29228 Spherical Roller Thrust Bearing | M / E Types Available
The 29228 spherical roller thrust bearing is a heavy-duty thrust bearing built to handle high axial loads and moderate radial loads. It features outstanding self-aligning performance to compensate for shaft deflection and installation errors, ensuring low-friction, stable and long-term operation. Available in 29228M and 29228E models, this bearing delivers reliable thrust support for a wide range of heavy industrial equipment.
29228 M / E Type Differences
29228M: Comes with a solid machined brass cage with high structural rigidity and strong impact resistance. It maintains stable operation under continuous heavy loads and harsh working environments with low wear, ideal for long-cycle, high-stability industrial applications.
29228E: Features an optimized enhanced roller structure with improved load distribution and higher dynamic load capacity. Compared with the M type, it provides better rotational flexibility and heat dissipation, perfectly suited for high-speed and variable-load heavy-duty machinery.
Material Introduction
Bearing Steel (GCr15): GCr15 high-carbon chromium bearing steel is the standard material for 29228 bearings. Through precise heat treatment, it obtains high hardness, excellent wear resistance and strong fatigue resistance, keeping stable precision and structural rigidity under long-term heavy axial loads with reliable cost performance.
Stainless Steel (Optional): Custom stainless steel 29228 bearings offer superior rust-proof, anti-oxidation and weak corrosion resistance. They effectively resist moisture and industrial contaminants, preventing premature bearing failure for humid, sanitary and lightly corrosive working conditions.
Product Features
Excellent self-aligning capability compensates for installation deviation and operational deflection. High axial load capacity with stable radial load tolerance. Two structural designs meet constant-load and high-speed operation requirements. Low friction and efficient heat dissipation extend service life. High mechanical strength ensures consistent long-term performance.
Application Scenarios
29228 spherical roller thrust bearings are widely used in heavy-duty gearboxes, mining machinery, cement equipment, large industrial fans, hydraulic systems and construction machinery. 29228M fits continuous constant-load equipment; 29228E is optimal for high-speed and variable-load industrial systems. Stainless steel versions apply to food machinery, medical equipment and high-humidity working environments.
