W 605 R-2Z Bearing Product Overview & Core Advantages
The W 605 R-2Z is a metric single row deep groove ball bearing engineered for precision applications requiring compact design and reliable performance. Featuring stainless steel construction throughout (rings, balls, and cage) and integrated shields (2Z), this bearing offers excellent corrosion resistance and contamination protection. Its optimized geometry enables smooth operation at high speeds (up to 53,000 rpm) while maintaining high radial load capacity. Pre-lubricated with grease, it delivers long service life with minimal maintenance, making it ideal for applications demanding high reliability and consistent performance in demanding environments.

W 605 R-2Z Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The raceway design enables the bearing to handle both radial and moderate axial loads in either direction, providing versatile load capacity in compact dimensions.
All-Stainless Steel Construction: Rings, balls, and cage manufactured from stainless steel ensure excellent corrosion resistance and suitability for harsh environments, washdown applications, and medical equipment.
Flanged Outer Ring: The integrated flange (16 mm diameter, 1 mm thickness) simplifies precise axial positioning during assembly and reduces housing machining requirements.
Double Shield Protection: Non-contact steel shields on both sides effectively retain grease lubrication while excluding contaminants, enabling maintenance-free operation throughout the bearing's service life.
High-Speed Capability: The optimized stainless steel cage and precision manufacturing contribute to smooth operation at high rotational speeds up to 53,000 rpm.
