29318 Spherical Roller Thrust Bearing | M / E Types Available
The 29318 spherical roller thrust bearing is a heavy-duty, large-size thrust bearing engineered for ultra-high axial loads and secondary radial loads. It features excellent self-aligning performance to compensate for shaft deflection and installation misalignment, supporting low-friction, stable and long-term continuous operation. Available in 29318M and 29318E types, this bearing offers reliable and cost-effective thrust support for heavy industrial equipment.
29318 M / E Type Differences
29318M: Built with a solid machined brass cage, delivering high structural rigidity and strong impact resistance. It maintains stable operation under continuous heavy loads and harsh working conditions with low wear, ideal for long-cycle, constant-load industrial applications that require high stability.
29318E: Adopts an optimized enhanced roller structure with upgraded load distribution and higher dynamic load capacity. Compared with the M model, it provides superior rotational flexibility and heat dissipation, perfectly suited for high-speed and variable-load heavy-duty machinery systems.
Material Introduction
Bearing Steel (GCr15): Standard GCr15 high-carbon chromium bearing steel is used for 29318 thrust bearings. After precise heat treatment, it achieves high hardness, excellent wear resistance and strong fatigue resistance, retaining stable rotational accuracy and structural rigidity under long-term heavy axial loads with outstanding cost performance.
Stainless Steel (Optional): Custom stainless steel 29318 bearings provide reliable rust-proof, anti-oxidation and weak corrosion resistance. They effectively resist moisture, dust and industrial contaminants, preventing premature bearing failure for humid, sanitary and lightly corrosive working environments.
Product Features
Superior self-aligning capability offsets installation errors and operational deflection. Ultra-high axial load capacity with stable radial load tolerance. Two structural designs meet constant-load and high-speed operation demands. Low friction and efficient heat dissipation extend service life. High mechanical strength ensures consistent long-term stable performance.
Application Scenarios
29318 spherical roller thrust bearings are widely applied in heavy-duty gearboxes, mining machinery, cement equipment, large industrial fans, hydraulic systems and heavy construction machinery. 29318M suits continuous constant-load equipment; 29318E is optimal for high-speed and variable-load industrial systems. Stainless steel versions apply to food machinery, medical equipment and high-humidity working conditions.
