Autoprop Roller Bearing Systems

Description

Autoprop Roller Bearing Systems replacement kits for the H5 and H6 Autoprop models. Built around a grease lubricated roller bearing system each blade is sealed from the ocean using a lip seal and several O-rings on the blade cap and grease ports. The blades are locked in place using a tab screw and castellated nut to prevent the nut from becoming loose. This tab screw is a custom bolt designed and manufactured by Bruntons Propellers that performs a similar role as a tab washer but is considerably more robust and able to resist much larger forces.
