Product Description
SKF 2209 EKTN9/C3 self-aligning ball bearing is specifically engineered for industrial machinery requiring angular compensation and high-speed rotation. With a 45 mm inside diameter and 85 mm outside diameter, this double-row bearing delivers excellent radial load distribution and durability.
The bearing incorporates steel balls providing a hardened contact surface optimized for boundary and mixed lubrication regimes. The non-metallic cage design reduces friction and centrifugal load, supporting operation up to 10000 rpm.
This open-ended bearing features a tapered bore allowing press or adaptor mounting, ensuring secure and precise installation. Its C3 internal clearance permits thermal expansion during load conditions, enhancing reliability during continuous use.
Typical industrial applications include conveyor drive shafts with shaft misalignment, gearboxes requiring angular correction, agricultural machinery with fluctuating loads, industrial fans, and blowers operating at elevated speeds.
The self-aligning feature allows the inner ring to tilt relative to the outer ring, accommodating shaft deflection and reducing misalignment stresses. Lubrication and contamination control are to be managed externally due to the open end design.
Double-row ball bearing for enhanced radial load capacity. C3 clearance for thermal expansion handling. Steel balls for robust wear resistance and contact performance. Non-metallic cage to reduce friction and support high-speed operation.
Open end bearing requires external lubrication strategy. Tapered bore enables adaptor or press-fit installation. High limiting speed rating of 10000 rpm. Dynamic load rating of 32.5 kN and static rating of 10.6 kN. Self-aligning design corrects shaft misalignment during use.
This product is ideal for use in industrial, manufacturing, agricultural, conveyor, gearbox, and HVAC applications requiring durable, high-performance rotary bearings. Browse EnvMart for related SKF rotor bearings and accessories to support your machinery maintenance and operational efficiency.
