29238 Spherical Roller Thrust Bearing | M / E Types Available
The 29238 spherical roller thrust bearing is a large-sized heavy-duty thrust bearing, specially designed for extreme axial loads and moderate radial loads. It features reliable self-aligning performance to compensate for shaft deflection and installation errors, ensuring low-friction, stable and long-service operation. Available in 29238M and 29238E types, it provides sturdy thrust support for heavy industrial machinery and mechanical systems.
29238 M / E Type Differences
29238M: Adopts a solid machined brass cage with high structural rigidity and excellent impact resistance. It runs stably under continuous heavy loads and harsh working conditions with low abrasion, ideal for long-cycle, high-stability industrial equipment operation.
29238E: Equipped with an optimized enhanced roller structure, featuring improved load distribution and higher dynamic load capacity. It delivers better rotational flexibility and heat dissipation than the M type, perfectly suitable for high-speed and variable-load heavy-duty industrial applications.
Material Introduction
Bearing Steel (GCr15): 29238 thrust bearings adopt standard GCr15 high-carbon chromium bearing steel. With professional heat treatment process, the material gains high hardness, outstanding wear resistance and strong fatigue resistance, maintaining stable rotational precision and structural rigidity under long-term heavy axial loads with great cost performance.
Stainless Steel (Optional): Custom stainless steel 29238 bearings possess excellent anti-rust, anti-oxidation and weak corrosion resistance. They effectively resist moisture and industrial contaminants, avoiding premature bearing failure, suitable for humid, sanitary and lightly corrosive working environments.
Product Features
Excellent self-aligning capability offsets installation deviation 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 coefficient and efficient heat dissipation extend bearing service life. High mechanical strength ensures stable long-term working performance.
Application Scenarios
29238 spherical roller thrust bearings are widely used in heavy-duty gearboxes, mining machinery, cement production equipment, large industrial fans, hydraulic systems and construction machinery. 29238M fits continuous constant-load equipment; 29238E is optimal for high-speed and variable-load industrial systems. Stainless steel versions apply to food machinery, medical equipment and high-humidity working conditions.
