Product Details
The Nachi radial ball bearing 6303-2RS is a double sealed bearing with a 17mm bore and a 47mm outer diameter (OD). It offers moderate load-carrying capacity in both radial and axial directions, making it suitable for high-speed and high-accuracy applications. The bearing features rubber seals or metal shields on one or both sides to prevent dirt and contaminants from entering. When two seals or shields are used, the bearing is pre-lubricated with grease for its entire lifespan at the time of manufacture. This bearing, part of the 6000 to 6300 series with bore sizes ranging from 10 to 75 mm and the 6800 and 6900 series with bore sizes of 10 to 50 mm, enhances reliability through a newly designed seal and shield, as well as appropriate grease. Improved accuracy of components facilitates quiet rotation, while design considerations also contribute to cost and energy savings with lower power loss and stable running torque.
