22311 Spherical Roller Bearing | CA / CC / K Types Available
The 22311 spherical roller bearing is a heavy-duty self-aligning rolling bearing built for high radial loads and moderate bidirectional axial loads. It excels at compensating shaft misalignment and operational deflection, featuring low friction, anti-vibration stability and consistent long-term operation. Offered in CA, CC, and K structural types with GCr15 bearing steel and stainless steel options, the 22311 bearing adapts to a wide range of standard and harsh industrial applications.
22311 CA / CC / K Type Differences
22311CA: Adopts solid machined brass cage and symmetrical roller structure with inner ring middle ribs. It delivers high rigidity, low wear and reliable high-speed performance, ideal for continuous heavy-load and high-precision industrial equipment.
22311CC: Features stamped steel cage and movable middle spacer without inner ring ribs. It provides larger grease volume, lower friction and better heat dissipation, offering stable and cost-effective operation for general heavy-duty machinery.
22311K: Equipped with 1:12 tapered inner bore, suitable for adapter sleeve mounting. It supports quick assembly, disassembly and convenient shaft adjustment, perfect for equipment requiring regular maintenance and replacement.
Material Introduction
Bearing Steel (GCr15): GCr15 high-carbon chromium bearing steel is the standard material for 22311 bearings. With professional heat treatment, it achieves high hardness, superior wear resistance and strong fatigue resistance. It maintains stable rotational accuracy and structural rigidity under long-term heavy-load operation with excellent cost performance.
Stainless Steel: Stainless steel 22311 bearings provide excellent rust-proof, anti-oxidation and weak corrosion performance. They resist moisture and minor industrial contamination effectively, avoiding premature wear and precision loss, suitable for humid, sanitary and lightly corrosive working environments.
Product Features
Powerful self-aligning capability eliminates shaft deflection and installation errors. High radial load capacity with stable bidirectional axial load resistance. Multiple structural designs meet high-precision, economical and easy-install demands. Low friction, excellent heat dissipation and strong anti-vibration performance. Dual material grades ensure wide adaptability for diverse industrial conditions.
Application Scenarios
22311 spherical roller bearings are widely applied in mining machinery, industrial fans, conveyor systems, construction equipment, agricultural machinery and heavy-duty transmission systems. 22311CA is ideal for continuous heavy-load precision equipment; 22311CC fits general industrial machinery; 22311K suits frequently maintained and adjustable shaft systems. Stainless steel versions are perfect for food machinery, medical devices and high-humidity working scenarios.
