W 627/6 R-2Z Bearing Product Overview & Core Advantages
The W 627/6 R-2Z is a metric 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, a shielded design (2Z) for contaminant protection, and pre-lubrication with grease for immediate, maintenance-free operation. This bearing is ideal for applications demanding high rotational accuracy, long service life, and operation within a wide temperature range.
Model Code Breakdown
The model number W 627/6 R-2Z can be decoded as follows:
- W 627/6: Indicates the bearing series and size. The '6' denotes a 6 mm bore diameter.
- R: Signifies the presence of a flange on the outer ring, facilitating secure and simplified mounting.
- 2Z: Denotes that the bearing is equipped with shields on both sides. This provides effective protection against contamination while allowing for higher speed capabilities compared to contact seals.
W 627/6 R-2Z Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured from stainless steel for the rings, balls, and cage, ensuring high corrosion resistance and durability in challenging environments.
- Flanged Design: The outer ring flange (Flange outer diameter: 11.2 mm) enables precise axial location and simplifies bearing housing design, reducing assembly time and cost.
- Contamination Protection: The non-contact shields (2Z) help retain lubricant and exclude larger particulate contaminants, contributing to a longer operational lifespan and consistent performance.
- Ready-to-Use Lubrication: Pre-filled with grease, the bearing is maintenance-free and immediately operational, suitable for its entire specified temperature range of -30° to 120 °C.
- Precision and Speed: Built to P0 tolerance class and CN radial internal clearance, it ensures smooth and quiet operation, with a limiting speed of 60,000 rpm.
W 627/6 R-2Z Bearing Typical Application Areas
The W 627/6 R-2Z is ideally suited for compact, high-speed mechanisms across various industries, including:
- Precision Small Motors: Such as those in drones, RC models, and small cooling fans.
- Medical and Dental Equipment: Including handheld tools and small pumps requiring reliability and corrosion resistance.
- Office Automation Equipment: Applications in printers, scanners, and copiers.
- Instrumentation and Control Systems: Used in precision gauges, encoders, and small robotic joints.
