About This Bearing

This product is a **single-row deep groove ball bearing**, the most common type of rolling-element bearing due to its versatility and robust design. The **6318** part number indicates its size, with a 90 mm bore, a 190 mm outer diameter, and a 43 mm width. The **C3** suffix is crucial; it specifies a **radial internal clearance** that is larger than the standard “C0” clearance. This larger clearance is ideal for applications with thermal expansion or interference fits, as it prevents the bearing from seizing under operating conditions. Being an open-type bearing, it does not have seals or shields, making it suitable for applications where the bearing is lubricated by an external system or operates in a clean environment.
