626 2rs Bearing Product Overview & Core Advantages
The 626 2RS is a single row deep groove ball bearing designed for reliable performance in demanding applications. Featuring integrated rubber seals (2RS) on both sides, this metric bearing provides excellent protection against contamination while retaining lubrication. Its optimized internal geometry enables it to handle significant radial loads and moderate axial loads in both directions. With ABEC1 precision class and chrome steel construction, it delivers consistent operation and long service life in compact spaces where high reliability is essential.

626 2rs Bearing Structural Features & Performance Benefits
Deep Groove Raceway Design: The optimized raceway geometry enables the bearing to accommodate both radial loads and bidirectional axial loads, making it versatile for various mounting configurations.
Double Rubber Seals (2RS): Nitrile rubber seals provide effective protection against dust, moisture, and other contaminants while maintaining low friction characteristics, extending bearing service life in harsh environments.
Precision Engineering: Manufactured to ABEC1 tolerance class with MC3 radial clearance (0.002-0.013mm), ensuring smooth operation and reduced vibration levels.
High-Quality Materials: Chrome steel rings and balls combined with stainless steel cage provide excellent wear resistance and corrosion protection, supporting the limiting speed of 32,000 rpm.
