Colfax's MistLock bearing and lubrication cartridge prevents the entry of external contaminants
Colfax's Lubrication Systems Company has developed the MistLock bearing and lubrication cartridge for air-cooled heat exchangers (ACHEs). MistLock is designed to overcome the disadvantages of grease by supplying a clean, cool and continuous oil mist that evenly coats surfaces. Positive pressure in the cartridge is engineered to prevent entry of external contaminants that could otherwise cause abrasive failure. Additionally, the MistLock bearing cartridge is designed to accommodate up to 20° of axial and parallel misalignment of the shaft, which eliminates the need for shims. The bearing assembly is designed to allow axial thermal expansion of the shaft without restricting rotation.
