R4ZZST-W64F Bearing Product Overview & Core Advantages
The R4ZZST-W64F is a precision miniature ball bearing designed for demanding applications requiring high reliability and consistent performance. As a single row radial ball bearing, it efficiently handles radial loads while offering a compact design. Its key advantages include the use of Solid Oil lubrication for long-term, maintenance-free operation and shielded construction for effective contamination protection. Manufactured to ABEC 1 / ISO P0 tolerance standards, this inch-series bearing is ideal for applications where space is limited and dependable performance is critical.
R4ZZST-W64F Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| R4 | Indicates a specific series of miniature, inch-size bearings. |
| ZZ | Signifies that the bearing is equipped with shields on both sides (2Z). This provides effective protection against dust and other particulate contaminants. |
| S | Denotes a special internal design or specification. |
| T | Indicates the bearing is lubricated with Solid Oil, a polymer matrix saturated with lubricating oil. |
| W64F | A manufacturer-specific suffix, often indicating a particular variant, material, or performance characteristic. |
R4ZZST-W64F Bearing Structural Features & Performance Benefits
- Shielded Design for Enhanced Protection: The ZZ (double-shielded) construction effectively seals the bearing interior from dust and debris without significantly increasing rotational torque, making it suitable for a variety of environments.
- Maintenance-Free Operation with Solid Oil: The integrated Solid Oil lubrication system ensures a consistent and reliable lubricant supply throughout the bearing's service life. It eliminates the risk of oil leakage and is ideal for applications where re-lubrication is difficult or undesirable.
- Precision Engineering for Smooth Operation: Built to ABEC 1 precision standards with a standard CN radial internal clearance, this bearing offers smooth and quiet running, contributing to the overall efficiency of the assembly.
- Robust Load Capacity: With a dynamic load rating of 283 lbf and a static load rating of 112 lbf, this compact bearing delivers reliable performance under significant radial loads.
- All-Steel Construction: The rings, balls, and cage are manufactured from Chrome Steel, providing excellent durability, wear resistance, and a long operational lifespan.
