When your application demands a bearing that stays put under radial load while fitting into a recessed bore, standard deep-groove bearings fall short. Engineers, hobbyists, and repair technicians working on small motors, 3D printers, inline skates, and RC drivetrains rely on flanged ball bearings 2RS to lock axially without a separate retaining ring — saving assembly time and reducing part count.
This listing covers the F6000RS through F6006RS series: flanged deep-groove ball bearings with dual contact rubber seals (2RS) and a pressed-steel or stamped flange on the outer ring. Bore diameters range from 10 mm (0.394 in) to 30 mm (1.181 in); outer diameters from 26 mm (1.024 in) to 55 mm (2.165 in); widths from 8 mm (0.315 in) to 13 mm (0.512 in). Available in packs of 1, 10, 30, or 50 pieces.
Typical use cases include flanged ball bearings 2RS for 3D printer extruder idlers and carriage wheels, small electric motor end-shields, skateboard and longboard axles, and light-duty conveyor rollers where the flange provides a positive axial stop without machining a shoulder into the housing.

Match the bearing bore (inner diameter) to your shaft diameter and the outer diameter to your housing bore. Each size in this series is designated by its bore: F6000RS = 10 mm bore, F6001RS = 12 mm, F6002RS = 15 mm, F6003RS = 17 mm, F6004RS = 20 mm, F6005RS = 25 mm, F6006RS = 30 mm. Confirm all three dimensions — bore, OD, and width — against your application drawings before ordering.
The flange is a radial lip on the outer ring that seats against the face of the housing bore, preventing the bearing from being pushed through axially. This eliminates the need for a machined shoulder or snap ring in many designs. If your housing is a through-bore without a shoulder, a flanged bearing is the straightforward solution. If your housing already has a shoulder, a standard (non-flanged) 6000-series bearing may also work.
2RS indicates dual rubber contact seals on both sides of the bearing. The seals press lightly against the inner ring to block contaminants. This makes 2RS bearings well-suited for dusty or lightly moist environments. The trade-off is a small increase in friction torque compared to open or shielded (ZZ) bearings, so 2RS variants are typically used at moderate speeds rather than very high RPM applications.
The steel rings and balls offer standard corrosion resistance suitable for dry indoor environments. The 2RS rubber seals help keep moisture out of the raceway, extending service life in lightly humid conditions. For applications with direct water exposure, wash-down environments, or salt spray, consider stainless steel bearings instead. Contact us to confirm material specifications for your specific environment.
Yes — these are among the most common applications for the F6000–F6006 2RS series. For 3D printer idler pulleys and carriage wheels, the F6000RS (10 mm bore) and F6001RS (12 mm bore) are frequently used. For skateboard axles, F6000RS and F6001RS fit most standard axle diameters. For small DC or stepper motors, match the bore to the motor shaft diameter. Always verify the exact dimensions against your component drawings.
Order 1 pc for prototyping or a single repair. Order 10 pcs if you are building a small batch of assemblies or want spares on hand. Order 30 or 50 pcs for small-scale production runs or if you maintain equipment with multiple bearing points of the same size — bulk packs offer a lower per-unit cost.
Yes. The bearings are factory-filled with grease behind the rubber seals and are ready to install without additional lubrication in standard operating conditions. The sealed design retains the grease for the service life of the bearing under normal loads and speeds. If your application involves elevated temperatures or very high speeds, contact us to confirm suitability.
