SW R 2 ZZ Miniature Deep Groove Ball Bearing – 1/8 Inch Bore, Double Shielded
The SW R 2 ZZ is a high-precision miniature deep groove ball bearing designed for applications demanding exceptional speed and minimal friction in constrained spaces. Adhering to the stringent Imperial 'R' series standard, this bearing features hardened 52100 Chrome Steel construction, providing excellent wear resistance and durability under moderate radial and minor thrust loads. The 'ZZ' designation confirms the presence of dual, non-contacting metal shields expertly pressed into the outer ring. These shields prevent macro-contaminants from entering the raceway while effectively retaining the factory-applied synthetic grease, making the R 2 ZZ an essential component for maintenance-sensitive instrumentation.
Optimized for high rotational speeds, this specific R 2 ZZ bearing is commonly utilized in demanding industrial contexts such as precision servo motors, small power transmission shafts, dental equipment, and sensitive measuring instruments. The double-shielded design ensures a high degree of protection without significantly impacting the bearing's low operational torque, thus maximizing energy efficiency. Choosing the SW R 2 ZZ ensures dimensional accuracy compliant with ABEC-1 standards, guaranteeing consistent performance and reliability critical for OEMs and MRO operations requiring reliable, compact motion control solutions.
