Engineered to deliver exceptional reliability in environments where radial space is restricted, the 6917-2RS is a premium thin-section deep groove ball bearing. Featuring dual nitrile rubber contact seals (2RS), this bearing is specifically designed to lock in factory lubrication while creating an impenetrable barrier against environmental contaminants like dust, moisture, and manufacturing debris. While rubber seals introduce a nominal increase in friction compared to open bearings, they drastically extend the service life of the component in exposed conditions. This makes the 6917-2RS an invaluable asset for 85mm bore applications, including packaging machinery, medium-duty gearboxes, and automated material handling systems.
