W 61902-2RS1 Bearing Product Overview & Core Advantages
The W 61902-2RS1 is a metric single row deep groove ball bearing designed for high performance in compact spaces. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its sealed design (2RS1) and pre-lubrication, making it a maintenance-free solution ideal for applications requiring protection from contaminants. This bearing is engineered to handle primarily radial loads efficiently and is capable of high-speed operation, making it a reliable choice for precision equipment.
Model Code Breakdown
- W: Indicates a stainless steel construction for the bearing rings and balls.
- 61: Signifies the bearing series, denoting a deep groove design with a specific cross-section.
- 9: Denotes a flanged outer ring, providing axial location and simplified mounting.
- 02: Specifies the bore diameter code, corresponding to a 15 mm bore.
- 2RS1: Indicates the bearing is fitted with two rubber seals (RS1) on both sides, offering effective protection against dust and moisture, and retaining the lubricant.
W 61902-2RS1 Bearing Structural Features & Performance Benefits
Robust Stainless Steel Construction: All components, including rings, balls, and the cage, are made from stainless steel, providing superior corrosion resistance and durability in harsh environments.
Effective Sealing: The 2RS1 contact rubber seals effectively shield the internal components from contaminants and prevent lubricant leakage, ensuring long-term reliability and enabling maintenance-free operation.
High-Speed Capability: The precision deep groove geometry and optimized grease lubrication contribute to a high limiting speed of 16,000 rpm, suitable for demanding applications.
Radial Load Capacity: The single row deep groove raceway is designed to carry significant radial dynamic and static loads (834 lbf / 504 lbf), providing stable performance.
Simplified Mounting: The integral flanged outer ring facilitates easy axial location and installation, reducing assembly time and complexity.
W 61902-2RS1 Bearing Typical Application Areas
