S687zz Bearing Product Overview & Core Advantages
The S687zz is a single row deep groove ball bearing engineered for high-speed operation and reliable performance in demanding applications. Constructed entirely from stainless steel, including its rings, balls, and cage, it offers excellent corrosion resistance. Its shielded design effectively retains lubricant and excludes contaminants, ensuring long service life. This bearing is designed to primarily handle radial loads and is characterized by its compact dimensions (7mm bore, 14mm OD, 5mm width), making it an ideal choice for applications where space is limited and precision is required.

| S | Stainless Steel Construction | Provides superior corrosion resistance for use in harsh environments. |
| zz | Shielded on Both Sides | Protects the bearing interior from contaminants and helps retain lubrication, enhancing reliability and service life. |
S687zz Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & High-Quality Balls: The geometry of the deep groove raceway, combined with 9 precision stainless steel balls, allows for smooth operation and efficient handling of radial loads.
- Stainless Steel Cage: The integrated cage ensures proper ball spacing and guidance, contributing to stable performance and low vibration at the limiting speed of 36,000 rpm.
- Shielded Protection: The non-contact stainless steel shields are a key feature for maintenance-friendly operation, protecting against particulate contamination without significantly increasing friction.
- Precision Tolerance: Manufactured to ABEC1 tolerance class and featuring MC3 radial internal clearance (0.002mm to 0.013mm), this bearing delivers consistent and precise rotational accuracy.
