Micro flanged ball bearings generally refer to small bearings with inner diameters ranging from 1 to 9 mm. These bearings have a compact structure, low starting torque, and are commonly used in high-speed and low-noise environments. Many very small flanged bearings are made from chrome steel or stainless steel. Flanged bearings with steel retainers and suitable lubricants can operate at a constant temperature of 120°C or intermittently up to 150°C. Beyond these temperatures, the load capacity of chrome steel decreases.
Chrome steel flanged bearings are susceptible to corrosion and are coated with a rust preventive oil to prevent moisture. AUBEARING does not recommend using flanged bearings without any lubricant, as they are prone to corrosion. This can even occur during storage or transportation due to condensation inside protective packaging. The standard retainers or cages for chrome steel flanged miniature bearings are made from SPCC steel strips. Due to space limitations, integral crown-type retainers are more suitable for the smallest and thinnest bearings.
AUBEARING chrome steel flanged miniature bearings are available in open or metal shielded versions. Larger bearings may have rubber or PTFE contact seals or low-friction non-contact rubber seals. Open flanged bearings use oil lubrication, while shielded or sealed flanged bearings typically use grease lubrication.
Micro flanged ball bearings are suitable for industries including model aircraft drones, miniature motors, universal joint motors, dental drills, crushers, stepper motors, massage chairs, push rod motors, computers, blenders, sports equipment, fitness equipment, robotics, machinery, household appliances, medical devices, precision instruments, and others.
AUBEARING provides technical drawings of micro flanged ball bearings with load and speed data for theoretical life calculations. It is recommended to operate bearings well below their maximum rated load and speed to ensure a reasonable ball bearing life.
