W 61809 Bearing Product Overview & Core Advantages
The W 61809 is a single row deep groove ball bearing designed for high-performance applications requiring precision and reliability. This metric bearing excels in handling primarily radial loads and is characterized by its compact cross-section with a 7 mm width. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. With a P0 tolerance class and standard CN radial internal clearance, it provides consistent performance for general applications. Its open design allows for versatile lubrication options, making it a robust and adaptable component for various machinery.
W 61809 Bearing Model Code Explained, Specifications & Naming Convention
The model number W 61809 can be broken down as follows to understand its technical specifications:
- W: Designates a series of stainless steel deep groove ball bearings.
- 61: Indicates a deep groove design with a particularly thin cross-section.
- 809: Specifies the bore diameter. The last two digits multiplied by 5 give the bore in mm (09 * 5 = 45 mm).
Key Feature Absence: The lack of additional suffixes (e.g., -2Z, -RS) confirms this is an open bearing without seals or shields, offering maximum flexibility for custom lubrication schemes.
W 61809 Bearing Structural Features & Performance Benefits
The design of the W 61809 translates into distinct performance advantages:
- Compact & Lightweight Design: With a width of just 7 mm and a weight of 0.034 kg, this bearing is ideal for applications where space and weight savings are critical.
- High Corrosion Resistance: Constructed entirely from stainless steel (rings, balls, and cage), it is suitable for use in harsh environments, including those exposed to moisture or certain chemicals.
- Precision Performance: The P0 tolerance class ensures dimensional accuracy and running precision for reliable operation in a wide range of equipment.
- Versatile Lubrication: The open seal type allows engineers to select the optimal grease or oil lubrication based on specific speed, temperature, and life requirements.
