22313 EK

The 22313 EK spherical roller bearing is a robust, self-aligning solution engineered for heavy-duty applications prone to shaft misalignment or dynamic load shifts. Featuring a symmetrical barrel-shaped roller design and an EK-style machined brass cage, this bearing excels in handling combined radial and axial loads while compensating for mounting errors up to 3° in industrial fans, conveyor systems, and pulp/paper machinery. Its heat-treated chromium steel construction, enhanced with controlled carbonitriding, ensures prolonged fatigue life under high-vibration environments like mining crushers or steel mill gearboxes. The 22313 EK's optimized internal geometry minimizes edge stress concentrations, enabling stable operation at speeds up to 2,400 RPM and temperatures ranging from -20°C to +150°C. Pre-lubricated with high-temperature grease and equipped with a solid brass cage for debris resistance, it adheres to ISO 15:2017 standards, offering simplified maintenance and backward compatibility with legacy industrial setups.
