SF63803ZZ Bearing Product Overview & Core Advantages
The SF63803ZZ is a metric flanged ball bearing designed for precision applications requiring compact design and reliable performance. This single row bearing features shielded construction and is engineered to handle primarily radial loads while providing excellent operational stability. Manufactured with stainless steel rings and chrome steel balls, it offers superior corrosion resistance and durability. With its integrated flange for secure mounting and ABEC-1 precision class, this bearing delivers consistent performance in demanding environments where space constraints and reliability are critical factors.
SF63803ZZ Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| SF63803 | Basic bearing designation with 17mm bore diameter | Standardized sizing for easy replacement and integration |
| ZZ | Double shielded construction on both sides | Enhanced contamination protection and extended service life |
SF63803ZZ Bearing Structural Features & Performance Benefits
Flanged Design: The integrated flange (28mm outer diameter, 1.5mm thickness) provides secure mounting and precise positioning, eliminating the need for additional housing components and reducing assembly complexity.
Shielded Protection: Double stainless steel shields (300 series) effectively prevent contaminant ingress while maintaining low friction operation, contributing to the bearing's 21,600 rpm limiting speed capability.
Precision Engineering: With ABEC-1 tolerance class and controlled radial internal clearance (C0), this bearing ensures smooth operation and minimal vibration. The stainless steel cage maintains proper ball spacing for consistent load distribution.
Load Capacity: Rated for 451 lbf dynamic and 295 lbf static radial loads, the bearing features 16 precision balls (2.381mm diameter) that optimize stress distribution and enhance fatigue life.
