W 608 R-2Z Bearing Product Overview & Core Advantages
The W 608 R-2Z is a single row deep groove ball bearing designed for exceptional performance in compact spaces. Engineered with stainless steel construction throughout, it offers superior corrosion resistance. Its key advantage lies in its ability to handle radial loads efficiently while featuring shielded (2Z) seals that retain lubrication and exclude contaminants, ensuring long service life and reduced maintenance. This bearing is an ideal choice for applications demanding high reliability, smooth operation, and a compact bearing size.
Model Code Breakdown
| Prefix/Suffix | Meaning | Technical Implication |
|---|---|---|
| W | Stainless Steel Bearing | Indicates the rings, balls, and cage are made from stainless steel, providing excellent corrosion resistance. |
| 608 | Bore Size Code | Standard designation for a bearing with an 8 mm bore diameter, 22 mm outside diameter, and 7 mm width. |
| R | Flanged Outer Ring | The outer ring includes an integral flange (25 mm diameter), simplifying mounting and axial location. |
| 2Z | Shielded on Both Sides | Non-contact steel shields protect the bearing interior from contamination while retaining the pre-applied grease. |
W 608 R-2Z Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: All critical components (rings, balls, cage) are manufactured from stainless steel, ensuring high corrosion resistance and suitability for harsh environments, including washdown applications.
- Flanged Design for Easy Installation: The flanged outer ring (R suffix) allows for simplified and secure axial positioning within a housing, reducing assembly time and cost.
- Effective Sealing with Shields: The 2Z shields are a key feature, providing effective protection against dust and other particulates. This helps to retain the factory-applied grease lubrication, contributing to a maintenance-free or long-interval service life.
- Optimized for Radial Loads: The deep groove raceway and single row design are optimized to carry significant radial dynamic and static load ratings (447 lbf and 175 lbf respectively) within its compact dimensions.
- Standard Precision & Clearance: Manufactured to P0 tolerance class and CN radial internal clearance, this bearing offers reliable and consistent performance for a wide range of general-purpose applications.
W 608 R-2Z Bearing Typical Application Areas
The W 608 R-2Z is widely used in applications requiring a compact, corrosion-resistant, and reliable bearing solution. Common industries and equipment include:
- Food & Beverage Processing Equipment (conveyors, mixers)
- Medical and Laboratory Devices
- Small Electric Motors and Precision Instruments
- Office Automation Equipment (printers, scanners)
- Various Light-Duty Industrial Machinery where space is limited and environmental resistance is needed.
