W 61901 R-2RS1 Bearing Product Overview & Core Advantages
The W 61901 R-2RS1 is a single row deep groove ball bearing designed for high-precision applications requiring reliable performance in compact spaces. Engineered with stainless steel components, it offers excellent corrosion resistance and durability. Its primary advantage lies in its ability to handle radial loads efficiently while featuring integrated seals (2RS1) that protect against contamination and retain lubrication. This makes it an ideal solution for applications demanding low maintenance, consistent operation, and long service life within its specified temperature range.

W 61901 R-2RS1 Bearing Structural Features & Performance Benefits
Compact & Robust Design: The single row construction with a flanged outer ring provides easy mounting and axial location, enhancing stability in assemblies. The stainless steel cage and components ensure consistent performance and resistance to corrosion.
Superior Sealing & Lubrication: The 2RS1 contact seals effectively shield the bearing from dust, moisture, and other contaminants while retaining the pre-applied grease lubrication. This combination supports a maintenance-free operation and extends bearing life.
High-Speed Capability & Load Handling: With a limiting speed of 19,000 rpm and a radial dynamic load rating of 564 lbf, this bearing is suited for applications requiring rapid rotation and reliable radial load support. The CN radial internal clearance ensures optimal performance under standard operating conditions.
