23128 Spherical Roller Bearing | CA / CC / K Types Available
The 23128 spherical roller bearing is a heavy-duty self-aligning roller bearing optimized for high radial loads and moderate bidirectional axial loads. It boasts excellent self-aligning performance to compensate for shaft misalignment and operational deflection, supporting low-friction, stable and anti-vibration operation. Available in CA, CC and K structural types with GCr15 and stainless steel options, the 23128 bearing offers durable, long-term performance for diverse heavy industrial working conditions.
23128 CA / CC / K Type Differences
23128CA: Features a solid machined brass cage and symmetrical roller structure with inner ring middle ribs. It delivers high rigidity, low wear and stable high-speed operation, perfectly suited for continuous heavy-load and high-precision industrial equipment.
23128CC: Adopts a stamped steel cage and movable middle spacer without inner ring ribs. It has larger internal grease volume, lower friction and superior heat dissipation, providing stable and cost-effective performance for general heavy-duty machinery.
23128K: Designed with a standard 1:12 tapered inner bore for adapter sleeve mounting. It enables easy assembly, disassembly and flexible shaft adjustment, ideal for equipment requiring regular maintenance and routine servicing.
Material Introduction
Bearing Steel (GCr15): GCr15 high-carbon chromium bearing steel serves as the standard material for 23128 bearings. With professional heat treatment, it gains high hardness, outstanding wear resistance and strong fatigue resistance. It retains stable rotational accuracy and structural rigidity during long-term heavy-load operation with excellent cost performance.
Stainless Steel: Stainless steel 23128 bearings offer reliable rust-proof, anti-oxidation and weak corrosion resistance. They effectively resist moisture and industrial contaminants, avoiding precision loss and premature bearing failure, adapting well to humid, sanitary and lightly corrosive working scenarios.
Product Features
Excellent self-aligning capability compensates for shaft deflection and installation errors. High radial load capacity with stable bidirectional axial load tolerance. Multiple structural types meet high-precision, economical and easy-maintenance demands. Low friction coefficient, efficient heat dissipation and strong anti-vibration stability. Dual material grades support wide adaptability for complex industrial environments.
Application Scenarios
23128 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. 23128CA fits continuous heavy-load precision equipment; 23128CC suits general heavy industrial machinery; 23128K is optimal for frequently maintained shaft systems. Stainless steel versions are ideal for food machinery, medical devices and high-humidity working environments.
