RMS 11 Bearing Product Overview & Core Advantages
The RMS 11 is a single row deep groove ball bearing designed for high-precision applications requiring reliable radial load capacity. Manufactured to P6 tolerance class, it offers superior dimensional accuracy and running precision. Its open design and optimized internal geometry contribute to a high limiting speed of 15,000 rpm, making it an excellent choice for demanding industrial environments. The bearing is constructed entirely from high-grade materials, including chrome steel rings and balls with a stainless steel cage, ensuring durability and long service life.
RMS 11 Bearing Model Code Explained, Specifications & Naming Convention

| Open (from spec) | Seal Type | No seals or shields, allowing for higher speeds and easy re-lubrication in service. |
| P6 (from spec) | Tolerance Class | Indicates tighter dimensional and running accuracy than standard bearings. |
| CN (from spec) | Radial Internal Clearance | Standard radial internal clearance for normal operating conditions. |
RMS 11 Bearing Structural Features & Performance Benefits
High-Precision Design: The single row construction with a deep groove raceway is engineered for excellent radial load handling. The P6 tolerance class ensures minimal runout and vibration, which is critical for smooth operation.
Robust Load Capacity: With a dynamic load rating of 9217 lbf and a static load rating of 5395 lbf, this bearing provides reliable performance under significant stress.
Optimized for High-Speed Operation: The combination of the stainless steel cage and the open, low-friction design enables a high limiting speed, making it suitable for high-speed spindles and motors.
Durable Material Construction: The use of chrome steel for rings and balls provides high hardness and wear resistance, while the stainless steel cage offers corrosion resistance and strength.
RMS 11 Bearing Typical Application Areas
- Electric Motors and Generators: Ideal for supporting shafts in high-RPM applications.
- Industrial Pumps and Compressors: Handles radial loads efficiently in fluid handling equipment.
- Precision Machinery and Spindles: The P6 precision and high-speed capability make it suitable for machine tool applications.
- Material Handling Equipment: Provides reliable performance in conveyors and other heavy-duty systems.
