The Nachi thrust ball bearing model 51100 is a precision axial bearing designed to support unidirectional thrust loads. It consists of two hardened steel washers and a brass cage containing precision steel balls. The inner diameter measures 10 millimeters, the outer diameter 24 millimeters, and the total thickness 9 millimeters. The steel used is high-carbon chrome type with surface hardness between 60 and 64 HRC. Its optimized contact geometry ensures uniform load distribution and reduced wear under continuous operation. Dimensional tolerances follow ISO 199 standards with a P6 accuracy class.
The Nachi 51100 thrust ball bearing operates reliably within a temperature range from minus 20 to plus 120 degrees Celsius. Lubrication is typically performed with NLGI-2 grease or ISO VG 68 oil to minimize friction. Its brass cage provides excellent resistance to fatigue and corrosion, ensuring stability at speeds up to 7000 RPM. This bearing is commonly used in light machinery, precision instruments, and power transmission systems. Due to its high durability and precise structure, it is regarded as one of the most reliable engineering options for axial load applications.
