MistLock™ Bearing

The Mistlock™ Bearing from Total Lubrication Management‚ a Colfax Fluid Handling company‚ is a breakthrough in oil mist lubrication – for Air-Cooled Heat Exchangers – or‚ ACHEs.

MistLock provides all the benefits of oil mist to ACHEs and eliminates 100 percent of stray mist that could potentially foul heat transfer characteristics. Before MistLock‚ the only alternative was grease. But high temperature operation of fans supported by these bearings led to lubricant breakdown‚ and bearing failure was a common result. Maintenance was often delayed or ignored as these devices were typically located in hard-to-reach locations.

The MistLock Bearing cartridge eliminates these problems. It offers a single‚ automated lubrication method – a clean‚ cool and continuous oil mist that provides even coating for all bearing surfaces. This completely-sealed‚ closed-loop environment accommodates up to 20 degrees of axial and parallel shaft misalignment. That means no need for shims.

The patent-pending design of the MistLock Bearing system also provides a safeguard against failure due to extreme forces exerted on bearings from the shaft’s axial thermal expansion. The bearing housing provides positive pressure for the oil mist‚ external contaminants cannot enter – and that guards against bearing failure.
