694 Bearing Product Overview & Core Advantages
The 694 metric ball bearing is a single row deep groove ball bearing designed for high-performance radial load applications. Characterized by its compact bearing dimensions (4mm bore, 11mm OD, 4mm width), this bearing offers reliable operation in precision mechanisms. Its open design allows for versatile lubrication options, while the ABEC1 tolerance class ensures consistent running accuracy. Constructed entirely from chrome steel (rings and balls) with a stainless steel cage, it delivers excellent durability and corrosion resistance, making it ideal for applications demanding high reliability and long service life.
694 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 694 | Standard series designation for a metric, single row deep groove ball bearing with a 4mm bore, 11mm OD, and 4mm width. |
| Open | No seals or shields, allowing for high-speed operation and custom lubrication regimes. Requires external contamination protection. |
| ABEC1 | Defines the precision tolerance class, ensuring controlled runout and dimensional accuracy for smooth operation. |
| MC3 | Specifies the radial internal clearance group (0.002mm to 0.013mm), optimized for general operating conditions. |
694 Bearing Structural Features & Performance Benefits
- Optimized Radial Load Capacity: The deep groove raceway and complement of seven precision chrome steel balls are engineered to efficiently support significant radial dynamic loads (183 lbf) and static loads (63 lbf).
- High-Speed Capability: The lightweight stainless steel cage precisely guides the balls, minimizing friction and enabling a limiting speed of 48,000 rpm, making it suitable for high-speed applications.
- Precision Engineering: Manufactured to ABEC1 precision standards with tight diameter and width tolerances, this bearing provides smooth, low-vibration, and low-noise operation essential for sensitive equipment.
- Robust Material Construction: The use of chrome steel for rings and balls provides high hardness and wear resistance, while the stainless steel cage offers enhanced corrosion resistance and cage integrity.
- Standard Internal Clearance (MC3): The specified radial internal clearance is suited for most common operating conditions, ensuring optimal performance without excessive play or preload.
694 Bearing Typical Application Areas
- Small Precision Motors: Ideal for spindle support in miniature DC motors, stepper motors, and fan motors.
- Office Automation Equipment: Commonly used in printers, scanners, and copiers for paper feed rollers and scanner carriages.
- Medical Devices and Instrumentation: Suitable for low-noise, high-reliancy applications in dental handpieces, small pumps, and analytical instruments.
- Radio Control Models and Drones: Used in high-speed motor shafts and gearboxes due to their lightweight and high-speed capabilities.
- Precision Mechanical Systems: Applied in encoders, gauges, and small gearboxes where compact size and accurate rotation are critical.
