29420 Spherical Roller Thrust Bearing | M / E Types Available
The 29420 spherical roller thrust bearing is a large-size heavy-duty thrust bearing engineered for extreme axial loads and moderate radial loads. It features reliable self-aligning performance to compensate for shaft deflection and installation misalignment, enabling low-friction, stable and long-term continuous operation. Available in 29420M and 29420E models, this bearing delivers high-strength, durable thrust support for heavy industrial machinery.
29420 M / E Type Differences
29420M: Fitted with a solid machined brass cage with high structural rigidity and outstanding impact resistance. It runs stably under continuous heavy loads and harsh working conditions with low wear, ideal for long-cycle, constant-load industrial equipment that requires high operational stability.
29420E: Adopts an optimized enhanced roller structure with upgraded load distribution and higher dynamic load capacity. It provides improved rotational flexibility and heat dissipation compared with the M type, perfectly suited for high-speed and variable-load heavy-duty mechanical systems.
Material Introduction
Bearing Steel (GCr15): 29420 thrust bearings adopt standard GCr15 high-carbon chromium bearing steel. After precise heat treatment, the material gains high hardness, excellent wear resistance and strong fatigue resistance, maintaining stable rotational accuracy and structural rigidity under long-term heavy axial loads with great cost performance.
Stainless Steel (Optional): Custom stainless steel 29420 bearings offer excellent rust-proof, anti-oxidation and weak corrosion resistance. They effectively resist moisture and industrial contaminants to avoid premature bearing failure, suitable 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 types meet constant-load and high-speed operation requirements. Low friction and efficient heat dissipation extend bearing service life. High mechanical strength ensures long-term stable working performance.
Application Scenarios
29420 spherical roller thrust bearings are widely used in heavy-duty gearboxes, mining machinery, cement production equipment, large industrial fans, hydraulic systems and construction machinery. 29420M suits continuous constant-load equipment; 29420E is optimal for high-speed and variable-load industrial systems. Stainless steel versions apply to food machinery, medical equipment and high-humidity working conditions.
