Flanged Miniature Ball Bearings
Product Overview
Flanged Miniature Ball Bearings combine compact deep groove bearing geometry with an integrated flange on the outer ring. The flange provides a positive locating surface that simplifies axial positioning, helps prevent movement in the housing, and reduces the need for additional shoulders or retaining components in space-limited assemblies.
These bearings support radial loads and limited axial loads in both directions while providing low friction, quiet rotation, and stable performance at high speed. Open, ZZ shielded, and 2RS sealed options are available, together with chrome steel, stainless steel, low-noise grease, and precision-grade configurations.
ETM supplies flanged miniature bearings for OEM production with controlled dimensions, clearance, lubrication, noise level, flange geometry, marking, and packaging. They are suitable for compact motors, instruments, rollers, office equipment, medical devices, robotics, home appliances, and other assemblies requiring accurate bearing location.

FAQs
What is the purpose of the flange on a miniature bearing?
The integrated outer-ring flange provides a locating shoulder that simplifies axial positioning, helps prevent housing movement, and can reduce additional retaining components.
What loads can flanged miniature ball bearings support?
They primarily support radial loads and can carry limited axial loads in both directions. Selection should consider load, speed, fit, clearance, lubrication, and flange support.
Which closure options are available?
ETM can supply open, ZZ metal-shielded, and 2RS rubber-sealed versions, with closure type selected according to torque, contamination, grease retention, and speed.
How should I select the correct flange dimensions?
Confirm bore diameter, outside diameter, width, flange outside diameter, flange width, housing geometry, tolerance, and axial locating requirements before selection.
Where are flanged miniature bearings commonly used?
Common uses include office equipment, medical devices, robotics, home appliances, power tools, instruments, guide rollers, compact motors, and precision assemblies.
Can ETM customize flanged miniature ball bearings?
Yes. ETM supports custom size, flange dimensions, tolerance, clearance, material, seal type, grease, noise grade, marking, packaging, and stable batch supply.
