2210 E-2RSK Double Row Self-Aligning Ball Bearing Double 2RSK Rubber Seal 50x90x23mm Farm Conveyor Motor Equipment

The 2210 E-2RSK double row self-aligning ball bearing is equipped with reinforced E stamped steel cage and double-sided 2RSK heavy-duty rubber seals. Spherical outer ring raceway provides strong self-aligning ability to offset shaft deflection and mounting misalignment, while integrated double lip seals block mud, dust and water splashes. It bears radial load plus minor bidirectional axial load, widely used on agricultural machinery, conveyors and dust-prone industrial motors.

• Spherical outer raceway allows large self-aligning angle, tolerates shaft and housing misalignment
• Thickened 2RSK double lip seals effectively isolate mud, crop debris, dust and cooling liquid
• Optimized E stamped steel cage holds steel balls stably under medium speed vibration
• Pre-filled long service grease inside sealed cavity, lower maintenance frequency
• Compact double-row structure delivers balanced radial and light axial bearing capacity
• Open type 2210E and C3 enlarged clearance versions can be customized

This sealed self-aligning ball bearing is widely applied in:

• Farm harvesters, grain conveyors and agricultural rotary transmission assemblies
• Light industrial conveyor rollers, textile and packaging machinery
• Small driving motors operating in dusty, splash-prone workshop environments
• General light-load equipment requiring self-aligning and good sealing performance

• 25+ years experience in self-aligning ball bearing manufacturing
• Exported to 50+ countries worldwide
• Rich OEM bulk order experience for 2RSK sealed self-aligning bearings
