626 Bearing Product Overview & Core Advantages
The 626 metric ball bearing is a fundamental single row deep groove ball bearing designed for exceptional reliability in a wide range of applications. Engineered to primarily support radial loads, this open-type bearing offers a compact design with a 6mm bore, making it ideal for space-constrained assemblies. Manufactured to ABEC1 precision tolerances, it ensures consistent performance and smooth operation. Its construction from high-grade chrome steel and a stainless steel cage provides excellent durability and corrosion resistance, establishing it as a versatile and cost-effective solution for general industrial use.

626 Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The deep groove raceway and six precision balls enable efficient handling of radial dynamic loads up to 447 lbf and static loads up to 161 lbf, providing robust support in demanding conditions.
- High-Speed Capability: The lightweight, durable stainless steel cage effectively guides the balls, contributing to a high limiting speed of 32,000 rpm, making it suitable for high-rotation applications.
- Precision & Smooth Operation: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group: 0.002mm to 0.013mm), this bearing ensures low vibration, low noise, and smooth running, which is critical for precision equipment.
- Material Durability: Rings and balls made from chrome steel (GCr15) offer high hardness and wear resistance, while the stainless steel cage provides enhanced corrosion resistance and operational stability.
