S694zz Bearing Product Overview & Core Advantages
The 694ZZ is a miniature deep groove ball bearing designed for compact, high-precision applications. This single row, shielded bearing is constructed entirely from stainless steel, offering excellent corrosion resistance. Its primary advantages include reliable radial load capacity, smooth operation at moderate speeds, and long service life in demanding environments. The integral shields protect against contamination, making it a robust and maintenance-friendly solution for applications where space is limited and reliability is critical.
S694zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 694 | Bearing series designation, indicating a miniature bearing with specific dimensional proportions. | Defines the core size and type as a deep groove ball bearing. |
| ZZ | Denotes shielded on both sides. | The shields provide effective protection against dust and other particulates, retaining lubricant and extending bearing life. The bearing is not sealed and requires lubrication. |
S694zz Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With dimensions of 4x11x4 mm and a weight of only 1.75 g, this bearing is ideal for applications with severe space and weight constraints.
- Stainless Steel Construction: All components, including rings, balls, cage, and shields, are made from stainless steel, providing superior corrosion resistance and suitability for harsh or washdown environments.
- Radial Load Capacity: The deep groove raceway and 7-ball design are optimized to handle radial dynamic loads up to 165 lbf effectively.
- Shielded Protection: The non-contact ZZ shields protect the internal components from contamination without significantly increasing friction, contributing to a limiting speed of 43,200 rpm.
- Precision & Clearance: Manufactured to ABEC1 tolerance class with an MC3 radial internal clearance (0.002mm to 0.013mm), ensuring consistent and smooth operation.
S694zz Bearing Typical Application Areas
This bearing is widely used in compact, high-speed devices across various industries, including:
- Small Electric Motors: Ideal for spindle motors in hard disk drives, cooling fans, and small power tools.
- Precision Instruments: Used in optical encoders, medical devices, and laboratory equipment.
- Office Automation: Found in printers, scanners, and copiers.
- Radio Control Models: Commonly used in high-performance servos and drone motors.
- Food and Beverage Equipment: Suitable for applications requiring corrosion resistance and frequent washdowns.
