W 6204-2RS1/VP311 Bearing Product Overview & Core Advantages
The W 6204-2RS1/VP311 is a single row deep groove ball bearing designed for high reliability and long service life in demanding applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantages include the ability to handle significant radial loads and moderate axial loads in both directions. The integrated sealed design and pre-applied grease ensure maintenance-free operation, making it an ideal choice for applications requiring high precision and operational reliability in challenging environments.
W 6204-2RS1/VP311 Bearing Model Code Explained, Specifications & Naming Convention
The model number W 6204-2RS1/VP311 is decoded as follows:
- W: Indicates a bearing with a stainless steel design.
- 62: Denotes the deep groove ball bearing series.
- 04: Specifies the bore diameter; 04 corresponds to a 20 mm bore (04 x 5 = 20 mm).
- 2RS1: Signifies that the bearing is fitted with two contact seals (RS) on both sides, providing effective protection against contamination and grease leakage.
- VP311: Refers to the specific grease filling used, optimized for the bearing's operational temperature range and speed.
W 6204-2RS1/VP311 Bearing Structural Features & Performance Benefits
- Robust Construction & Corrosion Resistance: Manufactured from stainless steel rings, balls, and cage, this bearing is inherently resistant to rust and corrosion, ensuring performance in humid or chemically aggressive environments.
- High Load Capacity: The deep groove raceway and optimized internal geometry enable it to carry a substantial radial dynamic load rating of 2428 lbf and a static load rating of 1472 lbf, while also accommodating bidirectional axial loads.
- Sealed & Lubricated for Life: The 2RS1 contact seals effectively shield the internal components from contaminants and retain the pre-applied grease. This combination allows for maintenance-free operation and a long service life, eliminating the need for re-lubrication.
- Precision & Speed: Built to P0 tolerance class and standard CN radial internal clearance, it offers reliable and consistent performance. The design supports a limiting speed of 10,000 rpm, making it suitable for a wide range of operational speeds.
W 6204-2RS1/VP311 Bearing Typical Application Areas
This versatile bearing is commonly specified in industries and equipment where corrosion resistance, reliability, and minimal maintenance are critical. Typical applications include:
- Food and Beverage Processing Machinery
- Medical and Laboratory Equipment
- Chemical and Pharmaceutical Processing Pumps
- Agricultural Machinery
- Marine and Submerged Applications
