Yamazaki YBH-45 Spindle Repair
Our customer sent us this spindle for repair after their part quality diminished. The bearings were very tight and had noticeable damage when spun by hand. We also noted that an aftermarket speed sensor had been installed on the spindle but not balanced with the spindle assembly. This caused high vibration and ultimately bearing failure.
We manufactured a custom counterweight to offset the speed sensor. Thoroughly cleaned the spindle and assembled it with new bearings.
After reassembly of all components, adjusting bearing preload, and undergoing break-in and testing procedures, this spindle passed our final quality inspection before being returned to our customer with a 1-year warranty.
