RLS 20 Bearing Product Overview & Core Advantages
The RLS 20 is a high-precision single row deep groove ball bearing designed for demanding industrial applications requiring exceptional radial load capacity and dimensional stability. Manufactured to P6 tolerance class, this bearing offers superior running accuracy and reliability. Its inch-series design, featuring a 2.5" bore and 5" outside diameter, provides a robust solution for applications where precise shaft fit and high radial dynamic load rating of 13,601 lbf are critical. The open design and absence of seals minimize friction, making it suitable for high-speed operation up to 7,000 rpm.
RLS 20 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| RLS 20 | Basic bearing designation, indicating the series and size. |
| Open (Seal Type) | No contact seals, enabling higher limiting speeds and lower operating temperatures. Requires an external sealing arrangement. |
| P6 (Tolerance Class) | Indicates a precision bearing with tighter dimensional and running accuracy tolerances than standard bearings. |
| CN (Radial Internal Clearance) | Standard (normal) radial internal clearance group. |
| None (Lubrication) | Supplied without lubrication, allowing for application-specific bearing lubrication selection. |
RLS 20 Bearing Structural Features & Performance Benefits
- High-Precision Construction: Built to P6 tolerance class, this bearing ensures minimal runout and vibration, which is essential for high-speed applications and precise machinery.
- Superior Load Capacity: The deep groove raceway and robust chrome steel construction enable it to handle significant radial loads and moderate axial loads in both directions.
- Optimized for High Speed: The stainless steel cage provides high strength and reduced friction at the limiting speed of 7,000 rpm. The open design further enhances heat dissipation.
- Robust Material Selection: Rings and balls made from chrome steel offer high hardness and wear resistance, while the stainless steel cage provides excellent corrosion resistance and durability.
- Wide Temperature Range: Suitable for operating temperatures from -30°C to 120°C, accommodating a broad range of industrial environments.
RLS 20 Bearing Typical Application Areas
This bearing is ideally suited for:
- Electric Motors and Generators
- Industrial Gearboxes and Power Transmission Systems
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Precision Spindles and Machine Tool Accessories
