When your shaft needs a bearing that stays put axially without a separate retaining ring, standard deep groove bearings fall short. Engineers, machine builders, and DIY equipment builders working with compact assemblies rely on flange deep groove ball bearings to simplify housing design and reduce part count — all without sacrificing radial load capacity.
This listing covers the F6000 to F6006 series in two seal configurations: RS (rubber contact seal) for dusty or lightly wet environments, and ZZ (metal shield) for high-speed, lower-friction applications. Inner 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), and widths from 8 mm to 13 mm — covering the most common compact shaft sizes in the F6000 series.
Typical use cases include 3D printer extruder and idler assemblies requiring flanged retention, small conveyor roller end supports where axial location matters, RC vehicle and hobby robotics drivetrains needing a low-profile sealed bearing, and light industrial jigs or fixtures where a flanged shoulder replaces a machined housing step.
The machined flange on the outer ring provides a positive axial stop against the housing face, eliminating the need for snap rings or retaining clips in many designs.
RS rubber contact seals block fine particles and light moisture while retaining grease. ZZ metal shields offer lower drag torque and suit higher-speed, dry-environment applications.
Seven model sizes from 10 × 26 × 8 mm up to 30 × 55 × 13 mm cover the most common compact shaft diameters in the F6000 series, available in single-piece or multi-pack quantities.
Each bearing ships pre-lubricated with grease suited for general-purpose radial load service — no additional lubrication required before installation in most applications.
The single-row deep groove raceway geometry handles radial loads efficiently and accommodates minor axial loads in both directions, making these bearings versatile across a wide range of light-duty machinery.
Available in 1, 2, 5, or 10-piece packs so you can order exactly what your project or maintenance stock requires — from a single replacement to a workshop supply.

Choose RS (rubber contact seal) when your application involves dust, fine particles, or occasional light moisture — the contact lip actively blocks contamination and retains grease longer. Choose ZZ (metal shield) when operating speed is a priority and the environment is relatively clean and dry; the non-contact shield produces less friction and allows higher RPM. Both seal types share identical envelope dimensions within each model number, so you can swap between them without modifying your housing.
The flange is a raised lip machined onto the outer ring. It seats against the face of the housing bore, providing a positive axial stop that prevents the bearing from being pushed through the housing under axial load. This eliminates the need for a separate snap ring, circlip, or machined shoulder in many designs — simplifying assembly and reducing part count.
Match the bearing's inner diameter (ID) to your shaft diameter. The model numbers correspond to the following IDs: F6000 = 10 mm, F6001 = 12 mm, F6002 = 15 mm, F6003 = 17 mm, F6004 = 20 mm, F6005 = 25 mm, F6006 = 30 mm. Also verify that your housing bore matches the outer diameter (OD) listed for your chosen model. The full ID × OD × Thickness dimensions are shown in each variant option.
The RS rubber seal provides a degree of protection against light moisture and splash, making it more suitable than ZZ for mildly humid conditions. However, neither RS nor ZZ variants in this series are rated for continuous immersion or highly corrosive chemical exposure. For such environments, consider stainless steel bearings or bearings with additional sealing. Contact us to confirm suitability for your specific conditions.
Yes, to a limited extent. Single-row deep groove ball bearings can accommodate moderate axial loads in both directions alongside their primary radial load capacity. The flange itself is not a load-bearing surface for axial thrust — it is a locating feature. For applications with significant axial loads, consult the bearing's dynamic and static load ratings and consider angular contact or thrust bearing designs if axial loads dominate.
No. These bearings are pre-greased at the factory and sealed, so they are ready to install straight from the packaging in most general-purpose applications. Do not wash or re-grease sealed bearings before installation, as this can displace the factory grease and introduce contamination. If your application involves extreme temperatures or speeds outside the standard range, contact us to confirm lubricant compatibility.
Order 1 pc if you need a single replacement or are prototyping. Order 2 pcs for applications requiring a bearing at each end of a shaft (common in roller and spindle assemblies). Order 5 or 10 pcs if you are building multiple units, stocking spares for maintenance, or want a lower per-unit cost. All pack sizes ship the same bearing — only the quantity differs.
