Product Details, Specifications, and Technical Information

6903-ZZC3 Metric Ball Bearing Key Features 6903-ZZC3 is a Thin High Speed Ball Bearing manufactured with Metal Shields on both sides and is pre-lubricated with Grease, allowing it to be ready for use upon delivery. This Bearing has C3 radial internal clearance for radial slack between the inner and outer rings that is greater than CN (normal) to compensate for thermal expansion. Our Chrome Steel 6900 Series Thin High Speed Light Duty Ball Bearings feature deep groove geometry and minimized inner and outer rings, making this bearing ideal for high speed applications with limited space while still being able to accommodate light radial and axial loads. Applications / Industries 6903-ZZC3 Thin High Speed Light Duty Ball Bearings are used in Aerospace Equipment, Cameras, Optical Equipment, Industrial Robots, Rotary Encoders, Stepping Motors, Laser Engravers, Machining Equipment, Printing Machinery, Factory Automation, among others.
