210 NR Bearing Product Overview & Core Advantages
The 210 NR is a single row deep groove ball bearing designed for outstanding performance in radial load applications. Its key distinguishing feature is the snap ring fitted on the outer ring, which simplifies axial location within a housing, reducing the need for complex and costly housing shoulders. Manufactured to P0 tolerance class with standard CN radial internal clearance, this bearing offers reliable and precise operation. The open design allows for versatile lubrication options, making it suitable for a wide range of industrial machinery where ease of installation and robust radial load capacity are paramount.
Model Code Breakdown
- 210: Basic model number, indicating a metric series deep groove ball bearing with a 50mm bore and 90mm outside diameter.
- NR: Signifies that the bearing is supplied with a snap ring (fitted) in its outer ring groove. This feature aids in axial positioning.
- No Sealing Suffix: The absence of a seal suffix (e.g., 2Z, RS) denotes an open bearing, allowing for custom lubrication schemes.
- No Cage Suffix: The standard cage material is stainless steel, providing good corrosion resistance and durability.
210 NR Bearing Structural Features & Performance Benefits
Snap Ring Groove Design: The integrated snap ring on the outer ring provides a simple and effective method for axial location, reducing assembly costs and complexity by eliminating the need for a shoulder or end cap on one side of the housing.
High Load Capacity: With a dynamic load rating of 8790 lbf and a static load rating of 7756 lbf, this bearing is engineered to handle significant radial loads, ensuring long service life in demanding applications.
Precision & Material Quality: Constructed from chrome steel for both rings and balls, and featuring a stainless steel cage, the bearing offers high strength, wear resistance, and consistent performance under the specified temperature range of -30°C to 120°C.
Versatile Lubrication: The open structure allows the bearing to be lubricated with grease or oil as required by the specific application, providing flexibility for optimal performance and maintenance intervals.
210 NR Bearing Typical Application Areas
The 210 NR bearing is ideally suited for applications requiring secure axial location and high radial load capacity. Common uses include:
- Electric Motors and Gearboxes
- Agricultural Machinery
- Material Handling Equipment (e.g., conveyor rollers)
- Industrial Fans and Blowers
- General machinery where a snap ring simplifies the housing design.
