Ultra-Sealed Radial Insert Ball Bearings from the 2..-DLS series are available with a single- or double-lip seal made from extremely abrasion-resistant material. The seals are also protected by a sheet metal cover. Field test have shown that NSK bearings last several times longer than conventional standard insert bearings.
