51117 Bearing Product Overview & Core Advantages
The 51117 metric thrust ball bearing is engineered for high-precision axial load applications requiring exceptional rigidity and dimensional stability. This thrust bearing is designed exclusively to accommodate unidirectional axial loads with high efficiency. Manufactured from 52100 Chrome Steel with a stainless steel cage, it delivers reliable performance in demanding environments. Its compact design and precise bearing dimensions (85mm bore, 110mm OD, 19mm width) make it ideal for applications where space constraints and axial load capacity are critical factors.
