Product Overview and Core Advantages
The 623-2RS1 is a metric single row deep groove ball bearing designed for high-performance applications requiring reliable operation in compact spaces. This sealed bearing excels in handling radial loads and offers exceptional operational stability. Its precision construction with P6 tolerance class ensures consistent performance, making it ideal for applications demanding high rotational accuracy and long service life. The integrated seals and pre-applied grease provide a maintenance-free solution from the outset.
623-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 623 | Standard series designation for a single row deep groove ball bearing with a 3mm bore. |
| 2RS1 | Indicates the bearing is fitted with two contact seals (RS1 type), one on each side, providing effective protection against contaminants and retaining lubricant. |
Structural Features and Performance Benefits
Robust Sealed Design: The 2RS1 contact seals are a critical feature, offering superior protection against dust, moisture, and other contaminants. This significantly enhances bearing life in challenging environments and ensures the integrity of the pre-applied grease lubrication.
High-Precision Performance: Manufactured to a P6 tolerance class, this bearing provides tighter dimensional and running accuracy, resulting in reduced vibration and noise levels, which is essential for precision instruments.
Optimized Material Selection: The combination of chrome steel rings and balls with a stainless steel cage provides excellent durability, corrosion resistance, and reliable operation across the specified temperature range of -30°C to 120°C.
Compact and Lightweight: With compact bearing dimensions (3mm bore, 10mm OD, 4mm width) and a minimal weight of 0.0015 kg, it is perfectly suited for applications where space and weight are critical constraints.
623-2RS1 Bearing Typical Application Areas
- Small Precision Motors: Ideal for spindle support in miniature DC motors and stepper motors.
- Office Automation Equipment: Commonly used in printers, scanners, and copiers.
- Medical Devices: Suitable for small pumps, dental handpieces, and diagnostic equipment.
- Instrumentation and Control Systems: Used in encoders, sensors, and small gearboxes requiring reliable, low-torque rotation.
- Consumer Electronics: Applications in computer cooling fans, small drones, and various handheld devices.
