| W | Stainless Steel Bearing |
| 61803 | Series designation for a deep groove ball bearing with a 17 mm bore, 26 mm OD, and 5 mm width. |
| -2RS1 | Contact seals on both sides, providing effective protection against contaminants and retaining lubricant. |
| /VT378 | Designates a specific, high-performance grease filling suitable for the specified temperature range. |
W 61803-2RS1/VT378 Bearing Structural Features & Performance Benefits
- Robust Construction & Corrosion Resistance: The use of stainless steel for both rings and balls ensures superior resistance to rust and corrosion, making it ideal for harsh environments and washdown applications.
- Effective Sealing: The 2RS1 contact seals effectively shield the internal components from dust, moisture, and other contaminants, while also retaining the lubricant for extended service life.
- High-Speed Capability: With a limiting speed of 16,000 rpm, this bearing is engineered for high-speed operation, supported by its precision construction and effective sealing.
- Precision & Load Capacity: Manufactured to ABEC 1 precision tolerances, it ensures smooth and quiet operation. The radial dynamic load rating of 400 lbf demonstrates its capability to handle substantial radial forces in a compact bearing size.
- Maintenance-Free Operation: The combination of integral seals and a factory-applied, high-temperature grease (VT378) provides a long, maintenance-free service interval under normal operating conditions.
W 61803-2RS1/VT378 Bearing Typical Application Areas
