TYPE: SPB-01

The Superpro Bearing Isolator Type SPB01 is unitized, any attempt to dissemble the Bearing Isolator will damage it. After making any adjustments to the equipment (pump, gear box, turbine, etc) confirm that the Bearing Isolator is still properly installed.
Prior to installation
- Warning! disconnect all systems power and follow all standard safety procedures.

Lead-in chamfers
Keyway Splines
Snap ring grooves - Clean all foreign debris from bore and shaft areas.
Installation
- Lubricate bore and shaft O rings with system compatible lubricant.
- Position the Bearing Isolator over the shaft by hand. Bearing Isolator position is correct if the stator O ring is towards the bearing housing.
- Slide down the Bearing Isolator towards the shaft, stopping just before the bearing housing of the equipment. Use hand pressure only.
- Rotate the Bearing Isolator so that the drain port is centred at the 6 o’clock position. Press Bearing Isolator into bore using hand pressure only. If necessary, gently tap Bearing Isolator into bore using a soft faces tool.
