Flanged Ball Bearings

Flanged ball bearings are a specially designed type of bearing characterized by a flange (or rim) on either the outer or inner ring. This design not only enhances the structural strength of the bearing but also provides convenient installation and positioning capabilities. Flanged ball bearings are widely used in various mechanical equipment, especially in situations requiring heavy loads and high-speed rotation. AUBEARING manufactures flanged deep groove ball bearings with standard bearing dimensions (common diameter sizes range from 1/8 inch to 1 inch) and offers options for metal shielding and rubber seals to prevent debris and dirt from entering the bearing, while retaining grease to ensure good lubrication and longer service life. Various customization options are available, including materials for rings and balls (chrome steel, stainless steel, ceramics, silicon nitride), brass or polymer cages, lubricants, precision grades (ABEC1-ABEC7), and more. Notably, 304 stainless steel flanged bearings meet FDA standards for use in food processing facilities. Fortunately, AUBEARING also offers miniature flanged bearings and the scarce market option of miniature flanged bearings with extended inner rings. The minimum order quantity (MOQ) is 1.

1. High Load Capacity: Due to the presence of the flange, the bearing can withstand significant axial, radial loads, and torque. This makes it widely applicable in high-load and high-speed mechanical equipment.

2. Compact Structure: The overall structure of the flanged bearing is simple, making installation and maintenance relatively easy. Moreover, due to the flange, it can be directly connected to other components, reducing extra installation steps and parts, thereby lowering installation costs.

3. Low Friction Coefficient: Flanged bearings that utilize rolling friction have a lower friction coefficient compared to sliding friction. This not only reduces power consumption but also minimizes wear and heat generation, thereby extending the bearing's service life.

4. High Speed: Due to the characteristics of rolling friction, flanged bearings can handle high speeds. This makes them widely used in mechanical equipment that requires high-speed rotation.

5. Wide Applicability: Flanged bearings are suitable for various industrial equipment, office machinery, micro motors, dental drills, hard drive motors, stepper motors, fans, pulleys, rollers, robots, medical devices, office equipment, testing instruments, reducers, variable speed devices, power tools, and toys, among others.
