D/W R2-6-2RS1 Bearing Product Overview & Core Advantages
The D/W R2-6-2RS1 is a sealed single row deep groove ball bearing designed for high reliability in compact, precision applications. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its primary advantage is its ability to accommodate significant radial loads while being pre-lubricated and sealed for maintenance-free operation. This makes it an ideal, long-lasting solution for applications demanding compact dimensions and consistent performance.
Model Code Breakdown
- D/W: Manufacturer's prefix (Dunk/Whitney).
- R2-6: Designates the specific bearing size series with a 1/8" bore.
- 2RS1: Indicates the bearing features two (2) contact Rubber Seals (RS) on both sides. The "1" suffix specifies a particular seal design, providing effective protection against contaminants and retaining lubricant.
D/W R2-6-2RS1 Bearing Structural Features & Performance Benefits
Robust Construction: Built entirely from stainless steel (rings, balls, and cage), this bearing ensures high corrosion resistance and durability in harsh environments.
High Load Capacity: With a dynamic load rating of 82 lbf and a static load rating of 26 lbf, it is engineered to handle substantial radial loads for its compact size.
Sealed & Lubricated for Life: The dual-contact 2RS1 seals effectively shield the internals from dust and moisture while retaining the factory-applied grease lubrication. This combination enables maintenance-free operation within the specified temperature range of -30°C to 120°C.
Precision & Speed: Manufactured to P0 tolerance class and CN radial clearance, it ensures smooth and quiet running. The bearing is capable of operating at speeds up to 40,000 rpm.
D/W R2-6-2RS1 Bearing Typical Application Areas
This bearing is ideally suited for a wide range of small, precision machinery and instruments, including:
- Small electric motors and gearboxes
- Medical and dental hand tools
- Precision instruments and optical devices
- Office automation equipment (e.g., printers, scanners)
- Radio control models and drones
- Food processing equipment (benefiting from its stainless steel construction)
