When your build demands a bearing that seats flush against a housing wall without a separate retaining ring, a flanged deep groove ball bearing is the right call. Engineers, makers, and repair technicians working on 3D printers, RC vehicles, robotics arms, and small appliances rely on the F6xx and F68x/F69x series because the flange locks axial position instantly — no press-fit guesswork, no extra hardware.
This listing covers the full flanged ZZ series from F604ZZ through F699ZZ, including the F62x, F63x, F68x, and F69x sub-families. Each flanged ball bearing is double shielded (ZZ) with steel dust shields on both sides to retain grease and block contamination. Inner diameters run from 3 mm (≈ 0.118 in) to 9 mm (≈ 0.354 in); outer diameters from 7 mm to 26 mm; widths from 3 mm to 8 mm. Rings and balls are chrome steel (GCr15 equivalent); the cage is typically stamped steel. Available in quantities of 1, 5, 10, or 50 pieces per order.
Typical use cases include flanged ball bearings for 3D printer extruder idlers and Z-axis lead screws, flanged bearings for RC car differential and steering knuckles, and miniature flanged bearings for servo motors and robotic joint pivots where axial location must be precise and space is at a premium.
The raised flange on the outer ring seats against the housing face, eliminating the need for snap rings or retaining clips and reducing assembly steps in tight enclosures.
Both sides are sealed with non-contact steel shields that retain factory-applied grease and block dust, metal chips, and debris from reaching the raceways during operation.
Inner and outer rings are machined from chrome steel (GCr15 equivalent) for consistent hardness, fatigue resistance, and dimensional accuracy across the full size range.
Twenty-nine models span bore diameters from 3 mm to 9 mm and outer diameters from 7 mm to 26 mm, covering the most common miniature and sub-miniature flanged bearing applications in one listing.
Order 1, 5, 10, or 50 pieces per model. Single-piece options suit prototyping and repair; 50-piece packs reduce per-unit cost for production runs and stocking purposes.
Dimensions follow standard flanged bearing designations, making these a direct dimensional replacement for worn or failed bearings in existing equipment without housing modification.

Match the three dimensions stamped or printed on your existing bearing: inner diameter (ID) × outer diameter (OD) × width. For example, if your bearing reads 6 × 17 × 6 mm, that is the F606ZZ. Cross-reference the model list in the variant selector above — each option shows the model number followed by its dimensions in parentheses.
All are flanged deep groove ball bearings with the same ZZ double-shield construction, but they differ in the ratio of outer diameter to inner diameter. The F68x series has a notably smaller OD relative to its ID compared to the F60x series, making it useful where radial space is very limited. The F62x and F63x series fall between the two extremes. Choose based on the housing bore and shaft diameter your application requires.
These flanged ball bearings are designed for general-purpose and light-duty precision applications. They are appropriate for moderate speeds found in 3D printers, RC vehicles, and small servo motors. For very high-speed brushless motor applications with specific ABEC tolerance requirements, confirm the speed rating against your motor's RPM specification. Contact us if you need rated speed data for a specific model.
The rings and balls are chrome steel, which is not inherently corrosion-resistant. The ZZ steel shields provide a barrier against splashing and light moisture, but prolonged exposure to water, salt spray, or corrosive chemicals will cause rust. For wet or corrosive environments, consider stainless steel flanged bearings instead. These bearings are best suited for dry or lightly lubricated indoor conditions.
No re-lubrication is required under normal operating conditions. The ZZ steel shields retain the factory-applied grease for the service life of the bearing in typical light-to-medium duty use. If the bearing is operated at elevated temperatures or under heavy loads beyond its rated capacity, the grease may degrade faster and the bearing should be replaced rather than re-greased, as the shields are not designed to be removed and refitted.
The flange is a raised lip on the outer ring that protrudes radially beyond the standard OD. When the bearing is pressed into a housing, the flange seats against the housing face and prevents the bearing from being pushed through axially. This eliminates the need for snap rings, circlips, or shoulder machining to locate the bearing, which simplifies housing design and speeds up assembly — particularly valuable in 3D-printed or thin-walled housings.
Order 1 piece for a single repair or prototype build where you need to verify fit before committing. Order 5 or 10 pieces if you are building a small batch of assemblies or want spares on hand. Order 50 pieces for production runs or stocking purposes — the per-unit price decreases significantly at higher quantities, as reflected in the pricing shown for each variant.
