The 6211 deep groove ball bearing is a standard open-type bearing designed for industrial applications that require high load capacity, smooth operation, and efficient lubrication. As a single-row deep groove ball bearing without seals or shields, this bearing is ideal for applications where regular lubrication is available and higher operating efficiency is required.
The 6211 bearing is engineered to handle high radial loads together with moderate axial loads in both directions, making it a versatile and reliable solution for a wide range of industrial machinery and mechanical systems.
Precision Engineering and Open Bearing Design
The 6211 bearing is manufactured with precision-ground inner and outer rings and high-quality steel balls to ensure smooth rotation, low friction, and reduced vibration. Its deep groove raceway geometry allows optimal load distribution across the rolling elements, minimizing internal stress, wear, and heat generation during operation.
As an open bearing design, the 6211 allows direct access to lubrication, which makes it suitable for systems with oil circulation or frequent relubrication. This design supports efficient heat dissipation and stable performance in applications operating under continuous or heavy-duty conditions.
Technical Specifications of 6211 Ball Bearing
The 6211 deep groove ball bearing has an inner diameter of 55 mm, an outer diameter of 100 mm, and a width of 21 mm. With an approximate weight of 0.60 kg, the bearing offers a robust and durable construction suitable for medium to heavy-duty industrial applications.
In terms of load capacity, the bearing provides a dynamic load rating of 44.4 kN and a static load rating of 29.1 kN, enabling it to operate reliably under substantial radial loads while maintaining stable axial load support.
Regarding speed capability, the 6211 bearing can operate at speeds of up to 6,400 revolutions per minute when grease-lubricated and up to 7,600 revolutions per minute when oil-lubricated. The open design allows efficient lubrication and heat dissipation, contributing to stable performance under demanding operating conditions.
