SF63801ZZ Bearing Product Overview & Core Advantages
The SF63801ZZ is a metric flanged ball bearing engineered for precision and reliability in compact applications. As a single row deep groove ball bearing with an integral flange, it offers simplified mounting and precise axial location. Its stainless steel construction provides excellent corrosion resistance, making it suitable for demanding environments. The bearing is designed to primarily handle radial loads with high efficiency. The inclusion of shields (ZZ) helps protect against contamination, contributing to a longer service life and consistent performance in applications requiring ABEC-1 precision.
SF63801ZZ Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF63801 | Basic bearing designation, indicating a flanged design with a 12 mm bore diameter. |
| ZZ | Signifies the bearing is equipped with non-contact shields on both sides. This provides effective protection against solid contaminants while minimizing friction. |
SF63801ZZ Bearing Structural Features & Performance Benefits
- Flanged Design & High Rigidity: The integral flange simplifies assembly and provides secure axial positioning, enhancing the overall rigidity of the mounting arrangement.
- Radial Load Capacity: The deep groove raceway and optimized internal geometry are designed to efficiently support significant radial dynamic and static loads (388 lbf and 210 lbf respectively).
- Precision & Speed: Manufactured to ABEC-1 tolerance class with a standard C0 radial clearance, this bearing ensures smooth operation and is capable of operating at a limiting speed of 27,000 rpm.
- Durable Construction: The use of stainless steel for the rings, cage, and shields offers excellent resistance to corrosion and is suitable for a wide temperature range from -30°C to 110°C.
- Contamination Protection: The shielded (ZZ) design helps retain lubrication and exclude debris, contributing to reliable, long-term performance. Lubrication is required for optimal operation.
SF63801ZZ Bearing Typical Application Areas
This flanged miniature bearing is ideal for applications requiring compact size, precise location, and reliable performance. Common uses include:
- Small precision motors and stepper motors
- Medical and dental handpieces
- Office automation equipment (printers, scanners)
- Robotics and miniature gearboxes
- Instrumentation and control devices
