F608ZZ Shielded Flanged Ball Bearing | 8 × 22 × 7 mm, 25 mm Flange

F608ZZ flanged ball bearing with metal shields on both sides. It retains the main 8 × 22 × 7 mm dimensions of a 608ZZ and adds a nominal 25 mm diameter flange.

Nominal dimensions

• Reference: F608ZZ.
• Inner diameter: 8 mm.
• Body outer diameter: 22 mm.
• Overall width: 7 mm.
• Flange diameter: 25 mm.
• Flange width: 1.5 mm.
• Metal shields on both sides.
• Supplied quantity: 1 bearing.

Applications

It can be used in rollers, tensioners, supports, extruders and rotating mechanisms requiring a 608 bearing with a flanged axial reference. Bearings from this family are found in many RepRap and Prusa designs and 3D printer modifications, but the flanged version requires a suitable housing.

608ZZ compatibility

The main body shares the 8 × 22 × 7 mm dimensions of a conventional 608ZZ. However, the 25 mm flange prevents it from being considered a direct replacement when the mount does not provide sufficient clearance or a flange recess.

It must not be confused with a thrust bearing. The flange is primarily used for geometric location and retention, while the bearing remains a radial ball-bearing design.

Non-flanged alternative

Where no flange is required, the 608ZZ bearing measuring 8 × 22 × 7 mm may be used, provided the remaining assembly requirements are compatible.
