F698 Bearing Product Overview & Core Advantages
The F698 is a metric single row deep groove ball bearing engineered for reliable performance in compact spaces. Designed primarily for radial loads, this open-type bearing offers high precision operation conforming to ABEC1 tolerance class. Its compact dimensions (8mm bore, 19mm OD, 6mm width) combined with a robust chrome steel construction make it ideal for applications requiring precise rotational accuracy and dependable service life. The bearing requires lubrication and operates effectively within a temperature range of -30°C to 110°C.
