29312 Spherical Thrust Roller Bearing | 29312E And 29312MB Cage Features And Applications
The 29312 is a high-performance single-row spherical thrust roller bearing with standard dimensions of 60×110×30mm. Designed for heavy axial load support and dynamic self-alignment, this bearing solves common pain points of traditional thrust bearings, including poor misalignment tolerance and unstable heavy-load operation. It features high rigidity, low friction and excellent vibration resistance, effectively compensating shaft and housing deflection while enduring continuous heavy thrust and intermittent shock loads. Suitable for various vertical and high-thrust industrial machinery, the 29312 series provides two mainstream models: 29312E with stamped steel cage and 29312MB with solid brass cage, for universal and harsh working conditions respectively.
29312E Bearing (Stamped Steel Cage)
29312E adopts a high-strength stamped steel cage with optimized internal roller distribution, serving as the economical and universal version of the 29312 series. The lightweight yet tough steel cage maximizes internal space utilization, increases roller arrangement density, and effectively improves axial load capacity and limiting speed. With low friction coefficient, outstanding wear resistance and stable cyclic operation performance, this model runs steadily under medium-speed and continuous heavy-thrust working conditions. Manufactured with standardized processes, it offers strong versatility and excellent cost performance. It effectively resists daily mechanical abrasion and fatigue, making it the ideal choice for conventional industrial equipment that requires long-term stable operation and cost control.
29312MB Bearing (Solid Brass Cage)
29312MB is configured with a precision one-piece machined solid brass cage, representing the premium heavy-duty solution for extreme environments. The high-rigidity integral brass cage delivers superior high-temperature resistance, structural stability and anti-fatigue performance compared with ordinary steel cages. It ensures precise roller guidance, greatly reducing friction heat and running noise during long-duration uninterrupted operation. The brass cage is not prone to deformation under high temperature, heavy pressure and frequent shock loads, maintaining consistent operational accuracy and greatly extending service life. This high-reliability model is specially designed for critical industrial equipment that requires zero-failure continuous operation under harsh working conditions.
Industrial Applications
29312 series spherical thrust bearings are widely used for heavy axial load positioning and support in industrial transmission systems. 29312E is suitable for general heavy-duty equipment including small and medium-sized industrial pumps, vertical reducers, conventional construction machinery and general industrial rotating equipment. 29312MB is applied in rigorous working scenarios such as mining auxiliary equipment, vertical grinding machinery, hydraulic transmission systems and high-temperature processing equipment, adapting to high-intensity operation with shock and thermal loads.
Product Summary: The 29312 spherical thrust roller bearing features reliable self-aligning performance and strong heavy-thrust capacity. 29312E provides stable, cost-effective universal performance for standard working conditions, while 29312MB offers high rigidity and extreme durability for harsh environments. The two configurations fully cover mainstream medium and heavy-thrust industrial application scenarios.
