D/W R1 R-2Z Bearing Product Overview & Core Advantages
The D/W R1 R-2Z is a miniature single row deep groove ball bearing designed for precision applications requiring compact dimensions and reliable performance. This inch-series bearing features stainless steel construction throughout (rings, balls, cage) providing excellent corrosion resistance. Its shielded design (2Z) and factory-applied grease lubrication create a sealed, maintenance-free unit capable of handling radial loads with high rotational accuracy. The combination of compact size, corrosion-resistant materials, and pre-lubricated shielding makes it ideal for applications demanding long service life in challenging environments.
