The 6211-2RS1/C3 is a single-row deep groove ball bearing suitable for various mechanical applications. It features an inner diameter of 55 mm (2.1654 inches), an outer diameter of 100 mm (3.937 inches), and a width of 21 mm (0.8268 inches). The bearing weighs 0.61 kg. It is also known as 6211-2RS1/C3 and is designed with a cylindrical bore (C) and rubber seals on both sides (2RS) to protect against contaminants and retain lubrication. The bearing includes a steel cage (S) for durability and standard performance. This bearing has a C3 internal play, which is higher than the normal radial internal play (Cn), providing a larger clearance range. It is manufactured with standard precision and operates with standard lubrication. The bearing can withstand temperatures up to 120 °C without requiring heat stabilization. There are no external modifications or special treatments applied to this bearing.
