22309 Spherical Roller Bearing | CA / CC / K Types Available
The 22309 spherical roller bearing is a heavy-duty self-aligning bearing designed for high radial loads and moderate bidirectional axial loads. Featuring superior self-aligning performance, low friction, stable high-speed operation and excellent shock resistance, it effectively compensates for shaft misalignment and installation deflection. Available in CA, CC and K structural types with GCr15 bearing steel and stainless steel materials, the 22309 bearing delivers durable and precise performance for complex industrial working conditions.
22309 CA / CC / K Type Differences
22309CA: Equipped with solid machined brass cage, symmetrical roller structure and inner ring with middle ribs. It features high rigidity, low wear and stable high-speed operation, ideal for heavy-load, high-precision and long-duration running scenarios.
22309CC: Adopts stamped steel cage with a movable middle spacer, no inner ring ribs. It has larger internal grease space, lower friction and better heat dissipation, offering cost-effective performance for general heavy-duty industrial applications.
22309K: Features a 1:12 tapered inner bore, matching adapter sleeves for installation. It is easy to assemble and disassemble, suitable for shafts requiring frequent maintenance and positioning adjustment.
Material Introduction
Bearing Steel (GCr15): GCr15 high-carbon chromium bearing steel is the standard material for 22309 bearings. After professional heat treatment, it achieves high hardness, outstanding wear resistance and strong fatigue resistance. It maintains stable rotational accuracy and structural rigidity under long-term heavy-load operation, providing high cost performance for most industrial machinery.
Stainless Steel: Stainless steel 22309 bearings provide excellent rust-proof, anti-oxidation and weak corrosion resistance. They effectively resist moisture and minor industrial contamination, avoiding precision loss and premature failure, perfectly suited for humid, sanitary and lightly corrosive working environments.
Product Features
Powerful self-aligning capability compensates for shaft deflection and installation errors. Excellent heavy radial load capacity with stable axial load tolerance. Multiple structural types meet high-precision, cost-effective and easy-installation demands. Low friction, good heat dissipation and strong anti-vibration performance. Dual material grades and wide compatibility with industrial equipment.
Application Scenarios
22309 spherical roller bearings are widely applied in industrial fans, mining machinery, conveyor systems, construction equipment, agricultural machinery and heavy-duty transmission devices. 22309CA suits high-precision heavy-load equipment; 22309CC is for general industrial machinery; 22309K is ideal for equipment requiring convenient assembly and maintenance. Stainless steel versions fit food machinery, medical devices and high-humidity working scenarios.
