6214 NR Bearing Product Overview & Core Advantages
The 6214 NR is a single row deep groove ball bearing designed for exceptional radial load capacity and reliable performance in demanding industrial applications. Its key distinguishing feature is the snap ring groove and fitted snap ring on the outer ring, which provides axial location and simplifies housing design by eliminating the need for complex end covers or shoulders. Manufactured with chrome steel rings and balls, and a stainless steel cage, this bearing offers high durability and consistent operation within a wide temperature range. Its open design allows for versatile lubrication options, making it suitable for various operating conditions.

| Code Segment | Technical Meaning |
|---|---|
| 6214 | Standard bearing series designation indicating a single row deep groove ball bearing with a 70 mm bore, 125 mm OD, and 24 mm width. |
| NR | Indicates the outer ring has a snap ring groove and is supplied with a fitted snap ring for axial location. |
6214 NR Bearing Structural Features & Performance Benefits
- Snap Ring Location: The integrated snap ring groove and supplied snap ring enable secure axial positioning within the housing, reducing assembly complexity and cost. The outer ring snap ring diameter is 134.7 mm with a width of 2.82 mm.
- High Load Capacity: Engineered with a radial dynamic load rating of 14,320 lbf and a radial static load rating of 10,116 lbf, this bearing reliably handles significant radial loads in continuous operation.
- Optimized for Speed: The stainless steel cage ensures stability and low friction, contributing to a high limiting speed of 7,000 rpm.
- Precision & Durability: Manufactured to P0 tolerance class with a standard CN radial internal clearance, it provides consistent performance and interchangeability. The use of high-grade chrome steel components ensures long service life and resistance to wear.
- Versatile Lubrication: The open seal type allows for the application of various lubricants (grease or oil) tailored to specific speed, temperature, and environmental conditions.
6214 NR Bearing Typical Application Areas
