W 627/5-2Z Bearing Product Overview & Core Advantages
The W 627/5-2Z is a miniature deep groove ball bearing engineered for precision applications requiring compact design and reliable performance. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantages include the ability to handle radial loads efficiently and its shielded design (2Z) which retains factory-applied grease and protects against contaminant ingress, making it a robust, low-maintenance solution for demanding environments.
W 627/5-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| W 627/5 | Basic bearing designation for a metric, single-row deep groove ball bearing with a 5mm bore. |
| 2Z | Indicates the bearing is shielded on both sides. This provides effective protection against contaminants while minimizing friction, contributing to the bearing's limiting speed. |
W 627/5-2Z Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With dimensions of 5x8x2.5 mm and a weight of just 0.000407 kg, this bearing is ideal for space-constrained and weight-sensitive applications.
- Corrosion Resistance: All components, including rings, balls, and cage, are made of stainless steel, ensuring long-term performance in humid or corrosive environments.
- Sealed & Pre-Lubricated: The shielded (2Z) construction seals in the factory-applied grease, providing long-term, maintenance-free operation and protecting the bearing's internal radial internal clearance (CN).
- Precision Performance: Manufactured to P0 tolerance class with tight diameter and width tolerances, ensuring consistent and reliable operation in precision assemblies.
W 627/5-2Z Bearing Typical Application Areas
- Precision Instruments: Optical encoders, small gauges, and medical devices.
- Small Electric Motors: Miniature DC motors and stepper motors.
- Office Automation Equipment: Printers, scanners, and copiers.
- Robotics and RC Models: Small joints, gears, and drive systems.
