R3ZZST-W64F Bearing Product Overview & Core Advantages
The R3ZZST-W64F is a precision miniature ball bearing designed for demanding applications requiring high reliability in compact spaces. As a single row deep groove ball bearing with shielded construction and Solid Oil lubrication, it delivers robust radial load capacity and consistent performance. Its inch dimensions, ABEC 1 precision, and pre-lubricated design make it an ideal solution for applications where maintenance-free operation, compact design, and reliable performance are critical.
R3ZZST-W64F Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Advantage |
|---|---|---|
| R3 | Bearing series code, indicating a specific cross-section and size series. | Standardized dimensions for easy integration and replacement. |
| ZZ | Double-sided shielded (non-contact metal shields). | Effective protection against contamination while maintaining high-speed capability. |
| ST | Indicates the bearing is pre-lubricated with Solid Oil. | Eliminates oil leakage, provides long-term lubrication, and enables maintenance-free operation. |
| W64 | A specific variant or material code within the series. | Denotes specific manufacturing or material specifications for consistent performance. |
R3ZZST-W64F Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & Single Row Design: Optimized for handling significant radial loads and moderate axial loads in both directions, providing versatile load capacity in a compact form factor.
- Double-Shielded (ZZ) Construction: Non-contact metal shields on both sides effectively exclude contaminants like dust and debris, enhancing bearing life and reliability without significantly increasing friction or heat generation, supporting a limiting speed of 50,000 rpm.
- Solid Oil Lubrication (ST): The bearing is filled with a polymer matrix saturated with lubricating oil. This technology prevents oil leakage, even at high speeds or in vertical orientations, and ensures consistent lubrication over a wide temperature range (-30°C to 120°C), making it truly maintenance-free.
- Chrome Steel Construction: All components (rings, balls, cage) are manufactured from high-carbon chrome steel, providing excellent hardness, wear resistance, and durability for long service life.
- ABEC 1 Precision: Manufactured to ABEC 1 (ISO Class P0) tolerance standards, ensuring reliable running accuracy, smooth operation, and reduced vibration for general precision applications.
R3ZZST-W64F Bearing Typical Application Areas
The R3ZZST-W64F is engineered for high-performance in compact and precision-driven systems. Its key application areas include:
- Small Precision Motors: Ideal for spindle and rotor support in miniature DC motors, stepper motors, and servo motors.
- Office Automation Equipment: Critical components in printers, scanners, copiers, and fax machines.
- Medical Devices and Instrumentation: Used in dental handpieces, small pumps, and analytical instruments where reliability and cleanliness are paramount.
- Computer Peripherals: Hard disk drives, cooling fans, and optical disk drives.
- Robotics and Automation: Joint and drive components in small robotic arms and precision gearboxes.
