6205-RS2ZNBR/C3

• 6205: Basic designation indicating a single row deep groove ball bearing with a 25 mm bore and 52 mm outside diameter.
• RS2Z: Denotes the sealing type. RS indicates a contact seal (rubber seal) on one side, and 2Z indicates non-contact metal shields (ZZ) on both sides. This combination offers superior protection against contamination.
• NBR: Signifies a snap ring groove on the outer ring. This feature allows for simplified axial location and secure mounting within a housing, reducing the need for complex housing designs.
• C3: Specifies a greater than normal radial internal clearance. This is ideal for applications with high-temperature gradients or where interference fits are used, preventing excessive preload and potential bearing failure.

The single row deep groove ball bearing design provides a versatile solution for a wide range of applications. The shielded construction (RS2Z) effectively retains lubricant and excludes contaminants, significantly enhancing bearing life and enabling maintenance-free operation in many environments. The snap ring groove (NBR) on the outer ring contributes to efficient assembly and secure positioning, increasing the overall rigidity of the mounted arrangement. The specified C3 radial clearance ensures stable performance under operational heat and press-fits, preventing binding and maintaining smooth rotation. With a radial dynamic load rating of 3147 lbf and a limiting speed of 13,000 rpm, this bearing offers a reliable balance of load capacity and speed capability.

This bearing is well-suited for various industrial machinery and equipment, including:

• Electric Motors and Gearboxes
• Industrial Pumps and Compressors
• Material Handling Conveyors
• Agricultural Machinery
• Automotive Components (e.g., alternators, idlers)

Its snap ring feature makes it particularly valuable in applications where housing design simplification and secure axial location are critical.
