23028 Spherical Roller Bearing | CA / CC / K Types Available
The 23028 spherical roller bearing is a large-bore, heavy-duty self-aligning bearing engineered for extreme radial loads and moderate bidirectional axial loads. It delivers reliable self-aligning performance to correct shaft misalignment and operational deflection, paired with low friction, stable rotation and strong anti-vibration performance. Offered in CA, CC and K configurations with GCr15 and stainless steel options, the 23028 bearing ensures long-term stable operation in heavy industrial working conditions.
23028 CA / CC / K Type Differences
23028CA: Features a solid machined brass cage and symmetrical roller structure with inner ring middle ribs. It provides high rigidity, low wear and excellent high-speed stability, ideal for continuous heavy-load and high-precision industrial operation.
23028CC: Adopts a stamped steel cage and movable middle spacer without inner ring ribs. It has larger internal grease space, lower friction and better heat dissipation, delivering stable and cost-effective performance for general heavy-duty machinery.
23028K: Designed with a 1:12 tapered inner bore for adapter sleeve mounting. It supports easy installation, disassembly and shaft adjustment, perfectly suited for equipment requiring regular maintenance and frequent servicing.
Material Introduction
Bearing Steel (GCr15): GCr15 high-carbon chromium bearing steel is the standard material for 23028 bearings. Through professional heat treatment, it achieves high hardness, outstanding wear resistance and strong fatigue resistance. It maintains precise rotation and structural rigidity under long-term heavy-load operation with excellent cost performance.
Stainless Steel: Stainless steel 23028 bearings offer superior rust-proof, anti-oxidation and weak corrosion resistance. They effectively resist moisture and minor industrial contamination, preventing precision degradation and premature failure in humid, clean and lightly corrosive environments.
Product Features
Excellent self-aligning capability compensates for shaft deflection and installation errors. Ultra-strong radial load capacity with stable bidirectional axial load tolerance. Multiple structural types meet high-precision, economical and easy-maintenance demands. Low friction, efficient heat dissipation and robust anti-vibration performance. Dual material grades deliver wide adaptability for complex industrial scenarios.
Application Scenarios
23028 spherical roller bearings are widely applied in large mining equipment, cement machinery, heavy-duty conveyors, industrial fans, construction machinery and main transmission systems. 23028CA suits continuous heavy-load precision equipment; 23028CC fits general heavy industrial machinery; 23028K is optimal for frequently maintained shaft systems. Stainless steel versions are ideal for food machinery, medical equipment and high-humidity working environments.
