F3-8M Thrust ball Bearings, 10pcs Single Direction Chrome Steel (3x8x3.5mm) Miniature plane axial bearing, for rotating mechanisms, machinery, robotics, low friction

{Specifications} Dimensions (bore diameter x outer diameter x thickness): F3‑8M (3mm x 8mm x 3.5mm), F5‑11M (8mm x 44mm x 4.5mm). Both sizes are specifically designed to efficiently handle pure axial (thrust) loads, making them suitable for applications where radial bearings alone do not provide sufficient axial clearance control. {Operating Parameters} Accuracy class: P0 (ABEC‑1); Dynamic load rating (Cr): 600N; Static load rating (Cor): 480N; Speed limit (grease): 11000 rpm; Speed limit (oil): 15000 rpm; Noise level: Z1. {Unidirectional Axial} The bearings are specifically designed to handle high axial loads in a single direction, with flat raceways that distribute pressure evenly across the balls. Maximises load capacity – making them the preferred choice for vertical shafts, lead screw mechanisms, and clutch assemblies. {Ultra‑Smooth Rotation} Factory‑filled with a high‑viscosity grease formulated for thrust applications, and the hardened steel raceways are precision‑ground to a mirror finish, ensuring that balls roll with minimal friction and nearly zero axial play, while maintaining consistent lubrication. {Assembly Marking} The bearings feature clear markings on the race rings indicating the correct installation direction – ensuring that loads are applied to the designated thrust face during assembly. This reduces the risk of premature failure due to reverse installation, saving time and protecting your equipment.
