Flanged Ultra-Thin Ball Bearings
These bearings, which are flanged and have twice as many contact points as angular-contact ball bearings, guarantee accurate positioning inside a tube or housing and can withstand radial loads.
Steel bearings are less resistant to corrosion than 440C stainless steel bearings.
Compared to shielded bearings, open bearings are more effective at dissipating heat.
Although shielded bearings keep out dust and other impurities, they are less effective at dissipating heat than open bearings.
