Over the years a great deal of R&D has been carried out to find bearing designs coupled with appropriately specified lubricants. This takes into account the specific features of the bearing, the lubricant specification, and the requirements of the industries we serve. key considerations are vertical load, axial load, dynamic effects, rotational speed range, temperature ranges, hygiene and many others too numerous to list. Standard off the shelf bearings are not designed and specified to meet the exacting specification needed for our ice machines.
The same can be said of the water seals we specify
We have had to put right the carnage created when the wrong parts have been used, as the bearings inevitably fail prematurely and often cause significant damage.
Using alternative bearings literally is false economy.
