W 6009-2RS1/VT378 Bearing Product Overview & Core Advantages
The W 6009-2RS1/VT378 is a metric single row deep groove ball bearing designed for exceptional reliability in demanding applications. Constructed entirely from stainless steel (rings and balls) and featuring integral seals (2RS1), it offers superior corrosion resistance and protection against contaminant ingress. Its core advantages include high operational integrity due to its ABEC 1 (ISO P0) precision class, making it suitable for applications requiring consistent performance under radial loads. The pre-lubrication with VT378 grease ensures immediate operation and long-term performance across a wide temperature range from -30°C to 120°C.
W 6009-2RS1/VT378 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| W | Stainless Steel Bearing | Indicates the bearing is manufactured from stainless steel, providing excellent corrosion resistance. |
| 6009 | Basic Bearing Number | Denotes a single row deep groove ball bearing with a 45 mm bore, 75 mm OD, and 16 mm width. |
| 2RS1 | Contact Seals on Both Sides | Features low-friction nitrile rubber (NBR) seals that effectively retain lubricant and exclude contaminants, enhancing bearing life. |
| VT378 | Food-Grade Grease | Specifies a high-quality, food-grade lubricant suitable for the specified temperature range, making the bearing ready-to-mount and maintenance-free. |
W 6009-2RS1/VT378 Bearing Structural Features & Performance Benefits
The design of the W 6009-2RS1/VT378 translates directly into key performance benefits for engineers. The deep groove raceway and single row construction are optimized to handle significant radial dynamic and static loads (4092 lbf and 3372 lbf respectively). The use of a chrome steel cage ensures stability and guides the balls effectively, contributing to smooth operation. The combination of stainless steel components and effective sealing provides outstanding durability in humid or corrosive environments. With a standard CN radial internal clearance and ABEC 1 precision, it delivers reliable, low-noise, and low-vibration performance, supporting a limiting speed of 12,000 rpm for various applications.
W 6009-2RS1/VT378 Bearing Typical Application Areas
