6011-2ZNRJEM

• 6011: Basic designation indicating a single row deep groove ball bearing with a 55 mm bore and 90 mm outside diameter.
• 2Z: Signifies that the bearing is shielded on both sides. This provides effective protection against contaminant ingress while allowing for high-speed operation compared to contact seals.
• NR: Denotes a snap ring groove on the outer ring. This feature allows for simplified axial location and secure fitting within a housing, reducing the need for complex housing designs.
• JEM: This suffix combination is specific to the manufacturer and may refer to internal design optimizations or material selections. In this context, it confirms the use of chrome steel for rings, balls, and cage.

Robust Construction for Radial Loads: The single row deep groove raceway and chrome steel construction are engineered to handle the specified radial dynamic load rating of 6362 lbf effectively, providing reliable performance under stress.

Simplified Assembly with Snap Ring: The integrated snap ring groove (NR) on the outer ring enhances design flexibility. It simplifies axial positioning and securing of the bearing within the housing, contributing to easier maintenance and assembly.

Contamination Protection & Speed Capability: The non-contact shields (2Z) protect the internal components from large particulate contaminants without generating significant friction, supporting the bearing's limiting speed of 7,500 rpm.

Standardized Precision: Manufactured to ABEC 1 | ISO P0 tolerance class with a standard CN radial internal clearance, this bearing offers a cost-effective solution for applications requiring dependable, general-purpose precision.

The 6011-2ZNRJEM is ideally suited for a wide range of industrial machinery and equipment where reliable radial load support and simplified mounting are key. Common applications include:

• Electric Motors and Generators
• Gearboxes and Transmission Systems
• Industrial Fans and Blowers
• Material Handling Conveyors
• Agricultural Machinery
