S602x 2rs Bearing Product Overview & Core Advantages
The 2.5mm bore miniature ball bearing is a single row deep groove ball bearing engineered for precision applications requiring compact design and reliable performance. Constructed entirely from stainless steel with a sealed nitrile rubber shield, it offers excellent corrosion resistance. This bearing is designed to primarily handle radial loads and is characterized by its ABEC1 precision class, making it suitable for high-speed operations up to 54,000 rpm. Its small size and low weight of 0.61g make it ideal for space-constrained, high-precision assemblies.

S602x 2rs Bearing Structural Features & Performance Benefits
The bearing's performance is derived from its robust construction. The single row deep groove raceway is optimally designed to support significant radial dynamic loads (95 lbf). The use of a stainless steel cage and components ensures dimensional stability and resistance to corrosion. The integrated nitrile rubber seal effectively retains lubrication and excludes dust and moisture, which is critical for maintaining performance in challenging environments. The specified MC3 radial internal clearance provides an optimal balance, minimizing noise and vibration while accommodating thermal expansion during high-speed operation. This combination of features results in a long service life and consistent performance.
