Just wondering on the results that machines have had with the aftermarket Swing Bearings? Pricing differences and longevity etc. Thanks
the lifetime of ordinary slewing bearing is usually 7-8 years, it can work 30000 hours in theory. Price differences of slewing bearing depends on the precision grade and steel materials.
The major cost of bearings is the cost to install them and the amount of money the machine looses while it is not working. Add those up and the price difference between the best and worst bearing is not much.
