29222 Spherical Roller Thrust Bearing | M / E Types Available
The 29222 spherical roller thrust bearing is a heavy-duty thrust bearing specially designed to withstand high axial loads and moderate radial loads. It features superior self-aligning performance to compensate for mounting deviation and shaft deflection, delivering low-friction, stable and durable operation. Available in 29222M and 29222E types with premium bearing steel materials, it provides reliable thrust support for various heavy industrial mechanical systems.
29222 M vs E Type Differences
29222M: Equipped with a solid machined brass cage, featuring high structural rigidity, strong impact resistance and stable high-load operation. It adapts to continuous long-term operation and harsh working conditions, with low wear rate and long service life, ideal for high-stability industrial scenarios.
29222E: Adopts an optimized enhanced roller structure with improved load distribution. It upgrades dynamic load capacity compared with M type, features higher rotation flexibility and better heat dissipation, suitable for high-speed and variable-load heavy-duty equipment operation.
Material Introduction
Bearing Steel (GCr15): Standard material for 29222 thrust bearings. After precise quenching and tempering heat treatment, it achieves ultra-high hardness, excellent wear resistance and strong contact fatigue resistance. It maintains stable precision and structural rigidity under long-term heavy axial load operation with outstanding cost performance.
Stainless Steel (Optional): Custom stainless steel 29222 bearings have excellent rust-proof, anti-oxidation and weak corrosion resistance. They effectively resist moisture, dust and industrial corrosive media, avoiding precision failure, perfect for humid, sanitary and special industrial environments.
Product Features
Excellent self-aligning performance eliminates installation and operation deviation errors. Super strong axial load capacity with stable auxiliary radial load resistance. Two structural types meet high-stability and high-load-speed working demands. Low friction coefficient and efficient heat dissipation extend service life. High hardness and fatigue resistance ensure long-term stable operation.
Application Scenarios
29222 spherical roller thrust bearings are widely used in heavy-duty gearboxes, mining equipment, cement machinery, large fan shafts, hydraulic machinery, construction machinery and heavy rotating equipment. 29222M is suitable for constant-load, continuous working equipment; 29222E fits high-speed and variable-load industrial systems. Stainless steel versions apply to food processing, medical and high-humidity corrosive environments.
