NSK 6207-2RS/NR Rubber Sealed Single Row Deep Groove Ball Bearing 35x72x17mm

The NSK 6207-2RS-NR is a precision deep groove ball bearing (35x72x17mm) engineered for applications requiring both maximum contamination protection and secure axial location. Manufactured to NSK's stringent Japanese quality standards, this bearing features contact rubber seals on both sides (2RS) that provide an effective barrier against moisture, dust, and abrasive particles while securely retaining the factory-applied grease for extended lubrication intervals. The NR suffix denotes an integral snap ring groove on the outer diameter, complete with a snap ring that enables simple and positive axial positioning within the housing—eliminating the need for complex retaining mechanisms and simplifying assembly in space-constrained applications. This combination of robust sealing and integrated location makes the 6207-2RS-NR particularly well-suited for electric motors, gearboxes, pumps, agricultural machinery, and conveyor systems where both environmental protection and compact mounting are essential. Constructed from premium bearing steel with optimized raceway geometry, this sealed bearing delivers reliable, low-vibration operation and extended service life, providing engineers and maintenance professionals with a durable, fit-and-forget solution for challenging operating conditions.
