S6908zz Bearing Product Overview & Core Advantages
The 6908zz stainless steel deep groove ball bearing represents a precision bearing solution engineered for demanding applications. As a single row, shielded metric bearing, it is designed to primarily accommodate radial loads with high reliability. Constructed entirely from corrosion-resistant stainless steel, including the rings, balls, and cage, it offers exceptional performance in harsh environments. Its compact design, with a 40 mm bore and 62 mm outside diameter, provides a robust and space-efficient component for machinery requiring long service life and consistent operation within a wide temperature range.
S6908zz Bearing Model Code Explained, Specifications & Naming Convention
The model number 6908zz provides specific technical information:
- 6908: Denotes the bearing series and size. The '69' series indicates a deep groove ball bearing with a specific dimensional relationship. The '08' corresponds to a bore diameter of 40 mm (08 x 5 = 40 mm).
- zz (or 2Z): This suffix signifies that the bearing is equipped with shielded seals on both sides. These non-contact metal shields protect the bearing interior from large contaminants while minimizing friction, contributing to the bearing's limiting speed of 9,900 rpm.
S6908zz Bearing Structural Features & Performance Benefits
- Full Stainless Steel Construction: The use of stainless steel for all critical components (rings, balls, cage) provides superior corrosion resistance, making it ideal for applications exposed to moisture, chemicals, or washdowns. This ensures dimensional stability and longevity.
- Optimized Load Capacity: With a dynamic load rating of 2772 lbf and a static load rating of 2007 lbf, this bearing is designed to handle significant radial loads, offering reliable performance under stress.
- High-Speed Capability: The combination of a stainless steel cage, low-friction shields (zz), and precision ABEC-1 tolerances enables a high limiting speed of 9,900 rpm, suitable for various high-speed machinery.
- Precision & Consistency: Manufactured to ABEC-1 precision class standards with a C0 radial internal clearance (0.006mm to 0.020mm), this bearing ensures smooth and quiet operation, reducing vibration and noise in sensitive applications.
S6908zz Bearing Typical Application Areas
This versatile bearing is commonly specified in industries and equipment where corrosion resistance, reliability, and high-speed performance are critical. Key applications include:
- Food and Beverage Processing Equipment (conveyors, mixers)
- Medical and Laboratory Devices
- Chemical Handling Pumps and Mixers
- Marine and Outdoor Equipment
- Precision Electric Motors and Gearboxes
