W 6203-2RS1/W64 Bearing Product Overview & Core Advantages
The W 6203-2RS1/W64 is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Engineered with stainless steel rings and balls, it offers superior corrosion resistance. Its key advantages include the ability to handle radial loads efficiently, a sealed design for contamination protection, and solid oil lubrication for maintenance-free operation over a wide temperature range from -30°C to 120°C. This combination makes it a compact, reliable, and long-lasting solution for precision machinery.
W 6203-2RS1/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Benefit |
|---|---|---|
| 2RS1 | Contact seals on both sides made of NBR | Provides excellent protection against contaminants and retains lubricant effectively. |
| W64 | Solid oil lubrication | Ensures maintenance-free operation, eliminates lubricant leakage, and is suitable for a wide temperature range. |
W 6203-2RS1/W64 Bearing Structural Features & Performance Benefits
- Corrosion Resistance: Constructed entirely from stainless steel (rings and balls), this bearing is ideal for applications exposed to moisture, chemicals, or washdown environments.
- Sealed & Lubricated for Life: The combination of 2RS1 contact seals and W64 solid oil creates a sealed, maintenance-free unit. This prevents lubricant washout and ingress of contaminants, significantly extending bearing service life.
- Precision & Load Capacity: Manufactured to ABEC 1 | ISO P0 tolerance class with CN radial internal clearance, it ensures smooth, quiet, and reliable operation. It is rated for a dynamic load capacity of 1812 lbf and a static load capacity of 1068 lbf.
- High-Speed Capability: With a limiting speed of 26,000 rpm, it is suitable for high-speed applications requiring reliable performance.
W 6203-2RS1/W64 Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Food & Beverage Processing Equipment (conveyors, mixers)
- Medical and Laboratory Devices
- Chemical Handling Pumps and Mixers
- Marine and Outdoor Equipment
- Electric Motors and Gearboxes in corrosive environments
