W 627 R-2Z Bearing Product Overview & Core Advantages
The W 627 R-2Z is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Engineered with stainless steel construction throughout (rings, balls, and cage), it offers superior corrosion resistance. Its key advantages include the ability to handle significant radial loads and moderate axial loads in both directions. The integral shielded design (2Z) effectively protects against contamination while the pre-lubricated state ensures quiet operation and long-term, maintenance-free service. This compact and lightweight bearing is ideal for applications requiring high reliability, precision, and durability.

W 627 R-2Z Bearing Structural Features & Performance Benefits
- All-Stainless Steel Construction: The use of stainless steel for all critical components provides excellent corrosion resistance, making it suitable for harsh environments and washdown applications.
- Flanged Outer Ring: The integrated flange (25mm outer diameter) simplifies bearing mounting and positioning within a housing, reducing assembly time and cost.
- Shielded Design (2Z): The non-contact steel shields on both sides effectively retain grease and protect the internal rolling elements from dust and debris, enhancing bearing service life and reliability.
- Pre-Lubricated & Maintenance-Free: Filled with high-quality grease, the bearing is ready for immediate use and does not require relubrication, offering a maintenance-free solution.
- Precision & High-Speed Capability: Manufactured to P0 tolerance class and featuring a low-friction design, it supports a limiting speed of 38,000 rpm, making it suitable for high-speed applications.
