从China供应商批发进口681 Chrome Steel Miniature Ball Bearing — FOB条款

The 681 miniature ball bearing is a deep groove precision component with dimensions of 1x3x1mm, constructed from chrome steel (GCr15 / AISI 52100). This material provides high hardness and wear resistance, making it suitable for applications requiring smooth rotation under high speeds or loads. The bearing’s compact size and precision engineering allow it to fit into tightly constrained assemblies.

Chrome steel bearings are standard for miniature applications due to their durability and resistance to deformation under stress. The 681 model is commonly used in medical instruments, small motors, hard drives, and aerospace instrumentation, where reliability and longevity are critical. Typical dynamic load ratings for bearings of this size range from 0.5 to 1.5 kN, while static load ratings are lower due to the small contact area.

This bearing is sourced in lots with a minimum order quantity of 1000 pieces, packaged in polybags to prevent contamination and damage during transit. Buyers in electronics, robotics, and precision engineering sectors rely on such components for consistent performance in high-precision environments. Confirm the bearing’s tolerance class (e.g., ABEC-1, ABEC-3) to match your application’s requirements.
