W 624 R-2Z Bearing Product Overview & Core Advantages
The W 624 R-2Z is a miniature deep groove ball bearing designed for precision applications requiring compact dimensions and reliable performance. This single row bearing excels in handling radial loads and is characterized by its stainless steel construction, which provides excellent corrosion resistance. Its shielded design (2Z) and pre-applied grease lubrication make it a robust, low-maintenance solution for high-speed operations, with a compact 4 mm bore and 13 mm outer diameter ideal for space-constrained assemblies.
