24028 Spherical Roller Bearing | CA / CC / K Types Available
The 24028 spherical roller bearing is a large-bore, heavy-duty self-aligning roller bearing engineered for ultra-high radial loads and moderate bidirectional axial loads. It features excellent self-aligning performance to compensate for shaft misalignment and operational deflection, delivering low-friction, stable and vibration-resistant operation. Available in CA, CC and K types with GCr15 and stainless steel options, the 24028 bearing provides durable, high-reliability performance for heavy industrial equipment.
24028 CA / CC / K Type Differences
24028CA: Equipped with a solid machined brass cage and symmetrical roller structure with inner ring middle ribs. It offers high structural rigidity, low wear and consistent high-speed stability, ideal for continuous heavy-load and high-precision industrial applications.
24028CC: Adopts a stamped steel cage and movable middle spacer without inner ring ribs. It features larger internal grease capacity, lower friction and superior heat dissipation, delivering stable and cost-effective performance for general heavy-duty machinery.
24028K: Designed with a standard 1:12 tapered inner bore for adapter sleeve mounting. It enables fast assembly, disassembly and flexible shaft adjustment, perfect for equipment requiring regular maintenance and routine servicing.
Material Introduction
Bearing Steel (GCr15): GCr15 high-carbon chromium bearing steel is the standard material for 24028 bearings. After professional heat treatment, it achieves high hardness, outstanding wear resistance and strong fatigue resistance, maintaining stable rotational accuracy and structural rigidity during long-term heavy-load operation with excellent cost performance.
Stainless Steel: Stainless steel 24028 bearings provide excellent rust-proof, anti-oxidation and weak corrosion resistance. They effectively resist moisture and industrial contaminants, preventing precision loss and premature bearing failure, suitable for humid, sanitary and lightly corrosive working environments.
Product Features
Superior self-aligning capability offsets shaft deflection and installation errors. Ultra-high radial load capacity with stable bidirectional axial load tolerance. Multiple structural designs meet high-precision, economical and easy-maintenance demands. Low friction and efficient heat dissipation extend service life. Dual material grades ensure strong adaptability for complex industrial scenarios.
Application Scenarios
24028 spherical roller bearings are widely applied in mining machinery, cement production equipment, heavy-duty conveyor systems, large industrial fans, construction machinery and heavy transmission systems. 24028CA suits continuous heavy-load precision equipment; 24028CC fits general heavy industrial machinery; 24028K is optimal for frequently maintained shaft systems. Stainless steel versions apply to food machinery, medical devices and high-humidity working conditions.
