W 630/1.5 R-2Z Bearing Product Overview & Core Advantages
The W 630/1.5 R-2Z is a miniature single row deep groove ball bearing engineered for applications demanding compact design and reliable performance. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to handle primarily radial loads efficiently while offering a degree of axial load support. The inclusion of shielded seals ensures contaminant protection and grease retention, making it a robust and durable choice for precision instruments and small mechanisms.
Model Code Breakdown
| Code Segment | Interpretation | Technical Significance |
|---|---|---|
| W 630/1.5 | Bearing Series & Size | Denotes a specific miniature bearing series with a 1.5 mm bore diameter. |
| R | Flanged Outer Ring | Indicates the bearing features an outer ring flange, facilitating simplified axial location and mounting. |
| 2Z | Shielded on Both Sides | Specifies non-contact steel shields on both sides, offering effective protection against contaminants while allowing for high-speed operation. |
W 630/1.5 R-2Z Bearing Structural Features & Performance Benefits
- Compact and Lightweight Design: With a 1.5 mm bore, 6 mm outside diameter, and a weight of only 0.000508 kg, this bearing is ideal for space-constrained and weight-sensitive applications.
- Corrosion Resistance: Manufactured from stainless steel for the rings, balls, and cage, the bearing is suitable for use in humid or corrosive environments.
- Simplified Mounting: The flanged outer ring (R-designation) allows for easy axial positioning, reducing assembly complexity and cost.
- Contaminant Protection and Pre-lubrication: The 2Z shields protect the internal components from dust and other particles, while the pre-applied grease ensures immediate operation and long-term, maintenance-free performance within its specified temperature range.
- Precision Performance: Manufactured to P0 tolerance class with a standard (CN) radial internal clearance, it provides consistent and reliable operation for precision mechanisms.
W 630/1.5 R-2Z Bearing Typical Application Areas
This miniature flanged bearing is commonly used in:
- Precision Instruments: Optical encoders, small measuring devices.
- Small Motors and Gearboxes: Micro-DC motors, miniature gearheads.
- Office Automation Equipment: Printers, scanners, copiers.
- Medical Devices: Small surgical tools, diagnostic equipment.
- Robotics: Joints and actuators in small-scale robotic arms.
