W 61705 R Bearing Product Overview & Core Advantages
The W 61705 R is a metric single row deep groove ball bearing engineered for high-precision radial load applications. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. Its compact design, with a minimal cross-section, makes it ideal for space-constrained assemblies requiring reliable performance and high limiting speeds up to 26,000 rpm.
