RLS 7-2Z Bearing Product Overview & Core Advantages
The RLS 7-2Z is a single row deep groove ball bearing designed for high-performance applications requiring precision and reliability. Engineered to primarily handle radial loads, its inch-series dimensions and shielded construction make it an ideal choice for compact assemblies. This bearing features a P6 tolerance class for superior running accuracy and is pre-lubricated with grease, ensuring immediate operation and long service life in a wide temperature range from -30°C to 120°C.
RLS 7-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| 7 | Series designation indicating specific boundary dimensions. | Ensures dimensional compatibility and interchangeability. |
| 2Z | Bearing is equipped with shields on both sides. | Provides effective protection against contamination while being suitable for high-speed operation (up to 13,000 rpm). |
RLS 7-2Z Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to a P6 tolerance class with tight dimensional control on the bore, outside diameter, and width. This results in precise shaft positioning, reduced vibration, and consistent performance under load.
- Robust Load Capacity: With a dynamic load rating of 3147 lbf and a static load rating of 1720 lbf, this bearing is engineered to handle significant radial loads in demanding applications.
- Optimized for Speed and Longevity: The combination of a stainless steel cage, shielded design (2Z), and pre-applied grease enables a high limiting speed of 13,000 rpm. The standard CN radial internal clearance is suitable for most operating conditions.
- Low Maintenance & Corrosion Resistance: The non-removable shields retain the lubricant and effectively exclude contaminants. The use of chrome steel for rings and balls, combined with a stainless steel cage, offers excellent resistance to corrosion and ensures reliable, long-term operation.
RLS 7-2Z Bearing Typical Application Areas
This versatile precision bearing is commonly specified in:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
- Precision Agricultural Machinery
- Various OEM applications requiring reliable, high-speed inch-sized bearings.
