    Open sealedshield


    Open bearings dissipate heat more efficiently than shielded and sealed bearings.

    Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.

    Sealed bearings block out dust and other contaminants better than open and shielded bearings, but retain the most heat.
