5313/C3 Double-Row Angular Contact Ball Bearing 3313-2RS 3313ZZ-Durable Bearing Steel Material 65x140x58.7mm
Product Description
5313-C3/2RS is a Double Row Angular Contact Ball Bearing with both sides Rubber Sealed (2RS denotes rubber seals that block contaminants and retain lubricant), C3 Radial Internal Clearance, and is pre-lubricated with high-performance grease. The C3 clearance provides extra internal space between the bearing rings to accommodate thermal expansion during high-speed or heavy-load operation, avoiding friction-induced damage. The rubber seals effectively isolate dust, moisture, and debris from entering the bearing, while preserving grease to extend service life and reduce maintenance frequency. This double-row design enables the bearing to withstand higher radial loads and significant bidirectional axial loads, making it ideal for applications requiring combined load support and structural rigidity.
Interchange: 5313-2RS/C3, 5313.2RS.C3, 5313RS/C3 (compatible single-side to double-side seal variants), 5313ZZ/C3 (metal-sealed equivalent for less harsh environments), cross-brand models matching "double row angular contact + 2RS seal + C3 clearance" (e.g., SKF 5313-2RS1/C3, NSK 5313DDU/C3)
Applications: Machine Tool Spindles, Industrial Pumps & Air Compressors, Automotive Transmission Components, Heavy-Duty Ventilation Fans, Printing Machinery, Textile Mill Rolling Equipment, Construction Machinery (e.g., small excavator hydraulic parts), and Precision Drivetrains where reliable combined radial-axial load performance and contamination resistance are required.
