Okamoto OH-30G

Rear bearing failure from high belt tension. As the customer increased their feed rates the load to the spindle increased. Coolant splashing on the belt and pulley surface and a worn belt caused the belt to slip. The quick fix was to tighten the belt. This solved the slip problem but eventually caused the rear bearings to fail. A new belt is always cheaper than a spindle repair.
