FR133zz Bearing Product Overview & Core Advantages
The FR133zz is a miniature shielded ball bearing designed for precision applications requiring compact dimensions and reliable performance. This single row radial ball bearing features a shielded design for contaminant protection and is constructed from high-grade chrome steel for durability. Its primary advantages include a compact design for space-constrained assemblies, a high limiting speed of 80,000 rpm for dynamic operations, and compliance with RoHS and REACH environmental standards, making it suitable for modern, sensitive applications.
FR133zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| FR133 | Denotes the specific bearing series and size designation. |
| zz | Indicates that the bearing is equipped with shields on both sides. This provides effective protection against dust and other contaminants while minimizing friction compared to contact seals. |
FR133zz Bearing Structural Features & Performance Benefits
- Robust Construction: The combination of chrome steel rings and balls, along with a stainless steel cage, provides excellent wear resistance and mechanical strength, ensuring a long service life.
- High-Speed Capability: The stainless steel cage and optimized internal geometry contribute to stable operation at the high limiting speed of 80,000 rpm, making it an excellent high-speed bearing for demanding applications.
- Contaminant Protection: The non-contact stainless steel shields (zz) help retain lubrication and exclude large particulate contaminants, enhancing reliability in unclean environments.
- Precision & Clearance: Manufactured to ABEC1 tolerance class with an MC3 radial internal clearance (0.00008" to 0.0005"), ensuring smooth and precise rotation with minimal vibration.
FR133zz Bearing Typical Application Areas
This bearing is ideally suited for a wide range of small precision machinery and devices, including:
- Small DC motors and stepper motors
- Precision instruments and optical encoders
- Computer cooling fans
- Radio-controlled models (drones, cars)
- Medical devices and laboratory equipment
- Office automation equipment (printers, scanners)
