NTN-SNR 51111A Thrust Ball Bearing

NTN-SNR 51111A thrust ball bearing is a single‑direction axial‑load bearing in the 511 family, engineered to carry axial loads in one direction with a compact form factor. The model specifies a thrust bearing height of 16 mm and a static axial load rating (C0a) of 93.2 kN, making it suitable for applications where reliable axial support is required within tight space constraints. Like other thrust ball bearings, it comprises separable components, a construction detail that facilitates straightforward mounting and replacement, and it aligns with NTN‑SNR’s catalog guidance on standard cage types and range within the thrust bearing family. This bearing is typically employed in machinery where axial loading must be transmitted while allowing shaft rotation, including gearboxes, pumps, and conveyors, among other assemblies that demand precise, one‑direction axial support. Within the 51111 designation, users can expect the model to be part of a broader lineup that offers variations in cage material and clearance depending on the specific variant, so consult the exact NTN‑SNR spec sheet for your selected lot to confirm cage type and tolerance.
