W 61803-2RS1 Bearing Product Overview & Core Advantages
The W 61803-2RS1 is a metric single row deep groove ball bearing designed for high-performance applications requiring reliability and precision. Engineered from stainless steel throughout, it offers excellent corrosion resistance. Its key advantage lies in its sealed design (2RS1) which effectively retains lubricant and excludes contaminants, ensuring long service life with minimal maintenance. This bearing is optimized to handle primarily radial loads and is capable of high-speed operation, making it an ideal choice for compact and demanding assemblies.
W 61803-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
- W: Indicates a bearing with a stainless steel construction.
- 61803: The basic bearing series, denoting a deep groove ball bearing with a 17mm bore, 26mm OD, and 5mm width.
- 2RS1: Signifies that the bearing is fitted with two rubber contact seals (RS1), one on each side, providing superior protection.
W 61803-2RS1 Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured entirely from stainless steel, including rings, balls, and cage, this bearing provides high corrosion resistance and durability in harsh environments.
Sealed for Life: The integral rubber contact seals (2RS1) effectively shield the internal components from contaminants like dust and moisture, while also retaining the pre-applied grease lubrication. This creates a maintenance-free solution for the bearing's operational lifespan.
High-Speed Capability: The precision-ground components and optimized internal geometry contribute to a high limiting speed of 16,000 rpm, supporting smooth operation in demanding applications.
Load Handling: With a dynamic load rating of 400 lbf and a static load rating of 286 lbf, it is well-suited to handle significant radial loads in a compact form factor.
W 61803-2RS1 Bearing Typical Application Areas
This bearing's combination of compact size, corrosion resistance, and sealed design makes it suitable for a wide range of applications, including:
- Precision instruments and medical devices
- Food processing and packaging machinery
- Small electric motors and gearboxes
- Office automation equipment (e.g., printers, scanners)
- Various light-duty industrial machinery requiring reliable, maintenance-free operation.
