Ten pieces of flange ball bearings, model F6803 and F6803ZZ, sized 17 x 26 x 5 mm. The flange mounting design allows easy, precise installation in compact assemblies, while the F6803ZZ version is shielded on both sides to resist dust and debris and extend service life. Key benefits Smooth, lowfriction rotation for reliable performance in small mechanical assemblies. Flange mounting for straightforward alignment and secure attachment to chassis or plates. ZZ shielded design provides dust and moisture resistance to protect the bearing and lubricant. Standard 6803 series dimensions enable broad compatibility with many components and replacements. Set of 10 pieces offers costeffective stocking for multiple projects or spare parts. Key attributes Model: F6803 / F6803ZZ Type: Flange ball bearing (flange mounting design) Size: 17 x 26 x 5 mm (bore 17 mm; outer diameter 26 mm; width 5 mm) Shielding: ZZ (double shield) Quantity: 10 bearings Purpose: Designed for mounting on a shaft with a 17 mm bore and securing to a supporting surface via the flange Compatibility and performance Compatible with standard 17 mm bore shafts and other components sized for 6803 series bearings. Flange design assists with accurate positioning and stable mounting in confined spaces. Shielded on both sides helps reduce contamination risk and maintains lubricant efficiency, supporting longer service intervals in dusty or other challenging environments. Use cases Robotics and hobby projects: mount on small actuators or joints where a flange bearing helps align rotating shafts and reduce play. 3D printers and compact CNC assemblies: use in axis supports or control linkages where space is limited and reliable rotation is critical. Home appliances or small tools requiring replacement bearings in compact housings with a mounting flange for secure installation. What you get 10 pcs F6803 F6803ZZ flange ball bearings, 17 x 26 x 5 mm, shielded on both sides for enhanced protection and longevity.
