Ten pieces of F6001ZZ ball bearings, shielded on both sides, with dimensions 12 x 28 x 8 mm. These are standard deep groove ball bearings designed for smooth, lowfriction rotation in compact assemblies. Key benefits Provides reliable, lowfriction rotation for small mechanical assemblies. ZZ shielding protects the bearing interior from dust and contaminants, helping to extend service life with minimal maintenance. Precise 12 mm bore fits 12 mm shafts, enabling straightforward replacement and upgrade in existing designs. Compact size (outer diameter 28 mm, width 8 mm) allows use in tight spaces without compromising performance. Deep groove design supports a range of radial loads and can operate at relatively speeds for its size. Tenpiece pack offers convenient supply for multiple projects or spare parts inventory. Consistent manufacturing quality helps ensure predictable performance across all pieces in the pack. Key attributes Model: F6001ZZ Type: Ball bearing, deep groove Shielding: ZZ (two shields) Bore: 12 mm Outer diameter: 28 mm Width: 8 mm Quantity: 10 pcs Material: Standard bearing construction (not specified) Applications and use cases 3D printer components: suitable for axis bearings, idlers, or gantry support where a 12 mm shaft is used. Hobby robotics and RC projects: suitable for rotating joints, wheels, or actuated mechanisms requiring a compact, shielded bearing. Lightduty equipment and small appliances: appropriate for small conveyors, sliding guides, or other assemblies needing smooth rotation with modest loads. Installation and compatibility notes Fits shafts with 12 mm diameter; ideal for standard 12 mm shaft applications. Shielded (ZZ) design aids in protecting internal parts from dust and debris, reducing maintenance frequency. Compatible with common deep groove bearing mounting practices; ensure proper alignment and secure housings to achieve performance.
