W 619/9 R-2RS1 Bearing Structural Features & Performance Benefits
The design of the W 619/9 R-2RS1 translates into distinct performance benefits. The deep groove raceway and single row of balls are optimized to handle significant radial loads. The inclusion of a flanged outer ring enhances mounting stability and simplifies assembly in housings. The 2RS1 double seals are a critical feature, creating an effective barrier against dust and moisture, which extends bearing life and ensures consistent performance. Manufactured entirely from stainless steel, the bearing, including rings, balls, and cage, offers excellent corrosion resistance, making it suitable for harsh environments. Being pre-lubricated with grease, it is ready for immediate use and requires no maintenance, supporting a limiting speed of 22,000 rpm.
