D/W R4-2RS1 Bearing Product Overview & Core Advantages
The R4-2RS1 is a single row deep groove ball bearing designed for high precision and reliability in demanding applications. This inch-series bearing excels at handling primarily radial loads and is constructed entirely from stainless steel for superior corrosion resistance. Its compact design, combined with integrated seals and pre-applied grease lubrication, makes it an ideal, maintenance-free solution for applications requiring long service life and consistent performance.
D/W R4-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code | Description | Technical Significance |
|---|---|---|
| R4 | Bearing Series & Bore Size | Denotes the inch-series bearing with a 1/4" (0.25") bore diameter. |
| 2RS1 | Sealing | Indicates the bearing is fitted with contact seals on both sides. This provides excellent protection against contaminants and retains lubricant effectively. |
D/W R4-2RS1 Bearing Structural Features & Performance Benefits
- Superior Sealing & Contamination Resistance: The 2RS1 double-contact seals effectively shield the internal components from dust, moisture, and other contaminants, significantly extending bearing life in harsh environments.
- Corrosion-Resistant Construction: Manufactured entirely from stainless steel (rings, balls, and cage), this bearing is ideal for applications exposed to moisture, chemicals, or washdowns, ensuring long-term reliability.
- Ready-to-Install & Maintenance-Free: Pre-lubricated with grease, the bearing is ready for immediate use and requires no additional maintenance, reducing downtime and total cost of ownership.
- Precision Performance: Built to P0 tolerance class and standard CN radial internal clearance, it offers smooth and quiet operation, making it suitable for precision instruments and equipment.
D/W R4-2RS1 Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Food & Beverage Processing Equipment (for corrosion resistance and washdown capability)
- Medical and Laboratory Devices (for precision and clean operation)
- Small Electric Motors and Gearboxes
- Precision Instrumentation and Optical Devices
- Agricultural and Marine Equipment (where environmental sealing is critical)
