FAG 6303ZR.C4 Deep Groove Ball Bearing 17x47x14 mm

FAG 6303ZR.C4 is a deep groove ball bearing with a 17 mm bore, 47 mm outside diameter, and 14 mm width, engineered for smooth rotation and reliable radial-load support in compact applications. The 'ZR' suffix indicates shields on both sides for contaminant protection, while the 'C4' designation specifies higher internal clearance than standard, accommodating thermal expansion and small misalignments during operation. As a standard small- to medium-size bearing in FAG's 6303 series, it provides a robust, general-purpose option suitable for replacing worn units in machinery where space is limited. Its deep-groove geometry enables generous angular misalignment tolerance and consistent load distribution, making it appropriate for moderate radial loads and light axial loads at moderate speeds. This part is intended for use in compatible equipment requiring reliable, long-term rotation with minimal maintenance, offering a precise fit that helps preserve shaft alignment and reduces vibration in everyday mechanical systems.
