Timken roller bearings

Timken Roller Bearings re: Dempster vs. Aeromotor

There are a lot Aeromotor mills out there and if kept oiled they will last for many years. However, IMO the timken roller bearing makes Dempster a more reliable mill.

Understand a guy in California installs timken roller bearings in aermotor windmill heads.

Aermotor oiler issues

The small diameter cylinder oiler the screws in under the plug on the hub picks up oil from the hub & feeds it back down a grove on the rabbit sleeve bearing to the head. If clogged oil will eventually leak from front bearing. Cylinder must be cleaned once a year. Use compressed air & kerosene---when you see it run back into head--it is clean.
