Bearing, Leybold, Ruvac, WAU150, WAU250, Part# 26101301

This bearing is a direct replacement for OEM part number 26101301. It is also known as BNG0077 . The bearing is designed to fit your Leybold Ruvac pump perfectly. You do not need to modify anything. Just put it in place of the old worn bearing. Inside your Ruvac pump, parts spin at high speed. The bearing holds those parts in place. It lets them spin freely without touching the sides. This reduces friction. Less friction means less heat. And less heat means your pump lasts longer.

A good bearing also keeps the spinning parts balanced. If a bearing is worn out, the shaft can wobble. That wobble damages other parts. Changing the bearing early prevents bigger problems later.
