698 Bearing Structural Features & Performance Benefits
Optimized Radial Load Capacity: The deep groove raceway and construction with 7 high-grade chrome steel balls are engineered to efficiently support significant radial loads, with a dynamic rating of 428 lbf.
Precision and Smooth Operation: Built to ABEC1 precision class tolerances, this bearing ensures consistent performance and low vibration. The stainless steel cage maintains ball spacing for smooth, high-speed operation up to 36,000 rpm.
Versatile Material Compatibility: Constructed entirely from chrome steel (rings and balls) with a stainless steel cage, the bearing offers excellent resistance to wear and is suitable for a temperature range of -30°C to 110°C.
Standard Internal Clearance: Features an MC3 radial internal clearance (0.002mm to 0.013mm), making it suitable for a wide array of common industrial applications.
