- Open motor bearings contain no seals, or are not shielded from outside elements. Sealed motor bearings contain an outer shell, called a shield, which encloses the bearing components.
Expense
- Open motor bearings come at the cheapest price due to their lack of a shield element. Sealed motor bearings, pricier than open bearings, vary in expense based on the type of seal materials used.
Debris
- Open motor bearings, though easier to lubricate and capable of a better spin than sealed bearings, can suffer in performance if debris clogs the bearing components. Open motor bearings can also lose lubrication due to lack of a seal. Sealed motor bearings keep debris out and lubrication in, helping ensure better performance and a longer working lifespan.
