6812zz Bearing Product Overview & Core Advantages
The 6812zz bearing is a metric single row deep groove ball bearing designed for reliable performance in demanding applications. Its shielded construction (ZZ) provides effective protection against contaminant ingress while maintaining low friction operation. Engineered with ABEC-1 precision tolerance and C0 radial internal clearance, this bearing delivers consistent performance and long service life. The combination of chrome steel rings and balls with a stainless steel cage ensures excellent durability and corrosion resistance, making it suitable for various industrial applications requiring radial load capacity and moderate speed operation.
Model Code Detailed Explanation
| Code Segment | Technical Meaning |
|---|---|
| 68 | Extra light series bearing with optimized cross-section |
| 12 | Bore diameter: 60 mm (12 × 5 = 60 mm) |
| ZZ | Double shielded design providing protection from both sides |
6812zz Bearing Structural Features & Performance Benefits
Optimized Load Distribution: The single row deep groove raceway design enables efficient handling of radial loads while accommodating moderate axial loads in both directions. With a radial dynamic load rating of 2588 lbf and static load rating of 2385 lbf, this bearing provides reliable performance under various operating conditions.
Precision Engineering: Manufactured to ABEC-1 tolerance class with bore diameter tolerance of -0.015mm to 0 and outside diameter tolerance of -0.013mm to 0, ensuring consistent fit and performance. The C0 radial clearance (0.008mm to 0.028mm) provides optimal operation for most industrial applications.
Enhanced Protection & Durability: The double shielded (ZZ) design effectively retains lubrication and excludes contaminants, while the stainless steel cage provides excellent corrosion resistance and cage stability at the limiting speed of 9,400 rpm.
Material Excellence: Constructed from chrome steel rings and balls for high load capacity and wear resistance, complemented by a stainless steel cage that withstands harsh operating environments within the temperature range of -30°C to 110°C.
