29422 Spherical Roller Thrust Bearing | M / E Types Available
The 29422 spherical roller thrust bearing is a large-size, heavy-duty thrust bearing designed for extreme axial loads and moderate radial loads. It provides reliable self-aligning performance to compensate for shaft deflection and installation misalignment, supporting low-friction, stable and long-term continuous operation. Available in 29422M and 29422E models, this bearing offers high-strength and durable thrust support for heavy industrial machinery.
29422 M / E Type Differences
29422M: Equipped with a solid machined brass cage, featuring 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 equipment requiring high operational stability.
29422E: Adopts an optimized enhanced roller structure with improved load distribution and higher dynamic load capacity. It delivers better rotational flexibility and heat dissipation than the M type, perfectly suited for high-speed and variable-load heavy-duty mechanical systems.
Material Introduction
Bearing Steel (GCr15): 29422 thrust bearings adopt standard GCr15 high-carbon chromium bearing steel. After professional heat treatment, the material achieves high hardness, excellent wear resistance and strong fatigue resistance, retaining stable rotational accuracy and structural rigidity under long-term heavy axial loads with excellent cost performance.
Stainless Steel (Optional): Custom stainless steel 29422 bearings provide superior rust-proof, anti-oxidation and weak corrosion resistance. They effectively resist moisture and industrial contaminants to prevent premature bearing failure, suitable for humid, sanitary and lightly corrosive working environments.
Product Features
Excellent 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
29422 spherical roller thrust bearings are widely applied in heavy-duty gearboxes, mining machinery, cement equipment, large industrial fans, hydraulic systems and construction machinery. 29422M suits continuous constant-load equipment; 29422E is optimal for high-speed and variable-load industrial systems. Stainless steel versions apply to food machinery, medical equipment and high-humidity working conditions.
