost-effective universal performance for standard working conditions, while 29316MB delivers high rigidity and extreme durability for harsh industrial environments. The two configurations fully cover mainstream medium and heavy-thrust industrial application scenarios.
