SW R 2 A - 2 Z Precision Deep Groove Ball Bearing | 12x32x10 mm | Double Shielded (2Z)
The SW R 2 A - 2 Z is a premium single-row deep groove ball bearing designed for high-speed industrial applications where robust contamination protection is essential. Featuring a 12 mm bore, 32 mm outer diameter, and 10 mm width, this precision component is manufactured to meet rigorous P0 dimensional standards, ensuring low-vibration operation and excellent rotational accuracy. The defining '2Z' designation signifies two non-contacting metal shields, providing effective protection against dust, debris, and splash contaminants while retaining the high-performance, factory-applied grease for maintenance-free service life. This bearing is the ideal choice for electric motors, precision pumps, HVAC systems, and power transmission equipment requiring reliable performance in moderately challenging environments.
Built under the strict quality control protocols of the SW brand, the R 2 A - 2 Z utilizes hardened steel rings and high-grade ball elements to deliver exceptional dynamic (Cr) and static (C0r) load ratings relative to its size. Its optimized internal geometry minimizes friction torque, allowing for sustained high-speed operation up to 20,000 RPM while reducing operating temperatures. By specifying the SW R 2 A - 2 Z, procurement teams ensure equipment uptime and reduced total cost of ownership through superior component longevity and predictable reliability, making it a critical asset for standardizing maintenance stock across various industrial platforms.
Key Features
