Metric Miniature Flanged Bearings

Open

Sealed

Shielded

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.

Miniature Extended Bearings

Open

Shielded

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.
