W 61800-2Z Bearing Product Overview & Core Advantages
The W 61800-2Z is a single row deep groove ball bearing designed for precision applications requiring high reliability and compact design. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to efficiently support radial loads, while the shielded (2Z) design on both sides retains pre-applied grease and protects against contamination, ensuring long-term performance with minimal maintenance. This makes it an ideal precision bearing for applications demanding high rotational accuracy and durability.
W 61800-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Code | Technical Meaning |
|---|---|---|
| Basic Designation | W 61800 | Stainless steel, single row deep groove ball bearing series with a 10mm bore. |
| Seal Type | -2Z | Bearing with shields on both sides. Protects against contamination and retains lubricant. |
W 61800-2Z Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a bearing size of just 10x19x5 mm and a weight of 0.0051 kg, it is ideal for space-constrained and weight-sensitive applications.
- Corrosion Resistance: All components, including rings, balls, and cage, are made of stainless steel, making it suitable for harsh environments and ensuring a long service life.
- Shielded Protection: The non-contact shields (2Z) effectively protect the bearing interior from dust and other particles while retaining the factory-applied grease lubrication, contributing to its maintenance-free characteristic.
- Precision Performance: Manufactured to P0 tolerance class and standard CN radial internal clearance, it provides reliable and smooth operation for general precision applications.
- Operational Range: Capable of operating within a temperature range of -30°C to 120°C, accommodating a wide variety of operating conditions.
W 61800-2Z Bearing Typical Application Areas
This bearing is commonly used in:
- Precision instruments and measuring devices
- Small electric motors and gearboxes
- Medical and dental equipment
