S63801zz Bearing Product Overview & Core Advantages
The S63801zz is a miniature deep groove ball bearing designed for precision applications requiring compact dimensions and reliable performance. This single row bearing excels in handling primarily radial loads and is constructed entirely from stainless steel for enhanced corrosion resistance. Its shielded design offers protection from contamination while maintaining low friction, making it a robust and durable solution for high-speed, high-precision environments where space is at a premium.
S63801zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix / Prefix | Technical Meaning |
|---|---|
| S | Stainless Steel construction for the bearing rings and balls. |
| 63 | Series designation indicating a deep groove design with specific dimensional proportions. |
| 8 | Bore diameter code corresponding to a 12 mm bore. |
| 01 | Outside diameter and width code for the 21 mm x 7 mm dimensions. |
| zz | Indicates the bearing is shielded on both sides (2Z). This provides effective protection against contaminants while allowing for high-speed operation. |
S63801zz Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With dimensions of 12 mm x 21 mm x 7 mm and a weight of only 8.5 g, this bearing is ideal for applications with severe space and weight constraints.
- Corrosion Resistance: Manufactured entirely from stainless steel, the bearing offers excellent resistance to rust and corrosion, suitable for use in harsh environments and ensuring a long service life.
- High-Speed Capability: The combination of a deep groove raceway, stainless steel cage, and shielded design enables a high limiting speed of 32,400 rpm, making it a capable high-speed bearing.
- Precision Performance: Built to ABEC-1 tolerance class with a controlled C0 radial internal clearance (0.003mm to 0.018mm), it delivers consistent and smooth operation for precision mechanisms.
- Shielded Protection: The non-contact ZZ shields retain lubrication and protect the internal components from dust and other particulates, enhancing reliability and reducing maintenance needs.
S63801zz Bearing Typical Application Areas
This bearing is commonly specified in:
- Precision Instruments: Optical encoders, medical devices, and laboratory equipment.
- Small Motors: Stepper motors, servo motors, and miniature DC motors.
- Office Automation: Printers, scanners, and copiers.
- Robotics: Small joints, actuators, and drone gimbals.
- Consumer Electronics: High-speed spindles in small fans and disc drives.
